重复压裂技术是低渗透油田增加单井产量确保油田稳产的关键手段,八面台油田储层渗透率低,注采关系差,常规重复压裂后油井增产效果不理想。本文分析了常规压裂增产效果差的原因,引进了体积压裂改造理念,分析体积压裂增产机理、体积压裂可行性、体积压裂工艺及参数、形成了老井体积压裂重复改造配套工艺技术,现场应用效果显著。
The technology of repeated fracturing is a key means to increase single well output in low permeability oilfield to ensure stable production in oilfield. The reservoir permeability of Badamtai oilfield is low, the relationship between injection and production is poor, and the stimulation effect of conventional wells after repeated fracturing is not satisfactory. This paper analyzes the reasons for the poor effect of conventional fracturing stimulation, introduces the concept of volumetric fracturing, analyzes the mechanism of volumetric fracturing stimulation, feasibility of volumetric fracturing, volumetric fracturing technology and parameters, Technology, on-site application of significant results.
