A slip type tool face stabilizer

Abstract

The invention relates to a slip type tool face stabilizer for building angles during well drilling engineering. By the aid of the slip type tool face stabilizer, the problem of easiness in deviation of tool faces in well drilling angle building procedures can be solved. The technical scheme includes that the upper end of an upper barrel is connected with an upper drill string in a screwed manner, the lower end of a lower barrel is connected with a screw drill tool in a screwed manner, and the upper barrel and the lower barrel are connected with each other in a screwed manner; a central pipe is mounted in an inner cavity of the upper barrel, and a spring is compressed by the protruded outer edge of the upper end of the central pipe; a closed chamber formed by the central pipe, the upper barrel and a sleeve is filled with hydraulic oil; the upper end of the sleeve is connected with an end cover in a screwed manner, and the lower end of the sleeve is connected with a slip bowl in a screwed manner; 'T'-shaped hooks at the upper ends of slips are respectively mounted in three 'T'-shaped grooves in the lower end of the slip bowl, the protruded outer edges of two sides of the lower ends of the slips are respectively mounted in grooves of the lower barrel, and the corresponding grooves of the lower barrel are formed in two sides of each of three slopes of the lower barrel. The slip type tool face stabilizer has the advantages that well walls can be clamped by the slips, torque applied to the drill string can be transmitted to the well walls, accordingly, torsional deformation of the drill string can be prevented, and the problem of deviation of the tool faces can be solved; the drill string can rotate in the forward direction without affecting combination well drilling.

Description

technical field [0001] The invention relates to a slip type tool face stabilizer used for deflection building in drilling engineering. Background technique [0002] In the oil and gas industry, horizontal wells and extended-reach wells can develop many oil and gas reservoirs with complex geological factors, increase oil and gas production, and also have the advantages of saving drilling costs and reducing environmental damage. Because horizontal wells and extended-reach wells have good economic and social effects, they are widely used in drilling engineering. [0003] The key to drilling horizontal wells and extended-reach wells is that the wellbore must be deflected. During the deflection process, the tool face of the drilling tool needs to be stabilized. In the actual drilling process, due to the counter-torque effect of the downhole motor, the tool often The deflection of the tool surface requires ground operators to continuously adjust the tool surface, which makes the ...
