压裂技术是油气田开发中用于油气井增产和提高采收率的有效措施之一.水基压裂液(主要是水基冻胶压裂液)由于具有良好携带支撑剂性能和热稳定性,且来源丰富、价格较低,已发展成为油气井增产用的主要压裂液品种.但是,油气井增产用的水基冻胶体系的流变性非常复杂,受到许多因素(例如加热、加热历史、剪切作用、剪切作用的历史和化学杂质等)的影响,至今尚无一种比较准确的表征方法,而此
Fracturing technology is one of the effective measures for oil and gas well stimulation and oil recovery in oil and gas field development.Water-based fracturing fluid (mainly water-based gel fracturing fluid) has good performance of carrying proppant and thermal stability , With abundant sources and low prices, has become the major fracturing fluid species used for stimulation of oil and gas wells.However, the rheology of water-based gel systems for stimulation of oil and gas wells is very complicated due to many factors such as heating and heating history , The role of shear, the history of shear and chemical impurities, etc.), so far there is no more accurate method of characterization, and
