Numerical Simulation of Oil Displacement by Fracturing Imbibition in Horizontal Shale Oil Wells

  • 摘要: 为了提高压裂页岩油水平井产量预测精度、优化闷井时间及压裂液用量等参数,建立了一种考虑压裂液注入、闷井渗吸及开井生产的压裂页岩油水平井油水两相渗流数学模型,利用控制体积有限元法求其数值解,模拟了渗吸作用下基质–裂缝油水置换的过程,获得了油水压力场、速度场、产量及含水率的动态变化。分析了压裂渗吸驱油特征,优化了闷井时间和压裂液用量,并研究了基质渗透率和缝网复杂程度对渗吸驱油的影响。研究结果表明:毛细管力越大,闷井时间越长,则含水率越低,渗吸增产作用越明显;压裂液用量增加能够提高渗吸驱油产量,但同时会引起含水率升高,可通过含水率和产量增幅确定压裂液合理的用量;最优闷井时间受毛细管力、基质渗透率和缝网复杂程度的影响,其中毛细管力和基质渗透率决定了渗吸速度,而缝网复杂程度决定了渗吸面积。所建立的渗吸油水两相渗流模型可为页岩油水平井压裂优化设计提供依据。
