Description

Power rotor device for hydraulic-magnetic driven wellbore cleaning tools

Technical field

The present disclosure relates to the technical field of drilling equipment, and in particular to a power rotor device for a hydraulic-magnetic drive wellbore cleaning tool.

Background technique

During the drilling process of oil and gas resources, the drill bit breaks the formation to form a wellbore, but during the crushing process, cuttings are formed. Most of the cuttings are carried to the surface through the drilling fluid circulation, but a small part of the cuttings cannot be cleaned out of the well in time. When the hole is opened, cuttings accumulation will occur, forming a cuttings bed. Especially in wells with complex structures such as extended reach wells, horizontal wells, and highly deviated wells, cuttings beds can easily form. Cuttings beds can cause stuck pipes, twisted drilling tools, etc. A series of drilling accidents.

At present, the more common wellbore cleaning technologies at home and abroad include: increasing the drilling fluid return velocity, improving the rheological properties of the drilling fluid, and short tripping drilling tools, etc., although these technologies can achieve the purpose of destroying the cuttings bed and removing cuttings to a certain extent. , but there are also many shortcomings and areas that need improvement. The existing more advanced patent (201510078623.5) discloses an integrated blade hydraulic-magnetic drive wellbore cleaning tool, which converts the hydraulic kinetic energy inside the tool into rotational kinetic energy, and transfers the rotational kinetic energy of the cleaning blade to the permanent borehole through the magnetic force between the magnetic couples. Magnetic cuttings and cleaning blades are not affected by whether the drill pipe rotates or not, and can achieve a better cutting effect in horizontal long-reach wells. However, this method also has certain shortcomings. For example, the efficiency of converting hydraulic kinetic energy into the rotational kinetic energy of the cleaning blades is relatively low. The cleaning blades are all designed in one piece, which is difficult to adapt to the working conditions of various formations, and the blades need to be damaged after damage. Overall replacement greatly increases subsequent maintenance costs.

In view of this, there is an urgent need for a new type of power rotor device for wellbore cleaning tools on the market to solve the problems of low rotational kinetic energy conversion efficiency and difficulty in adapting the cleaning blades of the existing integrated blade hydraulic-magnetic drive rotor device. Problems in working conditions of various strata.
