摘要： 总结了目前准噶尔盆地陆梁隆起的不整合研究成果,结合国内外相关资料,对不整合的概念及在控油方面的作用进行了论述,尤其对不整合在成藏中的重要性和与之有关的组合类型进行了剖析,依据资料对准噶尔盆地目前有关不整合的研究提出了看法,认为研究应从不整合面着手,对诸如砂体-不整合面组成的输导系统,断层-不整合面组成的输导系统,砂体-断层-不整合面组成的输导系统及局部不整合与区域不整合的相对关系等问题进行深入研究指出,盆地西北缘,北缘南部及东部地区长期发育着的古隆起是勘探与不整合有关的油气藏最有利的地区,并就解决问题的有效方法进行了归纳,强调了研究工作中的着重点。

Abstract: This paper summarizes the studied results of unconformity in Luliang uplift, Junggar basin, and outlines the conception of unconformity and its effect on oil control, integrated with related information at home and abroad, particularly, including analyses in detail of the significance of unconformity in hydrocarbon accumulation and its types of related combinations. By starting with unconformity research, in-depth analyses of such transport systems as sands-unconformity system, fault-unconformity system, sands-fault-unconformity system and the relationship of local and regional unconformities are made. It is pointed out that the longterm developing uplifts in northwestern margin, south part of northern margin and east part of Junggar basin are the most favorable areas for exploration of oil-gas reservoirs related to the unconformities. In addition, some effective approaches for dealing with these problems are sum up, and related key points are provided in this paper.

Key words: Junggar basin, unconformity, trap, hydrocarbon prospecting
