Abstract

The invention relates to the electronic pressure gauge field, in particular to a downhole electronic pressure bomb. The downhole electronic pressure bomb comprises an upper joint, wherein a connector lug and a middle joint are respectively connected with two ends of the upper joint, a battery is arranged in the upper joint, a lower joint is connected with the end of the middle joint, a sensor is arranged in the lower joint, a support is arranged in the middle joint, the support is respectively connected with the battery and the sensor in detachable mode, and a circuit board is further installed on the support. According to the downhole electronic pressure bomb, the support is respectively connected with the battery and the sensor in detachable mode, and simultaneously the circuit board is installed on the support, and therefore direct welding connection between the circuit board and the sensor is avoided, the design can facilitate maintenance of the downhole electronic pressure bomb, and when the downhole electronic pressure bomb breaks down, the circuit board or the sensor can be separately replaced, integral replacement is not needed, unnecessary resource waste can be reduced in maintenance, and maintenance cost of the product is reduced.

Description

technical field [0001] The invention relates to the field of electronic pressure gauges, in particular to a downhole electronic pressure gauge. Background technique [0002] In the process of oil field exploration and development, the pressure and temperature testing and monitoring of oil and gas field formations are important tasks in oil testing and production testing, and are also the data cornerstone for formulating well site production systems, determining well site production, and calibrating well completion conditions. In order to correctly evaluate the oil and gas equivalent of mineral formations, it is of great practical significance to measure the pressure and temperature of oil and gas bearing layers in time and accurately. [0003] Electronic pressure gauges are widely used to measure and record the pressure and temperature values ​​of oil, gas, water and other media in oil and gas field formations. The existing electronic pressure gauge generally directly welds...
