Problems solved by technology

It is connected to a section of the drill string close to the large-diameter drilling tool and is used to stabilize the drilling direction. It is an important tool to prevent well deviation changes in oil, natural gas and geological exploration drilling projects; in order to achieve high efficiency of wall grinding , the existing stabilizer has a single posture, cannot change the shape according to the downhole situation, and cannot solve the problem of centering the probe in the case of irregular hole walls, which causes difficulties in construction

Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0017] As shown in 1-6, a well logging controllable attitude stabilizer includes a protective tube 4, a plurality of spring columns 9 are installed on one side of the protective tube 4, and the protective tube 4 is connected to the protective tube 9 through the spring columns 9. One side of the pipe two 3 is fixedly connected, and the vibration can be reduced by the spring column 9, so that the stabilizer is more stable. The other side of the protective pipe two 3 is fixedly installed with a ball joint one 7, and the joint assembly 2 is connected to the ball joint one 7 through the ball joint one 7. The other side of the protective tube 2 3 is rotationally connected, ...

Abstract

A well logging controllable attitude stabilizer relates to the technical field of well logging devices and comprises a first protective tube, a plurality of spring columns are mounted on one side of the first protective tube, the first protective tube is fixedly connected with one side of a second protective tube through the spring columns, and a first spherical joint is fixedly mounted on the other side of the second protective tube. The connector assembly is rotationally connected with the other side of the second protection pipe through a first spherical connector, the other side of the connector assembly is rotationally connected with a third protection pipe through a second spherical connector, a supporting rod is arranged in the third protection pipe, a plurality of second righting frames are arranged on the outer wall of the third protection pipe, and a plurality of first righting frames are arranged on the outer walls of the first protection pipe and the second protection pipe. The first centralizing frame and the second centralizing frame are each composed of a plurality of spring frames. The second protection pipe and the third protection pipe are connected through the spherical joint, the problem that turning cannot be achieved in the construction process is solved, the posture of the stabilizer can be changed at will, meanwhile, the first centralizing frame, the second centralizing frame and the supporting rod are additionally arranged, the stability of the stabilizer is improved, and vibration in the construction process is relieved.

Description

technical field [0001] The invention relates to the technical field of well logging devices, in particular to a well logging controllable attitude stabilizer. Background technique [0002] Stabilizer, also known as centralizer, is a tool for stabilizing downhole drilling tools and preventing deflection. It is connected to a section of the drill string close to the large-diameter drilling tool and is used to stabilize the drilling direction. It is an important tool to prevent well deviation changes in oil, natural gas and geological exploration drilling projects; in order to achieve high efficiency of wall grinding , The existing stabilizer has a single posture, cannot change the shape according to the downhole situation, and cannot solve the problem of centering the probe in the case of irregular hole walls, which causes difficulties in construction. Contents of the invention [0003] The invention provides a well logging controllable attitude stabilizer. [0004] In ord...
