Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] figure 1 A drill tool assembly 100 according to one embodiment of the invention is shown. like figure 1 As shown, the drill tool assembly 100 includes a drill bit 60 , a motorized drill 61 , a first stabilizer 62 and a drill collar 63 . Wherein, the power drilling tool 61 is arranged above the drill bit 60 and is configured as a power drilling tool 61 capable of providing a descending force, so as to transmit the ground input torque and rotational speed to the drill bit 60, and can output additional torque and rotational speed to the drill bit 60. The drill bit 60, the power drill 61 can improve the anti-slant effect. The first stabilizer 62 is disposed above the power drilling tool 61 to provide pendulum force and enhance the stability of the drilling tool assembly 100 . At the same time, the cooperation of the first stabilizer 62 and the power drilling tool 61 ...

Abstract

The invention provides a drilling tool assembly. The drilling tool assembly comprises a drill bit, a power drilling tool which is disposed above the drill bit and capable of providing a deviation reduction force, a first stabilizer disposed above the power drilling tool, and a drill collar disposed above the first stabilizer. The drilling tool assembly has the advantages of high anti-deviation ability and stable operation of the drill bit.

Description

technical field [0001] The invention relates to the technical field of petroleum engineering drilling, in particular to a drilling tool assembly. Background technique [0002] Although the drilling technology of petroleum engineering has developed rapidly, many well types such as vertical wells, directional wells, horizontal wells, extended-reach wells, and multi-branch wells have appeared successively, but they all have vertical wellbores with a high proportion of drilling footage. The high-efficiency anti-deviation and fast drilling technology has always been the focus of research in the drilling industry. [0003] However, the drilling tool assembly in the prior art has relatively poor anti-deviation fast drilling effect, and cannot meet the development of high-deflection anti-deviation fast drilling. Contents of the invention [0004] Aiming at part or all of the above-mentioned technical problems existing in the prior art, the present invention proposes a drill tool ...
