摘要

小型压裂在油田开发与压裂设计方面起着重要的作用。综述了自80年代以来小型压裂理论模型的进展情况,包括考虑裂缝高度变化的模型、理论求解闭合压力的方法及与压力有关的滤失系数的求解,并介绍了求解近井摩阻的现场方法,为油田更好地进行压裂设计提供了系统的依据和指导。

Abstract

Developing and designing of mini-fracturing acted very important effect in oilfield. The evolution of the theoretical models about mini-fracturing was summed up, which included model considering the change of fracture high and method about calculating closure pressure and filtration coefficient. A field measure that can calculate near bore frictional resistance was introduced. This paper supplies a system foundation and guidance to design of mini-fracturing.
