摘要
石灰泥调剖剂是利用水体改造中处理剂石灰的副产物 (残渣 )配制而成 ,文中通过分析水处理残渣的物化特征 ,研究对不同油藏特点的石灰泥及其复配堵剂的筛选 ,并采用岩心流动模拟实验测定封堵大孔道的封堵效果。结果表明 :石灰泥调剖剂能有效地封堵高渗地层 ,起到增油降水的作用 ,解决了环境污染 ,达到增收节支、变废为宝的目的。
By using lime residue in water leg rebuilding,lime cream profile control agent is prepared.The paper analyses the physicochemical feature of water treatment residue,researches the screening of lime cream and compound plugging agent for the different reservoir feature,and determines the result of plugging the big pore path by applying core flow simulation test.Through field application,the results show that the lime cream profile control agent can effectively plug the high permeability reservoir,increase oil and decrease water,and solve environment pollution.Meanwhile,the aims of increasing income and decrease expenditure,and changing waste into useful one are attained.
