针对鄂尔多斯盆地南部镇泾区块的勘探前景,利用砂岩薄片、铸体薄片和扫描电镜等分析手段对取心并资料进行分析.通过对储层岩石学特征和成岩作用的分析,并结合储层物性的研究成果,采用"多图叠合"的方法有效地预测了研究区成岩相带的展布.对所划分出的4类成岩相特点的分析,提出了成岩相带展布对油气富集具控制作用的观点.为油区进一步勘探提供了科学依据.

In view of the prospects for oil and gas exploration and development in Zhenjing block in southern Ordos Basin,the rock thin sections,cast thin section and SEM are used to analyze the core hole data.According to the analysis and research on the feature of petrology and diagenesis,and combining the research of reservoir physical property,the distribution of diagenetic facies beh in Zhenjing block is effectively predicted with the method of "three charts polymerization".By means of analysis on the feature of four types of diagenetic facies,the idea that distribution of diagenetic facies belt playing control action at oil and gas enrichment is proposed,which provides scientific foundation for the further exploration.
