Hydraulic variable-level small-pressure-drop strong-impact oscillation tool based on radio frequency identification

Abstract

The invention relates to a hydraulic variable-level small-pressure-drop strong-impact oscillation tool based on radio frequency identification. The device is composed of a conversion connector, a disc spring upper support, a disc spring shell, a disc spring set, a multi-stage piston shaft, an upper piston sleeve, a radial plugging ring B, a double-female-buckle piston sleeve, a double-male-buckle piston sleeve, a radial plugging ring A, a double-female-buckle lower piston sleeve, an end face piston, an impact lower connector, a power shell, a power shaft end cap, a large-torque turbine, a power shaft, a lower connector, a rotating valve and a bearing supporting ring. And a special turbine bearing and the like. The hydraulic variable-level small-pressure-drop strong-impact oscillation tool is characterized in that the hydraulic variable-level small-pressure-drop strong-impact oscillation tool is an impact tool achieving low-pressure-drop strong impact. The problems that the annular pressure is sharply reduced due to overlarge pressure drop along with continuous increase of the horizontal length, drilling fluid circulation is difficult, and a tool which is small in pressure drop but strong in impact is urgently needed are well solved.

Description

technical field [0001] The invention relates to a radio-frequency identification-based hydraulic variable-level small pressure drop strong impact vibration tool, which belongs to the technical field of oil and gas exploitation, and in particular relates to an impact vibration tool. Background technique [0002] With the increase of drilling depth and the decline of formation drillability, unavoidable difficulties such as depressurization and sticking phenomenon often occur in horizontal well sections. The current solution is to install an impact tool immediately behind the power drill, and the greater the pressure drop, the greater the impact force produced. However, with the continuous increase of the horizontal length, the excessive pressure drop will cause the annular pressure to drop sharply, and the drilling fluid circulation will be difficult. Therefore, tools with small pressure drop but strong impact are urgently needed to reduce pressure loss. [0003] In view of t...
