摘要 层序地层学提供了一种精细的沉积相分析方法,它从地层成因研究入手,通过等时地层的对比与分析,有效地解决了同一时期相在横向上的变化与展布,为储集体的预测和隐蔽油气藏的勘探提供了方法保证。本文针对研究区油气藏发育较为隐蔽的特点,在研究中以层序地层学的原理与方法为指导,运用测井与3-D成像技术,对地下生储盖时空分布规律进行了有效预测,并成功地发现了多条含油古河道砂体,为研究区隐蔽油气藏的勘探指明了方向。 Sequence stratigraphy makes it possible to analyze sedimentology meticulously. Beginning with reservoir genesis study,sequence stratigraphy solves the problem of latera1 variation and distribution of the sedimentary facies within a same period of time through stratigraphic corre1ation and analysis, which provide ensurance in terms of methodology for the prediction of the reservoir body and the exploration of subtle hydrocar bon reservoir. In view of the fact that the hydrocarbon reservoir in the study area was developed in a subtle manner,this paper utilizes logging and 3-D imaging techniques under the guidance of the principles and methodologies of sequence stratigraphy. Effective prediction has been done for the distribution of source rocks, reservoir and cap rocks in terms of time and space. Many oil bearing paleo channel sandbodies were discovered which show the potential for the exploration of subt1e hydrocarbon reservoirs in the area.
