摘要
利用二维单相油藏模型和裂缝模型,研究了压裂井的产量预测方法。分别考虑了裂缝导流能力随时间的变化、压裂井中尾随加砂等情况,对无限大地层和五点法注水井网边界进行了模拟预测计算,绘制了无因次典型曲线,并与不考虑导流能力随时间变化的典型曲线进行了对比。文中建立了生产预测模型,提出在压裂设计的同时进行产量预测,以此调整方案,达到最优设计。
A two-dimensional and single-phase reservoir model and afracture model were used to study the performance and predict production in fractured wells. On the basis of prior work,several conditions are considered in simulation, such as variation of fracture conductivity with time, two section conductivities in a fracture caused by tail-in proppant, infinite reservoir and five spot pattern boundaries. Simulated calculation under these conditions was made and corresponding type-curves were drawn up..
