水基压裂液用聚合物增稠剂评述

Review of Polymer Densifiers in Water - base Hydrofracturing Fluids

增稠剂是压裂液中的主要化学成分,增稠剂的性能直接影响压裂液的性能。目前使用的聚合物增稠剂品种很多,大致可分为天然植物胶及其衍生物、纤维素衍生物以及合成聚合物3大类,对此3大类聚合物增稠剂的应用状况及性能作了较详细的评述,并提出聚合物增稠剂性能改进方向。

The densifier is the main chemical component in the fracturing fluids and its properties directly affect using properties and the results of hydrofracture. There are many kinds of polymer densifiers in use and they can be categorized as natural plant gums and their derivatives, celluloses and their derivatives, and artificial polymers. A-mong them, the plant gums and their derivations have been put to the most extensive use in China and other countries . In the future some polymer densifiers should be exploitated with the properties such as no residue, the slightest destruction and high temperature stabilities, etc.
