Abstract

The invention relates to a steering tool applied to electric-driving directional crossing, particularly to a well track control tool for electric-driving directional crossing. The steering tool mainly comprises a casing, a male electrical connector, an electrical connector tailstock, a terminal box, an electrical cable assembly, a reducing module and a female electrical connector, wherein the casing comprises an upper casing and a lower casing; the upper casing is connected with the lower casing through a groove; the electrical cable assembly comprises an electrical cable outlet connector, an electrical cable and motor power lines; one end of the electrical cable is connected with the male electrical connector through the terminal box, and the other end of the electrical cable is connected with the female electrical connector through the terminal box; two motor power lines penetrate through the electrical cable outlet connector and the cable respectively, so that electric connection of corresponding phases is realized; the reducing module comprises a motor, a coupler, a wing block, a lead screw and a sliding block; the motor is connected with the lead screw through the coupler; the lead screw is sleeved with the sliding block; the wing block is connected with the sliding block through a T-shaped groove; and the sliding block moves linearly on the lead screw and drives the wing block to stretch out radially. According to the steering tool applied to electric-driving directional crossing, the structure is simple; the operation is easy; and intelligent and automatic well track control can be realized.

Description

technical field [0001] The invention relates to a guiding tool for electric-driven directional crossing, an auxiliary tool for reaming used in the field of pipeline directional crossing, and belongs to the technical field of oil and gas drilling devices. Background technique [0002] In the directional crossing of pipelines, in order to solve the problems of insufficient reaming power, low efficiency, and high failure rate in the working conditions of large pipe diameters, long distances, and complex strata, as well as to solve the problem of signal transmission distortion or cable Due to the problems of troublesome loading and unloading, easy breakage, and high failure rate, an electric drive directional traversal reaming method was proposed. The electric-driven directional crossing reaming method transmits high-power and strong electricity from the ground to the underground through the intelligent drill pipe that can transmit power and signals (see patent number: ZL2014106...
