AI Technical Summary

Technical Problem

The maintenance cycle of hydraulic modules in existing rotary guide systems is long, costly, time-consuming, and labor-intensive, which restricts the scale of rotary guide system adoption.

Method used

A dynamic impact device is adopted, including a guide frame and a piston impact structure. The reciprocating motion of the piston is realized by a solenoid valve mechanism and a pin assembly, replacing the hydraulic module. The impact of the guide plate is realized by controlling the flow of drilling fluid through the solenoid valve.

Benefits of technology

It reduces maintenance costs and difficulty, shortens maintenance cycles, reduces the number of parts and assembly/disassembly time, lowers mechanical structure costs, improves wear resistance and erosion resistance, and reduces the risk of stuck drill bits.

Abstract

The application provides a dynamic beating device and relates to the field of oil production engineering, and solves the problem that the existing rotary steering system has a long maintenance period, high cost, time-consuming and labor-intensive through a hydraulic module. The device comprises a guide framework (1) and a piston beating structure (2); the guide framework (1) is respectively provided with the piston beating structure (2) and a circuit board in the upper and lower end slots; the top of the piston beating structure (2) is provided with a guide plate (6), the piston beating structure (2) drives the guide plate to open and close to beat the well wall; the piston beating structure (2) and the circuit board are electrically connected through a solenoid valve mechanism and a pin assembly; the pin assembly comprises a male pin (214) and a female pin (10). The dynamic beating device realizes the replacement of the hydraulic module, shortens the maintenance period, reduces the use cost, saves time and labor.
