摘要
煤层压裂所产生的裂缝十分复杂,常规的裂缝数值模拟不适合煤层压裂分析。本文针对煤层气压裂后产生的非对称水平缝,根据其形成的机理与条件,建立非对称水平裂缝的数学模型;对模型进行求解,并研发相应的软件。以新疆阜康白杨河大倾角区块为例进行实例分析,模拟结果与微地震检测结果基本吻合,验证该模型的准确性。
The fracture produced by coal reservoir fracturing is extremely complicated,and the conventional numerical simulation of fracture is not suitable for analyzing coal seam fracturing.According to the formation mechanism and conditions of asymmetric horizontal fractures after coalbed methane fracturing,a mathematical model of asymmetric horizontal fractures is established in this paper.The model is solved and the corresponding software is developed.A case study of Baiyang River Block shows that the simulation results are in good agreement with the results of micro-seismic detection,which could verify the accuracy of the model.
