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。
The limestone profile control agent is prepared by using the byproduct (residue) of the treatment agent lime in the water body modification. By analyzing the physicochemical characteristics of the water treatment residue, the paper studies the screening of the lime mud and its compounding plugging agent with different reservoir characteristics , And the plugging effect of large pore blockage was determined by core flow simulation experiment. The results show that the lime-mud profile control agent can effectively block the high permeability formation, increase the oil precipitation, solve the environmental pollution, and achieve the purpose of increasing income and saving and turning waste into treasure.
