Intelligent pilot downhole tool vibration test tool

Abstract

The invention relates to an intelligent pilot downhole tool vibration test tool comprising a base, clamps and a connector, wherein the base comprises a bearing face and a connecting face opposite to the bearing face, and the bearing face is parallel to the connecting face; the clamps comprise a first clamp and a second clamp, and the first clamp and the second clamp are arranged on the bearing face of the base at an interval and are used for carrying out two-point fixation on a measured object; and the connector is connected with the connecting face of the base, and the connector is used for being connected with a vibration table. When a vibration and impact simulation test is carried out on a tested object through the vibration table, the two ends of the tested object are stressed and are supported by the base, and vibration and impact force are effectively transmitted, so that data such as acceleration designed by the vibration test can be accurately obtained, and the environmental adaptability and reliability of an instrument can be verified; the problems of poor test effect and the like caused by violent shaking of two ends due to the fact that only the middle of a tested object is stressed can be solved.

Description

technical field [0001] The invention relates to the technical field of vibration tests, in particular to an intelligent drilling-guided downhole tool vibration test tooling. Background technique [0002] The intelligent drilling guide system is a relatively advanced drilling and logging tool in the petroleum field at present. When working in the downhole, it faces a working environment with strong vibration and strong impact. Vibration and shock simulation tests verify the environmental adaptability and reliability of the instrument. Downhole tools such as intelligent drilling-guiding rotary steerable instruments and nuclear magnetic detection instruments are mostly slender cylinders. The fixture connects the measured object with the vibration table, and the fixture is set in the middle of the measured object. During the vibration test, the measured object only bears the force in the middle, resulting in violent shaking at both ends and poor force consistency; The actual v...
