摘要
准噶尔盆地春风油田主力油层位于N1s—K1不整合面附近,对其层位归属至今仍存争议,层位不同,油气藏类型也大不一样,影响了勘探部署和开发方案的制定。通过地层精细对比、地震层位标定、速度分析、属性提取和地层同位素测年等多种方法的综合分析,该油层与白垩系具有较多的相似性,认为将其划归下白垩统连木沁组较合适。
The major oil layers developing in Chunfeng oilfield are located near the unconformity between Shawan formation and Lower Cre-taceous（N1s-K1）,which membership is still disputed nowadays,thus influencing related exploration deployments and development designs for available different horizons.The comprehensive analyses of them are conducted by means of fine stratigraphic correlation,seismic horizon calibration,velocity analysis,attribute extraction and stratigraphic isotopic dating,etc.and it is shown that the major oil layers are of more similarity with the Cretaceous,and they should be reasonably classified into Lianmuqin formation（K1l） of the Lower Cretaceous.
