Problems solved by technology

However, the sample should be exposed to the air during the process, which will easily lead to the mixing of gas, and it is easy to leak gas during the crushing process, which will make the experimental results smaller
[0026] (3) The curve fitting method is a purely theoretical calculation, the method is simple and easy to implement, but it is greatly affected by the previous desorption data, and the calculation results are prone to errors
[0027] (4) In the high-temperature method measurement, the gas in the closed pores of shale is difficult to desorb, and the residual gas cannot be completely measured

Abstract

The invention relates to a shale residual gas content testing system. The shale residual gas content testing system comprises a closed shale sample crushing device, a residual gas content measurement mechanism and a computer, wherein the closed shale sample crushing device comprises a motor, a large reduction gear, a small reduction gear, a sun wheel, a planet wheel and a closed ball milling tank and is used for crushing a shale sample to be in a form of below 60 meshes under a closed condition; the residual gas content measurement mechanism is provided with a temperature sensor, a pressure sensor, a power supply and a data acquisition card, wherein the sensors are used for measuring all parameters inside the closed ball milling tank; the computer is provided with residual gas content testing software for processing, computing, storing and inquiring data measured by the measurement device and can automatically compile and print a measured report after the measurement. The shale residual gas content testing system can achieve the original closed shale crushing and the final residual gas content measurement, and is high in automation degree, easy to operate and reliable in measurement result.

Description

technical field [0001] The invention relates to a shale residual gas content testing system, which is composed of a rock sample airtight crushing device, a residual gas content measuring mechanism and a computer equipped with self-programmed software, and belongs to the field of geological exploration. Background technique [0002] Residual gas refers to the natural gas that remains in the core after the normal analysis of shale rock samples is terminated, or the natural gas that can only be obtained after a longer period of time. Usually, it is difficult to resolve from the sample during natural analysis. Or even through some means, the analysis may not be complete, resulting in some residual gas remaining in the sample. [0003] According to the survey results of market products, at present, there is no complete set of equipment or systems in my country that can realize the measurement of shale residual gas from rock sample crushing to measurement. Common measurement metho...
