Research on Coal-Formed Gas Reservoir Combined Qualitative and Quantitative Methods

Abstract:

At present, coal is still the primacy of China's energy structure, and this situation will not change in a short time. Coal-formed Gas Reservoir quality and the predicting method have also become one of the urgent needs to address the issue of energy exploration, but the lateral variation of the coal-formed gas reservoir is a common geological phenomenon in the coal mine, if the prediction error is too large, it will greatly impact on the production of coal mine. Especially in the area where has complex structure characteristics, the reservoirs are impacted by structural changes, the reservoir predicting become the most important job and the most difficult job. This paper take the example of DaCheng, the research carried out the sedimentary reservoir characteristics, the coal body structure, the coal thickness, the heterogeneity of the coal seams and collapse columns of coal reservoir, and then reservoir fine evaluation was done combined Micro and Macro, Qualitative and Quantitative methods.
