摘要
Abstract
The water development of Yan9 reservoir in Sansheng area of Yanchang Oilfield has caused problems such as rapid decline in oil out-put,rapid rise in water cut and frequent well shutdowns.The evaluation is made from the form of well pattern,the density of well pattern,the degree of production of water cut,water drive index,water retention rate and water consumption rate.The results show that the Yan 9 reservoir in the study area is dominated by unidirectional and bidirectional effective Wells,with 84.28%water drive control degree and 66.84%forma-tion pressure holding level.In order to maintain formation energy,water injection should be strengthened,but considering the ultimate water de-velopment,the injection-production ratio of well groups should not be too high.The research results can guide the scientific and efficient devel-opment of Yan9 reservoir,and provide theoretical basis for the next fine waterflood development and adjustment measures.关键词
