摘要
从东濮凹陷深层低渗油气藏地质特点入手 ,论述了压裂改造和地层保护技术 ,进行了压裂选井分析 ,确定了压裂选井方法及压裂时机 ;研究了低伤害预前置液 ,并通过压裂伤害机理分析 ,确定了储层保护方法 ,通过压裂井实例 ,阐明了提高深层低渗油气藏压裂效果的方法。
Based on the geologic characteristics of the deep tight oil & gas reservoir in Dongpu Depression,this article states fracturing stimulation and reservoir protection technique,analyzes the selection of wells for fracturing and determines the methods used to select wells for fracturing and to determine the right time of fracturing operations in different zone.It also studies low harm prepad,and determines the methods for reservoir protection by the way of analysis with fracturing harm mechanism.It states the methods for the enhancement of fracturing efficiency with the deep tight oil & gas reservoir by the case of field application.
