摘要
在沉积微相研究及储集层参数定量研究的基础上 ,应用灰色聚类分析方法 ,对柴达木盆地红柳泉油田E13 低渗透岩性油藏的储集层进行了综合评价 ,分析了储集层的分布规律和影响各类储集层发育的因素及其对油气分布的控制作用。研究结果表明 ,沉积相控制着各类储集层分布的总趋势 ,有利的沉积相带可以发育高质量储集层 ,但后期成岩作用的强弱对储集层质量的影响更为重要 ,有利储集相带均分布在碳酸盐含量较低、胶结作用较弱的区域 ;沉积后期成岩作用的不均一性是造成各类储集层平面不连续分布特征的主要因素。图 3表 1参
In order to evaluate the E 1 3 ultra low permeability lithologic reservoir in Hongliuquan oil field, Qaidam basin, a research on reservoir distribution is carried out with the method of grey cluster analysis on the basis of investigating microfacies and reservoir parameters quantitatively. The influence factors of each type of reservoir and their control effects on oil gas distribution are analyzed. The results show that the distribution of the sedimentary facies controls the overall tendency of the distribution of various kinds of reservoirs, namely, the favorable sedimentary facies belts may develop high quality reservoir. However, the post sedimentary diagenesis has stronger influence on the development of the reservoir quality. The favorable reservoir facies belts are generally in the areas where is low carbonate content and weak cementation, and vice versa. Moreover, the heterogeneity characteristics of post sedimentary diagenesis caused the isolated and discontinuous planar distribution of all types of reservoir. So, the grey cluster analysis method is worth spreading for reservoir comprehensive evaluation.
