利用地表露头及地震剖面等资料,综合分析了准噶尔盆地南缘中段燕山期构造层侏罗系和白垩系的不整合结构类型及其分布;根据不整合面上下岩性及其组合形式,总结了燕山期构造层不整合面的继承性和迁移性.燕山期不整合面的叠置与附近的断裂不但构成了区域性的空间运移通道,而且为油气提供了良好的聚集场所.
利用地錶露頭及地震剖麵等資料,綜閤分析瞭準噶爾盆地南緣中段燕山期構造層侏囉繫和白堊繫的不整閤結構類型及其分佈;根據不整閤麵上下巖性及其組閤形式,總結瞭燕山期構造層不整閤麵的繼承性和遷移性.燕山期不整閤麵的疊置與附近的斷裂不但構成瞭區域性的空間運移通道,而且為油氣提供瞭良好的聚集場所.

Unconformity type and distribution of Yanshanian structural system are studied in the Midst of Southern Junggar Basin through seismic profile and outcrop.The succession and migration of unconformity are analyzed by rock types and assemblage above and below unconformity.The unconformity and faults in Yanshanian structural system are not only the important paths for the oil and gas migration,but also are the favourite place for the oil and gas accumulation.
