摘要
根据质量守恒原理和渗流力学理论,由压裂时的破裂压力及破裂前泵注的累计液量等数据,推导了储层有效渗透率的计算公式。经其与常规油藏模拟法的计算结果对比,该公式计算结果可靠,方便快捷,对实时调整部分压裂设计参数及进行压后评估分析,都具有一定的指导作用。
Abstract
Using such data as the fracturing pressure during fracturing operation and the total volume of pumped fluid before fracturing,while basing on Mass Conservation Law and seepage mechanics,the calculating equation of formation effective permeability is derivated.This equation is proved to be reliable and simple,and it can be used in adjusting the fracturing parameters in real time and for evaluation after fracturing.
