Experimental device for testing key component of rotary side wall coring instrument

Abstract

The invention relates to an experimental device for testing a key component of a rotary side wall coring instrument. The experimental device comprises a first sealing cavity which comprises a first cavity shell, and the interior of the first cavity shell is used for arranging a motor and a hydraulic pump connected with the motor; an external connector assembly is connected with the left end of the first cavity shell in a sealed mode, and an oil injection hole and a wiring hole which are communicated with the interior of the first cavity shell are formed in the external connector assembly; a transition connector assembly is connected with the right end of the first cavity shell in a sealed mode, an oil outlet hole and an oil return hole are formed in the transition connector assembly, the oil outlet hole is communicated with the oil outlet end of the hydraulic pump through a connecting pipe, a backflow assembly is arranged on the right side of the transition connector assembly, and a flow channel communicated with the oil outlet hole and the oil return hole is formed in the backflow assembly. According to the experimental device, the structure of the testing device can be simplified, the experimental device is suitable for simulation testing in a laboratory, the testing period is greatly shortened, and meanwhile the testing cost is greatly reduced.

Description

Technical field [0001] The present invention belongs to the field of petroleum testing equipment, particularly relates to an apparatus for experimental Rotary sidewall member favorite key test. Background technique [0002] With the rapid development of oil, natural gas and other industries, the application of rotary sidewall favorite to take more and more widespread, and more and more popular in the industry. However, as more and more demanding land and sea exploration wells working environment, well, high temperature (210 ℃), high pressure (140MPa) and other harsh environment has become common rotary sidewall coring condition. Now domestic sidewall coring device in response to such a condition is still stable performance, low reliability, fault occur frequently, especially in key parts of the motor, hydraulic pumps and hydraulic motors, fails more frequently, but there is no may be feasible in a laboratory test program is completed, only the high temperature and pressure simula...

AI Technical Summary

Problems solved by technology

At present, the performance of domestic shaft wall coring equipment is still unstable when dealing with such working conditions, the reliability is low, and failures occur frequently, especially the key components such as motors, hydraulic pumps and hydraulic motors. The feasible test plan that can be completed in the laboratory can only be simulated in the high-temperature and high-pressure well. This high-temperature and high-pressure well is the only experimental equipment, and the cost is high and the experimental period is relatively long. The cost of on-site operations and other aspects is relatively high, which leads to uncontrollable test time and extended product development cycle.
