Abstract: To solve the technical problem of anti-oblique drilling in the complex working conditions of deep wells and ultra-deep wells, the idea of developing a static thrust-type mechanical vertical drilling tool that can be used economically, safely, and reliably under the condition of high temperature and strong vibration was proposed. The friction resistance of the key components of the dynamic and static disc valve group was calculated, and the finite element analysis of the clearance flow of the ring valve was carried out. The ring valve structure and flow channel were designed based on the rapid shut-off response law of the high and low sides of the well, and the ground hydraulic bench test of the ϕ177.8 mm static thrust-type mechanical vertical drilling tool was carried out using the full size test bench. The results show that to reduce the friction area of the disc valve, a combination of two layers is recommended. The upper part is designed with a special-shaped hole and boss, and the lower part is designed with a special-shaped bypass. The hard alloy material is used for integral molding. The clearance between the upper and lower disc valves is controlled at 0.5 mm, and the height of the boss of the upper and lower disc valves is controlled at 0.25 mm. Through the ground bench test, it is proved that the dynamic and static disc valve group can direct and shunt the water flow normally. The performance index of sealing and pressure-holding has reached the expected design requirements. The results can provide a reference for structural design optimization of static thrust-type mechanical vertical drilling tools.
