摘　　要：为有效提高低渗透油藏压裂井的产能,针对低渗透油藏中流体渗流的复杂性问题,考虑启动压力梯度和介质变形系数的影响,建立了两种区域下油井稳定渗流的产能公式。研究结果表明,油井产量随变形介质系数和启动压力梯度的增加而降低,随裂缝半长和生产压差的增加而增加。因此,制定合理的油井生产制度及适当的采取压裂增产措施,对油井经济有效地增产十分重要。In order to enhance the oil production of fractured wells in low permeability reservoirs,two production equations of oil wells are established under different fluid fields considering starting pressure gradient and deformation media coefficient. The calculation results show that production of oil well drop with the increasing of deformation media coefficient and starting pressure gradient,while rise following with fracture and pressure differential increasing. Therefore,it is important to make a reasonable production system and take measures to improve productivity for oilfields.
