Abstract
A hydraulic oscillation tool with variable stage, small pressure drop and strong impact based on radio frequency identification is provided. It includes a conversion connector, a disc spring upper bracket, a disc spring housing, a disc spring group, a multi-stage piston shaft, an upper piston sleeve, a first radial sealing ring, a double-female-buckle piston sleeve, a double-male-buckle piston sleeve, a second radial sealing ring, a double-female-buckle lower piston sleeve, an end piston, an impacting connector, a power housing, a power shaft end cap, a high torque turbine, a power shaft, a lower connector, a rotating valve, a bearing supporting ring, and a turbine special bearing. The hydraulic oscillation tool realizes the low pressure drop and strong impact, and thus the problems that with the continuous increase of horizontal length, excessive pressure drop will make the annular pressure drop sharply, and drilling fluid circulation is difficult are solved.
