新疆塔里木盆地艾协克-桑塔木油气区带圈闭类型及空间组合规律

RULES OF TRAP TYPES AND SPACE ASSEMBLAGES IN THE AIXIEKE-SANGTAMU HYDROCARBON ZONE OF THE TARIM BASIN, XINJIANG

艾－ 桑区带内各种类型的圈闭较发育，主要的圈闭类型有断背斜、断块潜山、盐底辟背斜、低幅度挤压背斜和非构造圈闭，其中与盐体有关的圈闭占有重要的地位。海西晚期、印支－ 燕山期和喜山期的构造运动在区带内形成了一系列圈闭，其中，在奥陶系。

In the Ai-Sang zone, traps of various types are well developed. Main trap types include fault anticlines, block buried hills, salt diapirism anticlines, low extent compressive anticlines and nontectonic traps. Among them, the traps related to rock body occupy an important position. The Late Hercynian, the Indosinian-Yanshanian and the Himalayan tectonic movements formed a series of traps in the zone. And significant breakthroughs in petroleum have obtained in the Ordovician, the Carboniferous and the Triassic traps.
