耐温230℃的新型超高温压裂液体系
A New Fracturing Fluid with Temperature Resistance of 230 ℃
摘要
Abstract
The natural vegetable gum fracturing fluid presently in use works effectively at temperatures up to 177 ℃.To fracture formations with higher temperatures,a fracturing fluid with temperature resistance of 200-230 ℃ has been developed with ultrahigh temperature thickening agent,high temperature resistant zirconium crosslinking agent,high temperature stabilizer and efficient gel breaker through large quantity of laboratory experiments.The experimental results showed that,under the synergetic effect of these additives,the fracturing fluid is suitable for use in fracturing formations whose temperatures are higher than the temperature limit of conventional gels.The fracturing fluid has good shear-resistance property at high temperatures up to 230 ℃,and the polymer consumption for formulating the fracturing fluid is obviously reduced.Complete gel breaking can be realized with the fracturing fluid,and damage to the fluid conducting formations with proppants is low.关键词
