北一区断东西块葡一组油藏精细描述及预测

A Fine Reservoir Description and Prediction of Pu I Formation of the West Block of Beiyiquduandong in the Sazhong Oilfield

当前油田面临着深度开发的严峻形势 ,需要多学科协同研究 ,来实现提高原油采收率的目的。油藏开发现实更需要精细、准确、定量地预测出井间各种砂体内部非均质性及其三维空间分布规律。以萨中油田北一区断东西块葡一组为实例 ,通过应用高分辨率层序精细对比、流动单元定量表征、沉积微相条件控制的储层建模、油藏数值模拟等方法进行综合研究 ,揭示了河流 -三角洲相储层定量的非均质特征 ,从宏观角度表征了砂体内部剩余油分布 ,建立了油藏综合模型。多学科油藏研究为精细油藏描述与预测提供了实用手段 ,提高了油藏预测水平 。

Now the Daqing oilfield is faced with severe situation of deep development, and multiple subjects are needed to go along together in order to enhance recovery factor. Reality of oilfield development still needs forecasting interior heterogeneity and space distribution laws of three dimensions of all kinds of sandbody between wells carefully,exactly,quantitatively.This paper takes the example of Pu I formation of the west block of Beiyiquduandong in the Sazhong oilfield, with the application of the methods of fine contrast of high resolution sequence, quantitative token of flow units, reservoir modeling controlled by the sedimentary microfacies, reservoir numerical simulation to carry out the comprehensive study. The paper opens out quantitative heterogeneity of river delta facies reservoir, thus the distribution of remaining oil in sandbody inside is showed from the point of view of macroscopic, and reservoir comprehensive models are set up. The study of multiple subjects the practical means for fine reservoir description and prediction, and improve prediction level,it has practical significance for the same reservoir fine study of oilfield.
