摘要
综合考虑启动压力梯度、压力敏感性和压裂缝导流能力衰减对低渗透油藏弹性开发的影响,提出了一种新的低渗透油藏弹性开发产能分析和弹性采收率计算方法。现场实际数据计算验证了新计算方法的正确性,可实现低渗透油藏弹性开发产能变化规律和弹性采收率的分析和预测。
A new method of analyzing the productivity and calculating the recovery factor of low permeability reservoirs developed by elastic drive is proposed by taking account of the effects of threshold pressure gradient,pressure sensitivity and the decrease of fracture conductivity.The method has been validated by field data,allowing analysis and prediction of the productivity and recovery factor of low permeability reservoirs developed by elastic drive.
