摘要
围绕塔北西部碳酸盐岩和碎屑岩这两大类勘探目标,采用"成因分类法"将塔北西部已经发现的圈闭划分为4大类8亚类。在此基础上,对不同圈闭类型分布的主要层位及平面展布特征做了分析。划分了4个圈闭形成期,并分析了在不同构造演化阶段,构造运动和沉积环境对不同圈闭类型的控制作用。归纳了塔北西部圈闭的空间组合规律。
Based on ＂Genetic Classification＂ theory, the traps discoveried in the west Tabei uplift are classified into four types and eight sub types in the carbonate strata and the clastic strata which are two kinds of exploration goals. Different trap types lay in different formations and different areas, and the distributional characteristics are researched. Four trap formation stages are divided, and how the structural movements and sediment entironments control the formation of different trap types are analyzed. The law of trap spatial combination is summarized.
