南沙二上2+3油藏该项目针对油藏综合含水高,隔层小,剩余油分布零散;基于高分辨层序地层格架,建立了精细地质模型,并对隔夹层分布、沉积微相及沉积模式进行研究;通过数值模拟及油藏工程方法,确定了剩余油分布规律;依据剩余油在宏观和微观上的分布比较零散的特点,立足井组进行挖潜;依据隔夹层研究成果,利用分层手段强化二、三类层的动用,对应油井实施差异性提液与卡堵水相结合,提高油藏层间动用程度。
Nansha 2 Upper 2 + 3 Reservoirs The project aims at the high comprehensive reservoir water content, small interval and residual oil distribution. Based on the high resolution sequence stratigraphic framework, a fine geological model is established and the distribution of interbeds, sedimentary microfacies And sedimentary model. Through the numerical simulation and reservoir engineering methods, the distribution rules of remaining oil were determined. Based on the characteristics of the remaining oil in the macro and micro distribution, the potential well was tapped in the well group. Based on the research results of the intercalation, Stratified means to strengthen the use of two or three types of layers, corresponding to the implementation of the differential wells and card plugging the water wells to improve the degree of interaction between the reservoir.
