三元复合驱技术在我国已进入矿场试验阶段,为进一步提高原油采收率提供技术支持。在试验过程中一些非均质性比较严重的区块出现三元复合驱后期高渗透层吸水量大于水驱阶段吸水量,低渗透层吸水量少于水驱阶段的吸水剖面反转现象。利用物理实验,对影响原油采收率的各种因素进行总结,结合矿场试验对改善吸水剖面反转的相关技术进行研究,对提高三元复合驱驱油效果具有指导性意义。
三元複閤驅技術在我國已進入礦場試驗階段,為進一步提高原油採收率提供技術支持。在試驗過程中一些非均質性比較嚴重的區塊齣現三元複閤驅後期高滲透層吸水量大于水驅階段吸水量,低滲透層吸水量少于水驅階段的吸水剖麵反轉現象。利用物理實驗,對影響原油採收率的各種因素進行總結,結閤礦場試驗對改善吸水剖麵反轉的相關技術進行研究,對提高三元複閤驅驅油效果具有指導性意義。

ASP flooding technology has come to field test stage in China,which provides technique support for EOR.The phenomenon of reverse of fluid entry profile emerged In some blocks with relatively severe heterogeneity,that is the high permeability zone absorbs more water during later ASP than water flooding era,while the middle and low permeability zones absorb less than in water flooding stage.Physical experiments have been conducted to study the factors affecting oil recovery efficiency,and related technologies are studied based on field tests to improve ASP effect of the fluid entry profile for reference.
