【摘要】 为了解决研究区目前存在的地质问题,应用层序地层学理论、沉积学理论为指导,充分利用岩心、测井及地震资料,对乌南次凹南屯组进行层序地层学综合研究,在层序划分的基础上,建立层序地层格架;并通过大量岩心观察描述,结合地震、测井、录井资料对沉积相的空间展布规律进行研究。同时,应用石油地质学理论,对南屯组成藏条件进行分析,并对有利砂体的分布范围进行预测,这将为隐蔽油气藏综合评价和预测勘探提供重要的依据。更多还原

【Abstract】 In order to solve the existing geological problems,The essay based on the recent theory and method of Sequence Stratigraphy,Seismic Stratigraphy and Sedimentology,according to observe large numbers of cores,uses seismic,logging and core information to analyze and research the sequence characteristics,formation framework and sedimentary facie in NanTun Group in Southern Area of WuErxun Hollow.Moreover,combined with structural geology feature of Wunan in WuErxun Hollow,we searched on the characteristics of the sequence and prediceted the distributiong area of favorable facie body.This will cover evaluation and predicition of oil and gas reservoirs provide an importantant basisfor exploration.更多还原
