基于计算机模拟的煤层气开采方法及增产对策分析

Analysis of Production and Countermeasures in Coal Seam Gas Exploitation Based on Computer Simulation Method

煤层气开采是煤炭资源合理利用的有效方式。文章以不同渗透率煤层气开采为研究对象,利用计算机仿真技术模拟了直井压裂、洞穴完井和水平完井3种开采方式,将煤层按渗透率分为低渗透煤层、中渗透煤层和高渗透煤层。根据每种渗透煤层的不同,制定了符合实际情况的开采方式。该研究为我国煤层气开采工艺的优化提供了参考。

Mining coal gas is the effective way to the rational utilization of coal resources. In this paper, taking the different permeability coal-bed methane mining as the research object, using computer simulation technology is used to simulate three kinds of mining methods, vertical well and horizontal well completion, cave completion, the coal seam is divided into low permeability coal seam, middle permeability coal seam and high permeability coal seem. According to each different permeability coal seams, the mining method in line with the actual situation is developed, This study provides reference for optimization of mining technology in China coal seam gas.
