Shale reservoirs have some natural fractures with a certain density and connectivity. The basic percolation model of shale gas reservoir: the black oil model of gas-water phase is used as the basic model, and the dissolved gas is used to simulate adsorbed gas. Accurate description of natural fractures: random distributed discrete fracture model is used as the basic model to describe natural fractures. By comparing the calculation results of single medium (including random distributed discrete fracture model) and double medium model, the model for predicting shale gas productivity is optimized.

页岩气储层体积压裂溶解气模拟吸附气模型优化

页岩储层具有一定的天然裂缝，具有一定的密度和连通性。页岩气储层基本渗流模型：以水-水黑油模型为基本模型，以溶解气模拟吸附气。天然裂缝的准确描述：随机分布的离散裂缝模型被用作描述天然裂缝的基本模型。通过比较单一介质（包括随机分布离散裂缝模型）和双重介质模型的计算结果，优化了页岩气产量预测模型。
