摘要： 三叠系是吐哈盆地油气勘探的重要层系, 1996年以来将鲁克沁三叠系油层改归中三叠统克拉玛依组。以陆相盆地构造和气候的周期性变化控制层序地层为立足点,结合地震和钻、测井信息,分析了区域地层横向变化规律,探讨了地层测井响应的内在机理。认为,小泉沟群内部区域性的不整合是划分中、上三叠统的自然界线,再次将鲁克沁三叠系油层时代还原为晚三叠世。

Abstract: Triassic system is a major sequence for petroleum exploration in Tu-Ha basin. Since 1996, the Triassic pay zone in Lukeqin area has been classified into Karamay formation of Middle Triassic from Late Triassic. In this paper, the Middle Triassic payzone is reclassified back to. original Late Triassic,based on the view point that continental basin structure and climate cyclic changes could control the sequence strati-graphic formations, integrated with the seismic, drilling and well log information as well as analysis of lateral changes of regional strata. Also, the reclassification is supported by inherent mechanism of the well log responses and recognition of the regional unconformity in Xiaoquangou group as a natural dividing line betw een Middle Triassic and Upper Triassic in southern Tu-Ha basin.

Key words: Tu-Ha basin, Triassic, strata correlation, self-potential, resistivity
