辽河断陷东部凹陷欧利坨子油田沙三段沉积特征研究
|
摘要
欧利坨子油田断裂发育,地质情况复杂,现已进入开发中后期的高含水阶段。本文针对该区实际,以高分辨率层序地层学、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,利用开发阶段老油田密井网提供的丰富的动态、静态资料,将层序界面分析、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欧利坨子油田沙河街组三段的沉积单元细分与对比、沉积特征描述、储层非均质性描述。通过对层序地层、沉积微相与储层物性及含油性分析,得出以下结论:
1.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9种测井微相模式。
2.根据单井、连井沉积相剖面图,结合区域地质背景、砂岩百分含量平面分布图,明确沉积微相在三维空间演化规律。认为研究区以扇三角洲前缘沉积为主,河道砂、河口砂坝为主要储层类型。
3.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砂体的沉积作用;通过储层物性的研究,得出储层具有较强的层间、平面、层内非均质性特征;通过沉积微相与油气分布关系的研究,得出河道砂是最有利的油气储集体,因此可指导加密调整井的部署,为下一步开发决策提供了优选依据。
The Oulituozi oilfield have complex geologic condition with growing faults and now in the intermediary and later stage of high water holdup. 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 dense well spacing in maturing field during 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 characterization of delimitation sand channel bar of the East fault depression of The liaohe fault depression. Four related theories are needed during studying.they are sequence stratigraphy, sedimentary microfacies,physical characteristics of reservoir and oil distribution. There are three essential conclusions as follows.
1. 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. Nine kinds of logging microfacies pattern were summarized.
2. According to the single-well and the peofile of connecting-well,combined with the distributional planar graph of sand content and regional geological,we can make clear the evolution rules at three-dimensional. It is confirmed that the main Sedimentary Environment is fan delta front sedimentation. The main reservoir type is water distributary channels sand and mouth bar..
3. 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; and through study of the relationship beeween sedimentary pattern and oil distribution we can know that channel sand body is the most favorable reservoir, the study would guide us to adjust development of well.so as to provide optimization basis for further exploitation strategy.
