摘要
综述了低渗致密储层尤其是鄂尔多斯盆地储层的压裂技术难点,针对低渗、低孔致密油藏,提出了提高低渗透致密油藏产量的措施,阐述了3种低渗透油藏压裂液—胍胶压裂液、聚合物压裂液和清洁压裂液各自优缺点和特性,重点介绍了清洁压裂液种类和特点、成胶原理、破胶原理,展望了清洁压裂液的未来发展趋势。
The technical difficulties of fracturing fluid for low permeability reservoir especially reservoir in Erdos basin were summarized. The characteristics, advantages and disadvantages of the guar gum fracturing fluid, polymer fracturing fluid and clean fracturing fluid were described. Types, char-acteristics, gelation process and gel breaking principles of clean fracturing fluids were chiefly introduced. Development trend of clean fracturing fluid was prospected.
