浅析靖安油田长6储层压裂改造难点及对策

Analysis of Fracturing Difficulties and Countermeasures of Chang6 Reservoirs in Jing＇an Oilfield

靖安油田属于典型的“低压、低孔、低渗”砂岩油藏，压裂改造难度大。通过对靖安油田的长6储层特征进行描述，分析了压裂改造难点，提出一系列有针对性的技术措施，并对效果进行了评价，说明“低压、低孔、低渗”油藏只要采取的加砂压裂工艺及其配套技术得当，仍然可以取得较好的压裂效果。

Jing＇an oilfield is a typical ＂low-pressure, low-porosity, low-permeability＂ sandstone reservoir, with difficulties of fracturing. Chang6 reservoir characteristics of Jing＇an oilfieht is described in this paper, and the fracturing difficulties are analyzed, a series of targeted technical measures is put forward, and results were evaluated. It is indicated that, for ＂low- pressure, low-porosity, and low-permeability＂ oil reservoirs, you can still achieve good fracturing results as long as the sand fracturing process and its supporting technology are taken properly.
