摘要:
针对低渗透油田具有非均质以及流体流动启动压力梯度的特点,基于椭圆流理论给出了具有启动压力梯度的非均质油藏压裂井产能计算方法,利用该方法可以定量评价平面非均质性质以及启动压力梯度对压裂井产能的影响。研究表明,启动压力梯度越大、非均质性越强,压裂井产能越低。基于产能计算方程,得到了平面非均质低渗油藏压裂井的有效动用半径,为低渗油藏压裂井的生产以及相关研究工作提供了重要借鉴。
Abstract:
According to the features of threshold pressure gradient and anisotropy of low -permeability oilfields,a productivity calculation method of fractured well is proposed by using the elliptic flow theory.The effect of the heterogeneity and threshold pressure gradient on the productivity was quantitatively evaluated by this method.The study results show that the greater the threshold pressure gradient and heterogeneity are,the lower the productivity of the fractured well is.Based on this formula,a method for calculating the effective drainage radius is obtained to provide important references for the production of fractured wells and related research work.
