Abstract: This invention relates to a mechanical hydraulic torque converter for horizontal well drilling, and belongs to the technical field of oil and gas drilling tools. The hydraulic torque converter includes a driving shaft, an upper-shell, a driving shaft positioning shell, a TC bearing assembly, a universal shaft shell, a universal shaft assembly, a stator shell, a hollow rotor, a middle-shell, a torque separation assembly, a lower connector, and a confluence assembly. The universal shaft assembly is mounted in the universal shaft outer shell, and two ends of the universal shaft assembly are respectively connected with the driving shaft and the hollow rotor. One end of the confluence assembly is connected with the torque separation assembly, and the other end of the confluence assembly is communicated with an outlet of the lower connector. The tool is jointly driven by the rotating speed of upper drill string and drilling fluid displacement.

Abstract: The disclosure relates to a method for detection of the horizontal and gravity directions of an image, the method comprising: selecting equidistant sampling points in an image at an interval of the radius of the sampling circle of an attention focus detector; placing the center of the sampling circle of the attention focus detector on each of the sampling points, and using the attention focus detector to acquire attention focus coordinates and the corresponding significant orientation angle, and all the attention focus coordinates and the corresponding significant orientation angles constitute a set ?p; using an orientation perceptron to determine a local orientation angle and a weight at the attention focus according to the gray image information, and generating a local orientation function; obtaining a sum of each of the local orientation functions as an image direction function; obtaining a function MCGCS(?), and further obtaining the horizontal and gravity identification angles.
