A vibration detection device applied to nuclear magnetic instruments while drilling

Abstract

This paper discloses a vibration detection device applied to nuclear magnetic drilling while drilling, which includes a vibration table that horizontally clamps the nuclear magnetic drilling while drilling, and also includes a scale bucket filled with detection liquid. The lower end of the scale bucket is provided with a The groove of the nuclear magnetic instrument while drilling, the arc surface corresponding to the upper surface of the nuclear magnetic instrument while drilling is provided in the groove, the scale barrel is suspended on the upper side of the vibration table, and is connected with the nuclear magnetic instrument while drilling The nuclear magnetic instruments are arranged at intervals, and are used to keep still when the vibrating table vibrates to perform high-voltage emission measurement. This article relates to the field of oil drilling. It provides a vibration detection device applied to the NMR instrument while drilling, which can overcome the problem that the instrument cannot perform high-voltage emission measurement under vibration. It uses a scale barrel suspended on the upper side of the vibration table. When the detector is active, the scale barrel remains still, so that the NMR instrument while drilling can obtain echo signals on the vibration table at the same time, so that the performance can be measured more accurately and the test time can also be saved.

Description

technical field [0001] The invention relates to the field of oil drilling, in particular to a vibration detection device applied to nuclear magnetic instruments while drilling. Background technique [0002] At present, in order to test the performance of the instrument, the existing NMR instruments while drilling need to perform vibration tests on the vibration table. However, in the current test process, the NMR instrument cannot measure the echo signal on the vibration table at the same time, and can only perform a simple vibration test. Only after the vibration is over, the external LCR detection device is used to judge whether the probe is good or bad. [0003] It can be seen from the above that in the above detection process, the instrument cannot perform high-voltage emission measurement under vibration, and cannot effectively detect the performance of the NMR instrument while drilling, and the test process is time-consuming and complicated to operate.
