Problems solved by technology

If the desorption data is automatically obtained by a gas flowmeter, the measurement error of the gas flow rate is large when the desorption rate is low, and the volume of the fluid is easily affected by the ambient temperature and pressure, and the measurement accuracy is insufficient; direct measurement with the drainage of the gas collecting cylinder For gas volume, the measurement precision is insufficient, the influence of human factors is large, the operation is inconvenient and the efficiency is low; most of the existing drainage methods cannot realize continuous real-time measurement, the human error is more obvious during the operation process, and the measurement accuracy is low
However, some foreign air content testers with high precision have high automation and good stability, but most of them are expensive.

Abstract

The invention relates to the technical field of exploration and measuring, and particularly provides a shale gas content tester and a testing method thereof. A sealing tank is arranged on a weight sensor, an analyzer is connected to a gas inlet of the sealing tank by a first metal pipeline connected with a first solenoid in series, a draining port of the sealing tank is communicated with a salt water slot by a second metal pipeline of which one end connected with the sealing tank extends into the bottom of the sealing tank, and the other end of the second metal pipeline extends into the bottom of the salt water slot; an exhausting device comprises a positive displacement pump, an exhausting port of the sealing tank is connected with the gas inlet of the positive displacement pump by a third metal pipeline connected with a second solenoid valve in series, the exhausting port of the positive displacement pump is connected with a fourth metal pipeline connected with a third solenoid valve in series, and the first solenoid valve, the second solenoid valve, the third solenoid valve and the weight sensor are respectively connected with a collecting and control system. The shale gas tester is simple in structure, low in cost, high in testing precision and high in automatic degree.

Description

technical field [0001] The invention relates to the technical field of exploration and measurement, in particular to a shale gas gas content tester and a test method thereof. Background technique [0002] According to the research results of "National Shale Gas Resource Potential Investigation and Evaluation and Selection of Favorable Areas" released by the Ministry of Land and Resources in 2012, the potential of my country's land shale gas geological resources is 134.42 trillion yuan, and the recoverable resource potential is 25.08 trillion yuan. The development potential of shale gas is huge, but the development of this field in my country is still in its infancy, especially the equipment for measuring and evaluating shale gas content is far from meeting the current needs. [0003] Shale gas content is a key parameter to evaluate the original gas volume of shale, and it is of great significance to the evaluation of shale gas content and the prediction of resource reserves....
