摘要： 在Wiggins等人针对达西流的工作基础上,推导出含启动压力梯度流动下的产能方程,为解析IPR曲线方法在低渗、特低渗透油藏中的应用提供了依据。同时,对影响流入动态的主要因素进行了敏感性分析,结果表明在含启动压力渗流的流入动态关系式的影响因素及其作用规律与达西流有明显的差异,论证了目前低渗油田普遍采用大压差、密井网生产的理论基础。并且根据所建立的方程分析了靖安油田长6特低渗储集层的生产动态特征,分析结果显示该方法较常规方法能更好地预测此类储集层的产能

Abstract: The inflow performance relationships (IPR) with starting pressure gradient are presented based on Wiggins' Darcy flow work, which supports application of IPR analytical technique in low and extremely low permeability reservoirs. In this paper, sensibility analysis for affecting major inflow-performance factors is made, showing that IPR with starting pressure and its process differ significantly from those of using Darcy flow. It is demonstrated that production of low permeability reservoir is theoretically based on the process of big pressure difference and close spacing in general. According to the new equations proposed here, the well performance characteristics of Chang -6 extra-low permeability reservoir in Jing'an oilfield are analyzed, proving its better predictions of such a reservoir productivity than present conventional methods.

Key words: IPR curve, starting pressure, low permeability reservoir, productivity evaluation
