摘要
在岩心观察描述、测井及开发动态资料综合分析的基础上,对苏德尔特油田贝16断块兴安岭群储层沉积特征及非均质性进行了研究,并分析了它们对注水开发的影响。结果表明:研究区在兴安岭群沉积时期主要发育滨浅湖沉积背景下的扇三角洲前缘的沉积,其中扇三角洲前缘水下辫状河道不等粒砂岩及粗砂岩储层物性最好,河口坝中粒砂岩次之,远砂坝粉砂岩最差;除了Ⅱ油组以外,其它油层的储层非均质性较强。应当根据沉积微相的平面分布特征及储层非均质性的强弱采取不同的开发措施。
According to core observation, well logging and boring, as well as the development performance data, reservoir sedimentary characteristics and heterogeneity and their effects on the flood development of block Bei 16, Xing＇ anling Group in Sudeerte oilfield were comprehensively studied. The results show that the Xing＇ anling Group was developed in a fan delta front in a depositional setting of coastal and shallow lake. And the physical properties of the reservoir consisting of non-equal grain size sandstones and gritstones in submerged branch channel are the best, of medium-grained sandstones in mouth bar are secondary, and of siltstones in distal bar are the worst. The heterogeneity of Ⅱ oil group is weak, but the heterogeneity of the other groups is strong. Then different development measures should be adopted based on the distribution characteristics of the sedimentary micro-facies and their differences in reservoir heterogeneity.
