Abstract
The system monitors position of a drilling or tubing string coupling in BOP
stack to provide safe opening/closing of RAM preventers around a drilling or tubing string in an underbalance drilling, snubbing or any operation on live wells.
Top sensor device placed under rotary table and above BOP stack consists of 2 sets of sensors; one detects position of a coupling and the other measures drilling or tubing string movement and defines movement direction. Bottom sensor device, placed in between BOP
stack and wellhead, consists of sensors that detect coupling position.
Information from sensors is gathered by an electronic controller and sent to a PC with custom made specialized software for processing. Processed information is then displayed on the display unit as cross-section, or transparent digital image of BOP stack and its internal elements, as well as full image of drilling or tubing string and coupling in real time.
Display unit is positioned conveniently for a driller.

Description
BOP Drill String and Tubing String Monitoring System TECHNICAL FIELD:
The invention pertains to drilling process and weil services. It monitors position of a drill string or tubing coupling or cross sectional change in relation to the ancillary BOP snubbing stack or to the drilling rig BOP stack in order to provide safe opening/closing of RAM
preventers above or below drill string or in an underbalanced drilling, snubbing or any operation on live wells where snubbing or stripping operations occur.
DESCRIPTION OF PRIOR ART:
To the knowledge of the author's there is no prior art that performs the function of this invention.
It is very important to know the exact position of a coupling in BOP stack in order to provide safe opening/closing of RAM preventers around a drill string or tubing string.
Establishing of the exact position of a coupling is performed manually by individual measuring of drill pipes.
BOP Drill String Monitoring System possesses numerous benefits and advantages over manual procedures. In particular, it provides the driller or snubbing unit operator with a cross section formatted, computer generated real-time transparent digital image of the snubbing and / or drilling rig BOP stack along with an image of the drill string or tubing couplings as related to one another. The driller or snubbing unit operator is able to track the movement of the cross sectional change or couplings and to determine their exact position in the BOP stack relative to BOP RAM preventors which enables him to open/close RAM preventers around a drilling string or tubing string in fast, but safe manner.
Because of the aforementioned, work safety is significantly increased, and savings in time and resources are remarkable. Once data regarding pipe geometry / length has been entered into the data base, manual measuring of drilling tubulars is no longer necessary.
SUMMARY OF THE INVENTION:
BOP Drill String Monitoring System enables on-line monitoring of the coupling position in BOP stack. Top and bottom sensor devices detect couplings and cross sectional changes as they move past. Data from the sensors is sent to a PC which correlates that data with drill string position in relation to the BOP stack. The correlated data is then processed to provide a digitalized picture of the drilistring / tubular as related to the BOP stack. The geometry of the snubbing BOP or drill rig BOP, including exact positioning of the BOP
RAMs must be manually entered to tie the correlation between the drill string tubulars and the BOP stack. Processed input data and manually entered BOP configuration are then generated in to a real-time picture of BOP stack with position of RAMs and the exact position of couplings and their movement and it is shown on a driller's display unit.

Figure 1. - Layout of the system DETAILED DESCRIPTION OF THE INVENTION:
BOP Drill String Monitoring System consists of four main units (Figure 1.):
top sensor (1) device, bottom sensor device (2), electronic controller unit (3), PC with the specialized monitoring software (4) and driller's or operator's display (5). Top sensor device (1) is an electro-mechanical device positioned under the rotary table and above BOP
stack (8). It consists of 2 sets of sensors; one that detects position of a coupling (9) and the other that measures drill string (10) or tubing string (10) movement and it defines movement direction. Information gathered is sent to electronic controller unit (3) through Ex-barrier (6).
Bottom sensor device (2) is flanged between the wellhead (7) and BOP stack (8). It is an electronic device that is comprised of one set of sensors that detect coupling (9) position.
Information gathered is, again, sent to electronic controller unit (3) through Ex-barrier (6).
Electronic controller unit (3) is a device that collects information from sensors and sends the data to a computer equipped with the specialized monitoring software (4) for further processing. BOP layout and dimensions are manually entered in the software (4). Based on the information entered and data received from top sensor device (1) computer software (4) creates the database of drill string (10) or tubing string (10) and generates a real-time picture of BOP stack (8) as a cross section view or transparent image with the actual position of couplings (9). Picture of BOP stack (8) and coupling position (9) is shown on a driller's or operator's display (5) enabling driller to safely open/close RAM
blowout preventer (11) around the drilling string (10) or tubing string (10).
Information gathered by bottom sensor device (2) is used as a safety mechanism that verifies data logged on in previous run-in trip of drill string (10) or tubing string (10) during the running of drill string (10) or tubing string (10) out of well. If this system is used for running of drill string (10) or tubing string (10) out of well without previous run-in trip data available the information from Bottom Sensor Device (2) is used together with the data from the top sensor device (1) to generate real-time picture of BOP stack (8) with the actual position of couplings (9).
