中文摘要:为了解决延长气田Y区域所采用压裂液体系存在水锁、破胶液残渣含量高、储层伤害高等问题,研发了一种Slikwo在线压裂液体系。对Slikwo在线压裂液体系进行室内与现场应用评价。室内实验表明,该压裂液溶胀时间为2min;120℃下,剪切90min粘度在50mPa·s左右;防膨率为80%;岩芯伤害率小于15%;破胶液表面张力24.35mN/m。在延长气田Y区域的应用表明,Slikwo在线压裂液能达到在线混配施工的要求,满足现场加砂要求。

Application of Slikwo online cleaning fracturing fluid in Y area of Yanchang gas field
Abstract:In order to solve the problems of water lock, high content of gel breaker residue and high reservoir damage in Y area of Yanchang gas field,A Slikwo online fracturing fluid system was developed.The slikwo online fracturing fluid system was evaluated in laboratory and field.Laboratory experiments show that the swelling time of the fracturing fluid is 2min;The viscosity is about 50 mPa·s at 120 ℃ for 90 min;The anti swelling rate is 80%;Core damage rate less than 15%;The surface tension of breaker is 24.35mN/m.The application in Y area of Yanchang gas field shows that Slikwo online fracturing fluid can meet the requirements of online mixing operation,meet the site sand requirements
