低渗透岩性油藏的评价方法——以乌里雅斯太油田为例

Evaluation Methods of Low Permeability Reservoir——By Taking Wuliyasitai Oilfield for Example

针对乌里雅斯太油田以低孔低渗型储层为主和岩性、地层油藏的实际特点,在油藏评价研究中结合油藏评价存在的关键问题,应用层序地层学研究、构造模型研究、沉积相与储层预测综合研究、开发矿场试验研究、储层改造研究等方法,并通过实施,不仅有效地提高了油藏评价的效益,也为提高储量动用程度和开发建产提供了有效途径。

In consideration of the characteristics of low porosity and low permeability reservoirs as main reservoirs and lithologic reservoirs,key problems of reservoir evaluation were considered,methods of sequence stratigraphic study,integral study of sediments and reservoir prediction,study of field experiment and as well as reservoir reconstruction were used.The effectiveness of reservoir evaluation is effectively improved and effective means is provided for improving the level of producing reserves and production.
