Study on the optimal plug size design of weak alkaline ternary composite driven in block II7-12 of an oilfield A
The Second Oil Production Plant of Daqing Oilfield Co., Ltd., Daqing, Heilongjiang 163414, China
The weakly alkaline ternary compound drive block in Block A II7-12 oil formation is the first block in an oilfield to adopt the lipopeptide compounded weakly alkaline ternary system for industrial production, and the explored target layer II7-12 belongs to Class IIB+ Class III oil formation. In view of the nature of the oil formation in the block, a study combining indoor physical model rating and numerical simulation was carried out, and the optimization of the size of the extended ternary main and secondary plugs was taken in the process according to the dynamic response at the right time to further improve the recovery rate and increase the economic benefits.
Key words: Class II B+III reservoir / plug / numerical simulation / enhanced recovery
