Abstract

The invention relates to a deflection loading device and testing equipment, including a supporting mechanism; a loading connection mechanism connected to the supporting mechanism for rotating and clamping the object to be measured, and the loading connection mechanism slides to the first position relative to the supporting mechanism. When in a first position, the object under test is bent to a target degree; a first driving mechanism, which is connected with the loading connection mechanism, is used to drive the loading connection mechanism to slide relative to the support mechanism. When the first driving mechanism drives the loading connection mechanism to slide to the first position relative to the support mechanism, the measured object is bent to the target degree, that is, a certain bending angle is formed, and the function of simulating the bottom-hole bending condition is realized.

Description

technical field [0001] The invention relates to the technical field of drilling and logging instrument testing, in particular to a deflection loading device and testing equipment. Background technique [0002] The intelligent drilling guide system is a relatively advanced drilling and logging tool in the petroleum field. When working in the downhole, the maximum bending angle is 18° / 30 meters and the maximum speed is 200r / min. In order to verify the environmental adaptability and reliability of the system, Mechanical strength and fatigue life, it is necessary to simulate the working state of drilling and logging instruments and drilling tools in the downhole drilling process in the laboratory environment, and then judge the drilling and logging instruments and drilling tools (including ordinary oil drilling and logging The indicators of the instrument) are normal, so as to judge its performance stability, reliability and service life. The shape of downhole tools for intelli...
