Abstract

The invention discloses a protecting device for an oil well low-pressure tester. The protecting device comprises a pneumatic wellhead connector with a handle. A biased microphone mounting rack matchedwith a polyvinylidene fluoride piezoelectric film microphone is fixed to the upper end of the pneumatic wellhead connector. A connector for allowing a soundless missile oil well low-pressure tester mainframe to be inserted is arranged on the opposite side of the biased microphone mounting rack, a door for protecting the soundless missile oil well low-pressure tester mainframe is arranged on the outer side of the connector, and a coded lock device is mounted on the door. The soundless missile oil well low-pressure tester can be directly connected to a wellhead and then applied, thus the characteristics of small size and convenient data collection are achieved, the well logging efficiency of the soundless missile oil well low-pressure tester is improved to a certain extent, and the application range of the tester is expanded.

Description

technical field [0001] The invention relates to an auxiliary device used in the field of oil well low pressure testing, in particular to a protection device for an oil well low pressure testing instrument. Background technique [0002] The silent bomb oil well low pressure tester is based on the comprehensive logging instrument, applies the current advanced high-tech technology, and is designed and manufactured in strict accordance with the military industry standard. The abbreviation of bomb comprehensive tester. This kind of advanced pneumatic oil well tester is generally not directly connected to the wellhead due to its bulky size, difficulty in wireless transmission of liquid level test data, and relatively low quality of data transmission. Mode, liquid level test information is transmitted by wire. But at the same time, the problem is that the volume is large, the data collection is inconvenient, and the use environment of the instrument is narrow, which affects the l...
