无聚合物压裂液作用原理及性能影响因素概述

DVERVIEW ON OPERATION PRICIPIUM AND INFLUENCE FACTORS ON PERFORMANCE OF POLYMER- FREE FRACTURING FLUID

目前 ,国内油井进行压裂施工大部分使用是含聚合物压裂液体系。但含聚压裂液不易破胶 ,返排不彻底 ,会对地层造成二次伤害 ,就此国外首先研制了无聚合物压裂液。对无聚合物压裂液易破胶、易返排 ,低伤害等优越性能和现场应用效果做了详细的阐述 。

In present days, the majority of fracturing construction adopt polymer- bondage fracturing fluid, but polymer- bondagefracturing fluid will damage reservoir again. As to the problem, polymer-free fr acturing fluid was developed first inabroad overseas. The article expatiated pre dominant performance and operation in field of polymer- bondage fracturingfluid polymer-bondage fracturing fluid in fracturing construction is suggested t o be appliad especially in high water sensitivity reservoir at home.
