克拉玛依油田六中区克上组流动单元研究

克拉玛依油田六中区克上组为一断块油藏，砂砾岩储层非均质性严重, 针对该区冲积扇～扇三角洲相砂体的组合特点及分层对比方案，通过应用孔隙几何学方法及流动带指标，对克上组储层进行了流动单元分类与评价，解决了储层评价的难题。该区流动单元分布特征明显有别于河流相和三角洲相流动单元分布的一般特征，工区发育Ⅰ类、Ⅱ类、Ⅲ类、Ⅳ类和Ⅴ类流动单元，各类流动单元呈现渐变拼接关系，各类流动单元依次出现。高级别流动单元主要分布在工区中部，工区西南部和工区南部的流动单元级别相对较低。流动单元研究成果对油藏滚动勘探开发有较强的指导意义。

THE FLOW UNITS IN KESHANG FORMATION,LIUZHONG AREA,KARAMAYI OILFIELD

Keshang formation, Liuzhong area, Karamay oilfield is a fault block oil reservoir with serious heterogeneity in the sandstone and conglomerate reservoirs, aimed at the association characteristics and the layerdividing and correlation scheme of alluvial fanfan delta sandbodies in the area, as well as by applying pore geometry and flow zone index, the classification and evaluation of the flow units units in Keshang formation are carried out, and the difficulty of reservoir evaluation is solved. The flow unit characteristics in the area are distinctly different from the ones in alluvial facies and delta facies, in the research area, there are developed typeⅠ, Ⅱ, Ⅲ, Ⅳand Ⅴflow units, among them, there is a gradual change and splicing relation, the units occur in turn. The highgrade flow unit mainly exists in the middle part of the area, and the flow units in southwest and south parts of the area are relatively lowergraded. The research results of flow units can guide progressive exploration and exploitation.
