沈阳油田东胜堡变质岩潜山油藏渗流特征研究

通过大量的室内模拟实验资料．对沈阳油田东胜堡变质岩潜山油藏的各项渗流特征进行了较为系统地分析研究，得出该类油藏油气水渗流以裂缝孔隙为主，并具双孔隙特点；在注水开发中，应主要考虑裂缝非均质较强的影响．以防止油藏过早水淹和水沿大裂缝突窜，造成含水上升速度快，驱油效率低的后果。

STUDY ON THE PERCOLATION CHARACTERIZATION OF BURIED HILL RESERVOIR IN METAMORPHIC ROCKS OF DONGSHENGPU AREA OF SHENYANG OILFIELD

Through quite a lot of data of laboratary simulated experiment, systematic analysis and study were carried out on the percolation characterization of metamorphic buried hill reservoir in metamorphic rocks of Dongshengpu area,Shenyang oilfield.The result shows that this type of reservoir has the features of fracture pore and double pore in the course of percolation of oil, gas or water. In the process of waterflooding,the effect of severe heterogeneity of fracture should be mainly considered in order to prevent the reservoir from watering out too early and water break through along the wide fracture,resulting rapid increase of water cut and low efficiency of oil displacement.
