A high temperature screw drilling tool test bench

Abstract

The invention belongs to the field of drilling tool testing in a petroleum natural gas industry, and specifically relates to a high temperature screw drill test bench. The high temperature screw drill test bench comprises a load system, a water path circulation system, a fixed installation system, a central control system and a drilling tool heating system. The load system comprises a brake, a reduction box and a torque sensor. The water path circulation system comprises a water diversion transmission assembly, a slurry pump and a circulating water pipeline. The fixed installation system comprises a base, a drilling tool holding mechanism and a tail end clamping mechanism. The drilling tool heating system is composed of a plurality of medium heating boxes. The brake, the reduction box, the torque sensor, the water diversion transmission assembly, the plurality of medium heating boxes, the drilling tool holding mechanism and the a tail end clamping mechanism are successively and fixedly connected to the base. A screw drill to be tested penetrates through the medium heating boxes. The high temperature screw drill test bench has the advantages that the drilling tool heating system is provided, and the drilling tool heating system is capable of really simulating the practical conditions of the drilling tool in a well, so that the usage performance of the drilling tool under a high temperature is practically measured.

Description

technical field [0001] The invention belongs to the field of drilling tool testing in the petroleum and natural gas industry, and in particular relates to a high-temperature screw drilling tool test stand. Background technique [0002] With the increase in the number and drilling depth of directional wells, cluster wells and horizontal wells, the ambient temperature and pressure of screw drilling tools in deep wells continue to increase. Screw drilling tools have been popularized and used in major oil fields in China and have achieved good results. The drilling effect is good, but considering the structure and use of the screw drilling tool, the life of the screw drilling tool is relatively short; due to the large depth of the deep hole drilling, it takes a long time to trip, such as the screw drilling tool Downhole drilling due to poor production or repair quality will cause large time and economic losses; and the performance change of screw drilling tools under complex env...

AI Technical Summary

Problems solved by technology

When this kind of drilling tool is used in deep well or ultra-deep well operation, due to the continuous rise of downhole temperature, the rubber expands seriously, and the interference between the stator and rotor is further increased, and the transmission of the drilling tool is often caused by excessive friction torque. The shaft or cardan shaft is broken and the stator is degummed, causing the drilling tool to fail
