对大庆油田进一步开展三次采油技术研究工作的几点意见

Suggestions on further study on EOR In Daqing oilfield

根据大庆油田三次采油工作现状和存在的问题,阐述了今后工作的重点研究方向。在聚合物驱油方面,要运用数值模拟技术整体考虑布井、调剖、注聚和后续水驱4个过程,加强注聚过程中的跟踪与调整,进一步加大抗盐聚合物、CDG和预交联体嘭颗粒调驱力度,提出了二类油层聚驱方面的有关地质、室内实验和数值模拟等方面研究方向。在化学复合驱方面,强调岩心、数模和矿场试验紧密结合,从油藏工程角度开展二次机理研究。最后,强调了探索泡沫复合驱、微生物采油和聚驱后热采可行性。

According to the existing EOR work in Daqing oilfield and its problems, this paper illustrates the important points of the further study. For polymer flooding, numerical simulation technology should be used to consider comprehensively well arrangement, profile control, polymer injection and successive water flooding. The tracking and adjustment in the process of polymer injection must be strengthened, and the polymer flooding control of salt-resistance polymer, CDC and pre-crosslinked body must also be strengthened. It proposes the direction of the study on the geology, laboratory experiment and numerical simulation of the polymer flooding of the second type of the reservoirs. For chemical compound flooding, it emphasizes the combination among core study, numerical simulation and pilot test, and secondary mechanism study in the view of reservoir engineering. Finally, it stresses on the feasibility of foam compound flooding, MEOR and thermal flooding after polymer flooding.
