Abstract

The invention relates to a hydraulic oscillation system, which includes an upper joint, a piston, a crankshaft, a connecting rod, and a balance flywheel. The lower joint is connected with the upper joint to form an inner cylinder. On the steps, the oscillating outer casing and the lower socket form an annular space; the upper cylinder liner and the lower cylinder liner are sealed and connected, the piston slides along the inner wall of the upper cylinder liner, and the hemispherical head of the piston is in contact with the hemispherical flow port at the bottom of the upper socket. The upper end of the connecting rod is connected to the piston, and the lower end of the connecting rod is connected to the crankshaft. The crankshaft is located in the lower cylinder liner. The balance flywheel is fixed at both ends of the crankshaft. The outer edge shaft is fixed outside the balance flywheel. The camshafts are connected, and the camshafts all pass through the limit holes of the lower socket and are located in the annular space. The camshafts are equipped with cams, the push rods freely fall on the cams, and the ring wall springs freely fall on the push rods. The invention can generate stable axial vibration, and reduce damage to other parts caused by vibration while improving the rock-breaking efficiency of the drill bit.

Description

technical field [0001] The invention relates to a drilling device used in the fields of petroleum engineering, mining engineering, geotechnical engineering and the like, and in particular relates to a hydraulic oscillation system. Background technique [0002] In order to meet the needs of the development of oil and gas exploration, contemporary oil drilling is mainly extended to deep and complex blocks. With the development of major oilfields, more and more wells with complex structures such as highly deviated wells, horizontal wells and multi-branch horizontal wells are used. The frictional resistance between the column and the borehole wall is increasing, resulting in low drilling weight transmission efficiency, which seriously restricts the drilling speed and extension ability. In the process of deep well drilling, the problems of difficult drilling in hard formations and slow drilling speed are very prominent. In order to meet the needs of new drilling conditions or n...
