Description

Technical Field

[0001] The utility model relates to the technical field of coal seam sampling, in particular to a long-distance directional drilling sampling device for three-soft coal seams. Background Art

[0002] Three soft coal seams refer to coal seams under certain geological conditions, which are characterized by the softness of the coal seams themselves, high water content and complex ground stress. Sampling of three soft coal seams is generally done by accurately measuring the direction of downhole tools through a guidance system and an inclinometer, so as to start the drilling rig and start drilling. The drill bit cuts into the formation through rotation and pressure. As drilling proceeds, the drill core enters the core tube. The drill rod is lifted regularly to take out the positive level of the coal seam in the core tube.

[0003] However, the long-distance directional drilling sampling device for three-soft coal seams in the prior art generally descends vertically for sampling. The changes in geological layers are usually horizontal or oblique. Direct vertical descent will ignore these changes and fail to capture the overall picture and change characteristics of the strata, resulting in failure to obtain sufficiently extensive and diverse geological samples. In view of the above problems, the technicians in this field have proposed a long-distance directional drilling sampling device for three-soft coal seams to solve the above problems.

A connecting rod 8 is fixedly connected to the adjacent side of the two gears 7, and the inside of the limiting groove 4 is slidably connected to the outside of the connecting rod 8. Two limiting blocks 9 are fixedly connected to the front and rear sides of the connecting rod 8, and the inside of the limiting groove 4 is slidably connected to the outside of the limiting block 9. The front and rear sides of the outside of the connecting rod 8 are rotatably connected with a support frame 10, and the inside of the limiting groove 4 is slidably connected to the outside of the support frame 10, and the top of the support frame 10 is rotatably connected to the bottom end of the mounting plate 2.

[0028] Specifically, the limit groove 4 has a fixing effect on the rack plate 5, so that the rack plate 5 can be fixed, and the front gear 7 can drive the rear gear 7 to rotate through the connecting rod 8 between the two gears 7.
