摘要: 针对准噶尔盆地不整合实际资料,根据不整合面上、下地层的超一削关系,提出了一种新的不整合类型划分方案。这种方案将不整合划分为四种类型:上超/削性型、整一/削蚀型、上超/整一型、整一/整一型。并且通过对不整合类型与油气运聚关系研究认为:上超/肖嗯性型,不整合面上、下对油气聚集最有利;整一/削独型,不整合面之上有利于油气的运移,不整合面之下有利于油气的聚集;上超/整一型,不整合面之上有利于油气的聚集,不整合面之下有利
于油气的运移;整一/整一型,不整合面上、下对油气运移有利,只有在断层与褶皱的配合下,才有利于油气的聚集。

Abstract: According to the actual unconformity data of Zhuengaer Basin and the relation of lap-erosion on the upper or lower part of unconformity layer, a new kind of unconformity type demarcation project has been put forward. This kind of project has divided the line unconformity as four kinds of types; onlap/erosion truncation type, concordance/erosion truncation type, onlap/con-cordance type, concordance/concordance type. On the basis of research on the relation of unconformity type with oil-gas migra-lion-accumulation,the upper or lower part of onlap/erosion truncation type are best of all favorableness for accumulation of oil and gas; the upper part of concordance/erosion truncation
type are favorableness for migration of oil and gas , the lower part are favorableness for accumulation of oil and gas;the upper part of onlap/concordance type are favorableness for accumulation of oil and gas, the lower part are favorableness for migration of oil and gas; the upper or lower part of concordance/concordance type are favorableness for而gration of oil and gas,and favorableness for accumulation of oil and gas if the match of fault and fold.

Key words: Zhuengaer Basin, unconformity layer, uncon-fortuity type, oil and gas migration, oil and gas accumulation
