Abstract

An anti-tripping water power pressure device overcomes the defects that accidents of looseness and tripping of connecting threads of the existing water power pressure device parts occur caused by strenuous vibration of a drilling tool. A cylinder body assembly comprises a cylinder I, connecting sleeves, a cylinder II, a cylinder III and an inner hexagonal sleeve. The cylinder I, the connecting sleeve, the cylinder II, the connecting sleeve, the cylinder III and the inner hexagonal sleeve are sequentially and fixedly connected with each other from top to bottom. The minimum inner diameters of the cylinder I, the cylinder II and the cylinder III are equal to each other and larger than the inner diameter of each connecting sleeve. A radial through hole is formed in each connecting sleeve. The upper end of a piston rod II of a piston rod assembly is fixedly connected with a piston rod I. The lower end of the piston rod II is fixedly connected with an outer hexagonal rod through a connector. The outer hexagonal rod is arranged inside the inner hexagonal sleeve. At least two pistons are arranged in an annular space which is arranged between the piston rod of the piston rod assembly and the cylinder of the cylinder assembly. The anti-tripping water power pressure device has the advantages of being reasonable in structure, and capable of continuously and flexibility pressuring on a drilling bit in a horizontal well or a large displacement well, improving drilling rate, and effectively avoiding the looseness and the tripping of the connecting threads caused by the strenuous vibration of the drilling tool.
