Abstract

Abstract: Analytical development equation of inflow performance relationships(IPR) under non-Darcy flow was proposed on the base of Wiggins'work.It will be the basis of IPR's application to the low-permeability reservoirs.According to the new equation,the threshold pressure(or its gradient)could be determined from the data of production or the welltest analysis.An engineering application was done in Chang 6 of Jing'an low-permeability reservoir.The results are compared with the data from different sources,such as the data from the experiment and pressure buildup analysis.It shows the new method is simple and can satisfy the precision of engineering analysis.

Key words: inflow performance relationships, threeshold pressure, low-permeability, production evaluation, analytical method

摘要： 在Wiggins对达西流工作的基础上,推导出低速非达西渗流的产能方程,为流入动态关系(IPR)曲线方法在低渗、特低渗透油藏中的应用提供了理论依据。根据所建立的IPR方程,探索了利用多个生产数据或试井数据来快速确定启动压力或启动压力梯度的工程应用问题。对靖安油田长6特低渗储层的计算结果表明,虽然各个井所在储层的启动压力可能相差较大,但所获得的启动压力梯度却基本接近,这与研究区内储层物性相差不大的结果相吻合。应用结果也表明,该方法所得结果与试井分析以及岩心实验结果具有可比性,而该方法使用更简便,且结果可满足工程分析的精度要求。
