清洁压裂液在水锁性砂砾岩储层中的应用
Application of Clean Fracturing Fluid in Water Locking Glutenite Reservoir
摘要
Abstract
A set of extra-low permeability glutenite reservoir is formed in the fourth member of Shahejie formation on Damintun west slop.The APTi index is used to analysis water locking accurately,and it is proved that thereis serious water locking damage in the reservoir.In this paper,a kind of anti-water-locking clean fracturing fluid composed of surfactant has been introduced.The surface tension of this fracturing fluid which composed of small molecular has stable perforations of temperature and shear resistance.The surface tension can reach 26.75 mN/m after gel breaking,and the water locking damage problems have been solved effectively in this glutenite reservoir.Meanwhile,the fracturing fluid whose damage rate is only 1/3 of the guanidine gel fracturing fluid has no residue and insoluble matter,being beneficial to improve oil production.Finally,the anti-water-locking clean fracturing fluid has obtained good stimulate effect in the construction on site.关键词
