|
摘要
本文以高分辨率层序地层学、储层地质学、储层沉积学、测井地质学、开发地质学和开发地震学等相关学科的理论方法为指导,以测井资料为基础,结合地震、录井、岩心等资料,利用深度开发阶段提供的丰富的动态、静态资料,将层次界面分析、沉积过程分析、测井曲线分析等研究手段应用于辽河断陷东部凹陷中段欧利坨子地区沙河街组三段的沉积单元细分与对比、储层沉积特征描述、储层非均质性描述。在S3段地层建立了研究区统一的高分辨率层序地层格架,划分出25个时间地层单元;在时间地层单元内通过相标志的识别和测井相的研究,确立了研究区扇三角洲沉积模式,并对扇三角洲沉积体系内部构成进行了详细的分析研究,总结出7种测井微相模式,利用层序分析法详细剖析了研究区层序地层受构造因素的控制,基准面的升降运动进而影响沉积作用;通过对储层宏观、微观特征进行详细研究,得出储层具有较强的层间、平面、层内非均质性特征;通过储层的全面、系统的研究描述,对其总体特点得出认识后,进行了储层综合评价,评价出较好、中等、较差储层,研究区主要含油层段砂岩组以Ⅲ类储层为主,并编制砂岩组平面综合评价预测等值图,为下一步开发决策提供了优选依据。
The article is theoretically based on high-resolution sequence stratigraphy, reservoir geology, reservoir sedimentology, reservoir well logging geology, exploration geology and exploration seismology etc. On the basis of logging data, combined with seismic, logging and core data, the paper applied both rich dynamic and static data which provided by later stage of exploitation as well as sedimentary process analysis, well logging analysis method on the sedimentary unit subdivision and comparison, reservoir sedimentary and reservoir heterogeneity charaterization of delimitation sand channel bar of middle of the East fault depression of The liaohe fault depression. S3 interval was established the unifying high-resolution sequence formation grid and 25 time-formation unit were classified. Within time-formation unit, the study for sedimentary pattern of regional fan-delta was determined through phase identification and log facies study. Detailed analysis and study were carried on inner part of sedimentary system of regional fan-delta. Seven kinds of logging microfacies pattern were summarized. Through using of sequence analysis, the paper point out that sequence formation in the studied zone was controlled by structural factors, ascending and descending movement of base level further impose influence on seismology; Through intensive study for both macrocosmis and microcosmic features of reservoir, the paper Fig.d out that reservoir has the characteristic of heterogeneous property within interlayer, plane and in situ; Through comprehensive and systemic characterization of the reservoir, the made a reservoir evaluation which classifying reservoir of better、medium and poor, The oil-bearing sand is mainly in medium reservoir, and prediction in sand groups were worked out so as to provide optimization basis for further exploitation strategy.
