摘要
对影响页岩气单井产量的基质渗透率、人工裂缝(长度、条数)、天然裂缝(导流能力、连通性)及吸附气量等诸多参数进行模拟。结果发现,页岩气单井产量与上述参数均呈正比,而与天然裂缝间距成反比。通过大量的数值模拟计算进行了图版绘制,用BP人工神经网络法对各因素与改造体积的关系进行训练,以快速确定任意条件下的改造体积形状和大小。
In the process of simulating the effect of matrix permeability,artificial fracture parameters,natural fracture parameters and adsorbed gas volume on shale gas production,the results show that the production is in proportional to matrix permeability,artificial fracture length,artificial fracture number,natural fracture conductivity,natural fracture connection and adsorbed gas volume,and is inversely proportional to natural fracture interval. The data is obtained through orthogonal test method and proved by analytic hierarchy process and Plackett- Burman（ BP）test method. With large amounts of simulations,the calculated plate for quick parameter determination is created.Through practicing the effects of different factors on the shape and size of the stimulated reservoir volume using BP artificial neutral network method,the quick parameter determination for any condition can be achieved.
