表面活性剂压裂液机理与携砂性能研究
Research on Mechanism and Sand-Carrying Performance of the Surfactant Fracturing Fluid
摘要
Abstract
By applying experimental methods of transmission and scanning electron microscopy and the basic theory of surfactant solution, the relevance of surfactant inhesion and extrinsic in macroscopic and microscopic of surfactant are analyzed, and the gel forming mechanism and the gel breaking mechanism are investigated. The mechanism of surfactant fracturing fluids carrying sand mainly by elastic is demonstrated, and we put forward the new method by using suspending shear force to indicate the sand-carrying capacity of surfactant fracturing fluid. The results of experiment indicate that the minimum sand-carrying viscosity are 100 mPa-s and 30 mPa-s in the same 100s"1 shear rates for guamdine gel fracturing fluid and surfactant fracturing fluids; in the same shear rate, minimum sand-carrying viscosity of surfactant fracturing fluid is much smaller than guanidine gel. The above research results enrich the correlate knowledge in theory, and it helps surfactant fracturing fluid application.关键词
