Automatic field analyzer system for non-conventional gas

Abstract

The invention provides an automatic field analyzer system and a testing method for a non-conventional gas. The automatic field analyzer system comprises a gas collecting subsystem, a data acquiring subsystem, a system control subsystem and a data analyzing subsystem, wherein the gas collecting subsystem is used for acquiring gas flow data and controlling the start using of a flow machine; the data acquiring subsystem is used for acquiring air temperature data, air pressure data and gas temperature data; the system control subsystem is used for receiving the data of the gas collecting subsystem and the system acquiring subsystem and sending to the data analyzing subsystem; the data analyzing subsystem acquires data of samples to be tested and sets a measuring method for automatically testing each sample.

Description

technical field [0001] The invention relates to automatic calculation technology for energy exploration, and more specifically, to an on-site automatic analyzer system and testing method for unconventional gas. Background technique [0002] As an emerging energy source, unconventional gas has become the strategic development direction of national energy development. How to evaluate its development potential and the overall reserves of unconventional gas are important indicators to guide future development strategies. [0003] From a traditional point of view, there are two widely used measurement methods: artificial water balance method or artificial container method. A general disadvantage of this measurement method is manual collection, which makes the amount of data collection insufficient. At the same time, due to changes in temperature and pressure in the environment, the expansion or contraction of the gas directly affects the final data results. In addition, there i...

The general disadvantage of this measurement method is manual collection, which makes the amount of data collection insufficient

At the same time, due to changes in temperature and pressure in the environment, the expansion or contraction of the gas will directly affect the final data results.

In addition, it is also impossible to calculate the loss of adsorbed gas in the process of the target layer core being drilled, the core to the ground, and until the core is put into the analysis tank, and this part is often one of the important parts of the total gas content.

[0004] Due to manual measurement, it is impossible to accurately record the loss of gas in each step, which often leads to low measurement data or large errors, which affects the final regression analysis with large deviations and low accuracy.

[0005] In the Chinese invention patent CN100429529C, a method for determining gas layers using full wave train and dipole shear wave logging data is disclosed. This method uses petrophysical characteristics and acoustic wave data to determine the gas content of the reservoir, but does not consider temperature and The impact of pressure, and for special environments, the equipment application rate is low

[0006] In the existing measurement process, there is another technology that is airtight coring. From a technical point of view, this technology is not mature, and the cost is also very high. to a comprehensive census
