Abstract

The invention discloses a probe sleeve with shock-proof and anti-collision performance, which mainly comprises a probe sleeve main body and is characterized in that the probe sleeve main body is provided with a probe measurement main body sleeve 23 and a shock-proof and anti-collision body, wherein a scintillator chamber 4 and a photomultiplier chamber 8 are arranged in the probe measurement mainbody sleeve 23, and a glass window 6 is arranged between the scintillator chamber 4 and the photomultiplier chamber 8; and the shock-proof and anti-collision body 24 of the probe sleeve main body is arranged at the lower end of a photomultiplier seat 21, and one to more groups of pressing rings 9, 15 and 18 and one to more groups of springs 12, 14 and 16 are arranged in the shock-proof and anti-collision body 24 to buffer shock and collision. The probe sleeve has the advantage of greatly reducing the damage rate of a scintillation gamma probe to below 10 percent from 20 percent.

Description

(1) Technical field [0001] The invention relates to an accessory of a petroleum well logging device, in particular to a probe cover with anti-shock and anti-impact performance. (2) Background technology [0002] For the detection of gamma rays, scintillation detectors have high detection efficiency and are widely used. A scintillation detector is mainly composed of a scintillator and a photomultiplier tube. The most widely used scintillators are sodium iodide and cesium iodide, both of which are glass crystals with a density greater than 4, and the photomultiplier tube uses an optical glass shell. Since these two devices are glass bodies, they are easily broken when they encounter vibration or impact. However, during the maintenance operation, transportation, and underground movement of the gamma instrument, vibration or impact is unavoidable. According to previous statistics, out of 100 gamma meters used, about 20 of them were damaged, and these damages were all caused b...
