摘要:
考虑启动压力梯度和介质变形系数的影响,建立了低渗透油藏垂直裂缝井椭圆流模型。根据此模型可得到不同介质变形系数条件下采油指数-生产压差曲线。计算结果表明:随着生产压差的增大,采油指数也逐渐增大,到达最佳生产压差后,采油指数将随着生产压差的增大而降低;随着介质变形系数的增大,采油指数降低的幅度也随之增大。
Abstract:
Bilinear flow model was established to described seepage law in low permeable reservoirs of media deformation with vertical fracture well considering starting pressure gradient and deformation coefficient.Oil well production index-production pressure differential curve can be obtained according to this model under the conditions of different deformation coefficient.The calculation results show that oil well production index increase with increasing of production pressure differential until it reaches the maximum value,and the decrease range expands with the increasing of deformation coefficient.
