The application of clean fracturing fluid in Qilicun oil production plant

According to the research results of the fracturing fluid and surfactant at home and abroad, useing the multi-disciplinary knowledge and methods of the surface chemistry, rheology and reasoning fracturing engineering to solve the problems of the theory and practice of clean fracturing fluid. It studied completely clean fracturing fluid system and its application technology: the composition and formula of clean fracturing fluid, the performance of clean fracturing fluid, the gelation mechanism of clean fracturing fluid. Finally developed a clean fracturing fluid systems and application technology, which can apply to the actual oil field, solve the guanidine Seoul gel fracturing fluid large disadvantage of the formation damage, the oil fields low permeability reservoir fracture stimulation-effective access to improved. Clean fracturing fluid is applied to the 16 wells of the Qilicun oil production plant, the success rate of 100 %.
