压裂用超临界二氧化碳增稠剂研究进展
Research Progress of Supercritical Carbon Dioxide Thickeners for Fracturing
摘要
Abstract
CO2 fracturing technology can effectively reduce water consumption during fracturing construction and the degree of damage caused by fracturing fluid to reservoirs,and has broad application prospects.However,the pure CO2 fracturing fluid injected into the for-mation has a low viscosity and weak ability to carry proppants,which seriously affects the fracturing effect.Therefore,it is extremely im-portant to use thickeners to increase the viscosity of supercritical carbon dioxide.According to the molecular structure and thickening principle of existing supercritical CO2 thickeners,the CO2 thickeners can be divided into surfactants,polymers,and small molecule com-pounds.The current research status of CO2 thickeners is summarized.The solubility,thickening effect and existing problems of different types of thickeners are analyzed and evaluated.Finally,the future development direction of CO2 thickeners is pointed out.关键词
