摘要
针对克拉玛依三2区克下组砾岩油藏储层非均质性严重的特点,分析了影响克拉玛依三2区克下组砾岩油藏流动单元的基本因素及其相互关系,并运用概率统计方法,将研究区储层流动单元划分为4类,研究结果表明Ⅰ、Ⅱ类流动单元的物性和储集性能较好,油井初期产量高,主要分布在研究区南部及中部偏东地区;Ⅲ类流动单元连续性也较好,目前剩余油饱和度较高,是油藏进一步挖潜的目标;Ⅳ类流动单元渗流性质中等偏差,分布面积小,储量丰度低;同时流动单元的分布主要受控于微相砂体的分布。
There existed serious heterogeneities in conglomerate reservoir of Kexia Formation of Karamay Oilfield. By using the analysis of the basic influential factors on flow units and the interrelationship of all the factors,the reservoirs in the oilfield are divided into 4 classes according to the basic theory of flow units and probability statistics analysis.Then the identification pattern of the flow units is established for the flow unit classification of the whole reservoirs.The study reveals that the I and Ⅱflow units have good physical property and storage capability,initial potential of oil-well is high,most of which are distributed in the south region of the study area.Ⅲ flow units have good physical property and storage capability. Currently,The remaining oil saturation is higher and it is the new target of reservoir development.
