Flow Unit Correlation And Distribution Of Remaining Oil In Zhongyuan Oilfield Pu53 Fault-Block

reservoir heterogeneous of zhongyuan oilfield pu53 fault-block is verry seriously. it has get high water-cut stage. But water cut and recovery percent is not match. Production effectiveness is bad. So improve reservoir production effectiveness is necessary. This study is base on sedimentology, reservoir geology. High resolution sequence stratigraphy and logging geology is applied. This paper detail study methods that can recognition, classify and evaluate reservoir of zhongyuan oilfield pu53 fault-block. Using the numerical simulation technology, we can know Distribution of Remaining Oil, so we can direct development oilfield. Accomplishment:1, Reservoir is divided into 21 layers and E flow unit, G flow unit, F flow unit and P flow unit.2, Distribution of Barriers and Intercalations is predicted.3, Certain modeling and stochastic modeling is built by reservoir structure approach, threshold approach and 3D modeling approach.4, With reservoir performance analysis and numerical simulation base on flow unit, we can accurately forecast distribution of Remaining Oil to direct development oilfield.5, Microscopic seepage mechanism and microscopic distribution of Remaining Oil is revealed in different flow unit models. On the base, the effect of horizontal wells is well.This paper has created a suit of method how the flow unit classify, correlate, evaluate, forecast. It has overcome in flow unit classify method, flow unit forecast in space, microscopic distribution of Remaining Oil simulation, et al. These conclusions can direct development in similar oilfield.
