面3块沙三上开发对策研究及实施效果评价

Study on development strategies and evaluation of implementation effect in the upper Es3 formation in Mian area

面3块位于八面河油田主体构造带的中部,1987年投入开发。目前油井38口,日产油31 t,采油速度0.21%,自然递减率15.5%。为控制产量递减,提高采油速度,针对该区块两种类型的油藏,进行开发特征总结和剩余油分布规律研究,制订有针对性的开发对策并加以实施,取得较好开发效果。

The Mian 3 block is located in the middle of the main structural belt of Bamianhe Oilfield.The block was put into production in 1987.At present,there are 38 oil wells with the daily oil production of 31 tons,oil recovery rate of 0.21%and natural decline rate of 15.5%.In order to control the decline of production and increase the oil recovery rate,the development characteristics of two types of oil reservoirs in this block have been summarized and the distribution of remaining oil has been studied in recent two years.Finally,targeted development strategies have been established and implemented,and the better development effect has been achieved.
