Let students to be familiar with the basic characteristics and formation mechanisms of oil-gas, to grasp the evaluating indexes of source rock, reservoir, seal and oil-gas reservoir, to grasp the styles of source-reservoir-seal association, the features of oil-gas migration, the conditions of forming oil-gas reservoir, the factors of oil-gas reservoir damage and the regularity of oil-gas reservoir formation.

使学员熟悉油气的基本特征及形成机理，掌握生油岩，储集层，盖层及油气藏的评价指标，掌握生储盖组合的型式，油气运移的特点，油气成藏的条件，油气藏破坏的因素及成藏规律。

Through the analysis of oil or gas accumulation conditions of K_1n_2 in Wuerxun depression, this paper points out that there are the differences in organic matter abundance of source rock, the quality space matching relation between caprock and source rock, the lateral seal of faults and oil or gas migration form of K_1n_2 between the south and north of Wuerxun depression.

分析了乌尔逊凹陷南二段油气成藏条件，结果表明：乌尔逊凹陷南二段南北部在源岩有机质丰度、盖源质量空间匹配关系、断层侧向封闭性和油气运移形式上存在着明显的差异性；乌尔逊凹陷北部南一段源岩有机质丰度、南二段和大一段盖源质量空间匹配关系、南二段断层侧向封闭性和油气运移形式均好于南部，导致乌尔逊凹陷北部南二段油气供给、运聚及保存条件均优于南部。这即是造成乌尔逊凹陷北部南二段油气显示好于南部的根本原因

The characteristics of sequence development, source reservoir - seal assemblage and types of hydrocarbon reservoir for each sequence were discussed in detail. The dark colored shale of deep lacustrine facies in the transgressive system tract of SⅡ sequence deposited around the maximum flooding surface is the main source rock in this area. The shale of shallow lacustrine facies in the TST of SⅢ sequence around the MFS is the most important regional seal rock.

结果表明，该区古近系可划分为SⅠ，SⅡ，SⅢ和SⅣ4个层序，分别对应于房身泡组、沙三段、沙一段沙二段和东营组。SⅡ层序水进体系域最大湖泛期沉积的半深湖深湖相暗色泥岩是研究区的主力烃源岩系；SⅢ层序水进体系域最大湖泛面附近的浅湖相泥岩是最重要的区域盖层。

The fan delta, sand beach, sand bars and turbidite fan in the TST of SⅡ and SⅢ sequences are the most favorable exploration targets because of favorable source - reservoir - seal assemblages. Since the high - stand system tract in SⅡ sequence has good source - reservoir assemblage and is covered by the regional seal of SⅢ sequence, the hydrocarbon accumulation in this area is controlled by the local seal rock. The HST of SⅡ sequence becomes the second favorable exploration target zone. Because the scales of the sand bodies of alluvial fan and braided river in low - stand system tract of SⅡ and SⅢ sequences are limited, the formation of a large hydrocarbon accumulation is difficult.

良好的生储盖配置使SⅡ层序、SⅢ层序水进体系域的扇三角洲、滩坝及浊积扇砂体成为本区最佳勘探目标层。SⅡ层序高位体系域生储条件配置好，又有SⅢ层序区域盖层的整体封盖，油气聚集受局部盖层直接控制，可成为较有利的勘探目的层。SⅡ层序、SⅢ层序低位体系域的冲积扇、辫状河砂体体积规模较小，难以形成大油气藏。

Based on an analysis of the relationship between overthrusting and source rock evolution of the foreland basin s in West China, the evolutionary modes of source rocks during o-verthrusting are di.

前陆盆地是世界上油气资源最为丰富的盆地类型之一，而前陆盆地冲断带又是前陆盆地中最主要的油气富集区带之一。

While the organic matters in the carbonate rock and the mud rock are all more than that in Ordovician, especially, source rock thickness of carbonate rock is a suite of very important marine facies source rock in Tarim basin.

而寒武系无论是碳酸盐岩还是泥岩，其有机质丰度均高于奥陶系，尤其是碳酸盐岩烃源岩厚度也较大，因而是塔里木盆地一套十分重要的海相烃源岩。

We have something to do in the new stage.

在这段崭新的时期中，我们有一些要做的。
