Definitions
- the present disclosure relates to an apparatus and method for accommodating surge and swab experienced at the bottomhole assembly (BHA) of a drill string during tripping procedures from a marine platform. More particularly, the disclosure provides for a surge relief system carried by the drill string adjacent the drill bit to minimize damage to the formation that could be experienced as a result of movement of the platform during tripping procedures.
- BHA bottomhole assembly
- Drilling for oil and gas off-shore is completed from one of two general types of drilling platforms, namely, platforms that are supported by the sea floor, such as fixed drilling rigs and jack-up drilling rigs, or platforms that float near or on the surface of the water, such as drill ships, spar, semi-submersibles and the like.
- platforms that are supported by the sea floor such as fixed drilling rigs and jack-up drilling rigs, or platforms that float near or on the surface of the water, such as drill ships, spar, semi-submersibles and the like.
- floating platforms move with the waves of the sea and wind
- fixed or jack-up drilling rigs remain fixed to the sea floor.
- Heave removes weight from the drill bit as the ship or rig rides to the crest of a wave, and puts weight back on the drill bit as the ship or rig rides down into the trough between waves. This fluctuation in the force applied on the drill bit severely hinders an operator's ability to drill the well bore.
- floating drilling platforms are equipped with heave compensation systems.
- the heave compensation systems are typically in the form of an active heave drawworks system or a system that is an integral part of the drilling derrick or mounted directly on an extension of the traveling block. Such systems are intended to protect against the effects of heave during drilling operations to ensure appropriate WOB is maintained.
- Figure 1 illustrates a floating platform with a drill string that would be subject to surge and swab effects from heave.
- Figure 2 illustrates a surge relief system in a drill string.
- Figure 3 illustrates a surge relief system in a drill string having a mud motor.
- FIG. 1 With reference to FIG. 1, there is shown a floating drilling platform 10 generally floating at the surface 12 of a body of water 14.
- a wellbore 16 extends into a formation 18 from the seabed 20 and includes wellbore fluid 22 disposed therein.
- a drill string 24 extends down from platform 10 and into wellbore 16.
- the drill string 24 generally includes a bottom hole assembly (“BHA") 26 and a drill bit 28.
- BHA bottom hole assembly
- FIG. 1 persons of ordinary skill in the art will understand that the drill string 24 is being illustrated during tripping of the drill string 24 either into or out of wellbore 16 since the drill bit 28 is not engaged with the formation 18.
- the surge relief system 30 generally includes a plurality of flow passages 32 and pressure relief valves 34 disposed in BHA 26 in order to manage wellbore fluid 22 surge and swab effects resulting from heave of drill string 24 as platform 10 moves about at surface 12.
- BHA 26 includes an elongated tubular member 36 having a first end 38 and a second end 40 with an internal annulus 42 extending therebetween. First end 38 is attached to a pipe string 44 in a well-known manner so that an annulus 46 of pipe string 44 is in fluid communication with annulus 42 of BHA 26.
- BHA 26 includes an exterior surface 48 that is generally exposed to the open wellbore 16 and wellbore fluid 22.
- Drill bit 28 has a proximal end 48 and a distal end 50. Drill bit 28 is also provided with an annulus 52 that extends at least partially through drill bit 28. It will be appreciated that annulus 52 may be open to the wellbore 16 in any of a variety of known configurations, such as via jets (not shown) disposed in the body of drill bit 28 or other openings, such as opening 54, so as to supply drilling mud to wellbore 16.
- the embodiments described herein are not limited to a particular type of BHA assembly or drill bit or configuration of the two; rather, the valves 34 and passages 32 may be accordingly disposed in many different types of BHAs and drill bits disposed on a drill string.
- the surge relief system 30 includes a first flow passage 32a defined in drill bit 28.
- First flow passage 32a has a first port 54 at the distal end 50 of drill bit 28.
- first port 54 is axially disposed so as to open towards the bottom of wellbore 16 when drill bit 28 is positioned therein.
- first port 54 is the opening for annulus 52.
- First flow passage 32a also has a second port 56.
- Second port 56 is preferably positioned between the distal end 50 of drill bit 28 and the second end 40 of BHA 36, although it should be understood that that first flow passage 32a may have any position or orientation so long as it permits pressure relief from flow through first port 54 in drill bit 28.
- second port 56 is disposed at proximal end 48 of drill bit 28, while in other embodiments, second port 56 may be along the length of drill bit 28.
- first flow passage 32a may extend into BHA 26, in which case, second port 56 may be positioned on the exterior 48 of tubular 36.
- a first relief valve 34a is disposed in first passage 32a between the first and second ports 54, 56, respectively. In certain preferred embodiments, valve 34a is adjacent second port 56.
- surge relief system 30 may simply utilize a single passage with a relief valve disposed therein, surge relief system 30 may further include a second flow passage 32b. Although it may be defined in drill bit 28 in certain embodiments, preferably second flow passage 32b is disposed in tubular 36 between the first end 38 and second end 40. Second flow passage 32b has a third port 58. Third port 58 is preferably positioned between the first and second ends 38, 40, respectively, of tubular 36. In preferred embodiments, third port 58 is uphole from second port 56 and defined in the exterior surface 48 of tubular 36.
- second flow passage 32b is in fluid communication with first flow passage 32a so that flow through the system of passages 32 from first port 54 sequentially encounters second port 56 and then third port 58 for discharge of fluid into the wellbore 16 as will be described.
- a second relief valve 34b is disposed in second passage 32b. In certain preferred embodiments, valve 34b is adjacent third port 58.
- surge relieve system 30 includes a valve 60 to block back flow along the annulus of the drill string 24.
- valve 60 is a non-return valve, such as a float valve, ball valve, flapper valve or the like, that is actuated by backflow through the drill string 24.
- valve 60 is positioned in the annulus 42 of tubular member 36, preferably adjacent the first end 38 uphole of passage 32b and relief valve 34b.
- surge relief system 30 may also include a third flow passage 32c. Although it may be defined in drill bit 28 in certain embodiments, preferably third flow passage 32c is disposed in tubular 36 between the first end 38 and second end 40 and uphole of second flow passage 32b.
- Third flow passage 32c has a forth port 62.
- Forth port 62 is preferably positioned between the first and second ends 38, 40, respectively, of tubular 36.
- forth port 62 is uphole from third port 58 and defined in the exterior surface 48 of tubular 36.
- third flow passage 32d is in fluid communication with first flow passage 32a and second flow passage 32b so that flow through the system of passages 32 from first port 54 sequentially encounters second port 56, then third port 58 and then forth port 62 for discharge of fluid into the wellbore 16 as will be described.
- first, second and third passages 32a, 32b, 32c, respectively, are in fluid communication with the internal annuli 42, 52.
- portions of the annuli form a parts of the respective first, second and third passages 32a, 32b, 32c.
- one or more of the passages 32a, 32b, 32c may form a portion of an overall passage 34.
- a third relief valve 34c is disposed in third passage 32c.
- valve 34c is adjacent forth port 62.
- the passages 32a, 32b and 32c may be angled relative to the axis of the drill string 24 to control flow of the wellbore fluid therethrough.
- a passage may be angled uphole so that uphole movement of the drill string will drive wellbore fluid through port 56 into the passage, down and out through the first port 54.
- passage 32c is oriented axially upward so that uphole movement of the drill string will drive wellbore fluid through port 62 into the passage, down and out through the first port 54.
- surge relief system 30 may also include a fourth passage 32d isolated from the first, second and third passages 32a, 32b, 32c.
- Fourth passage 32d is preferably disposed in drill bit 28 and includes a fifth port 64 and a sixth port 66.
- fifth port 64 is axially disposed so as to open towards the bottom of wellbore 16 when drill bit 28 is positioned therein.
- Fourth passage 32d may include a fourth relief valve 34d disposed along fourth passage 32d between the fifth and sixth ports 64, 66.
- FIG. 3 a surge relief system 30 similar to that of FIG. 2 is illustrated, but where one or more passages 34 are isolated from fluid communication with annulus 42. This may be the case where annulus 42 is part of another system, such as a mud motor 68 as shown in FIG. 3.
- surge relieve valves 34a, 34b and 34c may have adjustable activation pressures or otherwise may be selected to activate upon a certain pressure threshold.
- activation pressures for all of the valves 34 would be higher than the mud circulating pressure utilized during drilling.
- the activation pressures for valves 34a, 34b, 34c may be set to sequentially higher activation pressures.
- the activation pressure of valve 34a may be lower than the activation pressure of valve 34b, which may likewise be lower than the activation pressure of valve 34c.
- one or more transducers 70 may be disposed in the passages 34 and valves may be activated utilizing a control system 72 either positioned locally or at the surface. Additional valves 34 in additional flow passages may likewise be selected to activate based on a predetermined fluid pressure. Finally, surge relieve valves 34 may be one-way or two-way. As described below, in certain embodiments of the disclsoure, flow through the valve in one direction is utilized to minimize the effects of surge on the formation, while flow through the valve in the opposite direction is utilized to minimize the effects of swab on the system.
- a drill string 24 having a BHA 26 and drill bit 28 with the surge relief system 30 is positioned in a wellbore 16.
- the system is utilized during periods when drilling, i.e., engagement of a drill bit with the formation, has been suspended.
- the system is most useful during dripping of the drill string into or out of the wellbore.
- downward heave on the drill string resulting from wave action will force the drill bit down into the wellbore fluid.
- the wellbore fluid will be forced through the first port and driven into the first passage.
- the first relief valve is actuated, allowing the flow to pass through the second port and back out into the wellbore.
- the second and then the third relieve valves will actuate, to allow the flow to pass through the corresponding ports back out into the wellbore.
- the backpressure valve can be activated to prevent the fluids from passing pack up the drill string.
- wellbore fluid can pass through the second, third and fourth ports into the surge relief system where the fluid can be forced out of the first port in the drill bit, thereby minimizing the creation of low pressure in the wellbore by virtue of a sudden upward movement of the drill string.
- flow passages may take various shapes or routes through the BHA and drill bit.
- ports for the flow passages may be positioned at a number of locations along the overall BHA/drill bit assembly without limiting the disclosure.
