2010年，苏里格气田东区开始水平井开发试验，由于储层地质条件差，对伤害更为敏感，且多段改造沿用中、西区的常规羟丙基压裂液体系，裂缝和储层伤害大、压后返排困难，压后测试平均无阻流量仅为3．88×10^4m^3／d，改造效果十分不理想。2011年，在前期大量室内研究和现场试验的基础上，分别应用羧甲基胍胶压裂液体系、低浓度羟丙基胍胶压裂液体系、阴离子表面活性剂压裂液体系等三种低伤害压裂液体系开展了8口水平井压裂试验，现场施工顺利，压后返排快，测试平均无阻流量31．63×10^4m^3／d，增产效果明显。低伤害压裂液的试验成功为苏里格气田东区水平井储层改造开辟了新的方向，为苏里格气田增产增效奠定了基础。

In 2010 because Reservoir geological condition is poor,more sensitive to damage and use hydroxypropyl fracturing fluid system , the result of horizontal well development test is not well. After pressing test the average open-flow capacity is only 3.88×10^4m^3/d.In 2011, based on a large number of laboratory study and field tests,carboxymethyl guanidine gum fracturing fluid system,low concentration hydroxypropyl guanidine gum fracturing fluid system and anionic surfactant fracturing fluid system were applied in 8 horizontal well fracturing tests. Field construction smoothly,after pressing fluid flow back fast.After pressing test the average open-flow capacity is only 31.63×10^4m^3/d.The increase production emotion is obvious.Low damage fracturing fluid test is successfull in the sulige horizontal well and opened up a new direction.
