为了揭示大牛地气田上古生界山1段至盒3段低孔低渗储层物性差异的主控因素沉积相的作用,采用实验和统计分析相结合的方法,从岩石矿物成分、泥质质量分数、岩石粒度、砂岩厚度等方面综合分析沉积相对储层的控制特征.研究结果表明:最为有利的沉积相为曲流河分流河道相,其次为辫状河分流河道相,再次为三角洲分流河道相,最后为泛滥平原相等.对应物性最好的层段为盒3段,其次为盒2段、盒1段,而山1段、山2段最差.研究结论对于大牛地气田下一步的天然气勘探开发具有一定的参考.

@@@@In order to reveal the Shan 1-He 3 member of the Upper Paleozoic in Daniudi gasfield of low permeability and low porosity reservoir physical property differences of the main controlling factors of the role of sedimentary facies, adopt experiment and the method of combining the statistical analysis, from rock mineral composition, argillaceous quality fraction, rock grain size, sandstone thickness, and other comprehensive analysis sedimentary relative reservoir control characteristics. The results of the study show that the most advantageous sedimentary facies is meandering river by-channel facies, follwed by braided river by-channel facies, then delta by-channel facies, and flood plain at last. And the the best property Corresponding member is He 3 member, followed by He 2, He 1 member, and Shan 1, Shan 2 member is the worst. Research conclusion for daniudi gas field in the next step of natural gas exploration and development has a certain guiding significance.
