一种新的无机防砂剂在水环境中可自行固结成人造多孔岩层,以填补油层实体亏空,阻挡砂粒运移,防止出砂。着重从固结与防砂机理、优化配方研究、温度对人工岩层团结的影响、抗老化与抗介质腐蚀研究、CMAS人造岩心润湿性及有效渗透率测试和孔隙大小分布测试等室内研究出发,介绍了该防砂剂的自固结特性,同时介绍了现场应用及效果。

A new kind of inorganic sand control agent can be solidifies to manmade porous rock in aqueous environment,so as to replace solid voidage of a reservoir,stop the sands from migrating and prevent the sands from producing. This paper introduces the selfsolidification characteristics of the sand control agent, the mechanisms of sand control,formula optimizing research,effect of temperature on solidification of the artificial rock,research of antiaging and erosion resistance,as well as the wettability,effective permeability test and pore size distribution test of CMAS artificial core. Meanwhile,this paper introduces the field application and its results too.
