Abstract

China has abundant reserves of coalbed methane, shale gas and tight gas, which are widely distributed and constitute an important part of China's unconventional oil and gas resources. If only a single gas is developed, it will be difficult to exploit, with low output and economic benefits. Therefore, the technology of "three-gas combined production" of coal measures is of great significance to increase the degree of reserve utilization, reduce the development layer size, and increase the gas production and mining life of a single well. In this paper, CMG numerical simulation software is used to numerically simulate and analyze the interlayer interference of coal measure "three-gas combined production" well, and the factors such as daily gas production and cumulative gas production, pressure field and gas saturation distribution of single-layer and three-gas combined production are respectively compared and analyzed, which provides reference for the knowledge of productivity law of "three-gas" combined production and the analysis of interlayer interference factors.
