【摘要】：本论文依托中国石油吉林油田分公司勘探开发研究院委托新疆大学的研究课题-《英坨地区沉积微相特征及油藏分布规律研究》。松辽盆地正面临开发领域重大战略调整,后备储量资源不足,急需拓展新的接替资源。英坨地区油气显示活跃,具有较大勘探潜力,但沉积特征、油气聚集与成藏规律等方面缺乏统一认识,亟待深入探讨。本文综合采用地震层序地层学、沉积岩石及沉积学、油气成藏地质学等学科的最新研究理论和应用方法和手段,运用地震及各种反演资料,结合钻、录、测、试及岩心分析实验资料,以黑帝庙油层、萨尔图油层、高台子油层及扶余油层为研究重点,通过烃源岩分析、物源分析、沉积微相分析、砂体精细刻画、储层特征分析、区域成藏综合分析和岩性油气藏单砂体及控油分析等手段,研究松辽盆地南部英坨地区油气聚集及成藏规律,并在此基础上:明确泉四段地层沉积物主要受西南方向物源控制,青山口组、姚家组地层主要受西北方向物源控制,嫩三段地层主要受东北方向物源控制;确定高台子和萨尔图地层为辫状河三角洲前缘,扶余地层为曲流河三角洲平原及前缘,黑帝庙地层为深湖及半深湖沉积,席状砂、分流间湾、水下分流河道等微相比较发育;总结出优质砂体与断层及有利的构造背景相匹配是油气富集成藏的主要控制因素;预测了松辽盆地南部英坨地区黑帝庙油层、萨尔图油层、高台子油层、扶余油层的油气勘探有利区带共计14块。本文创新性的提出了优质砂体与有利构造单元相匹配是研究区主要控藏因素这一观点,并明确了英坨地区油气运移主要受隆凹相间的构造格局所影响。
[Abstract]:This paper is based on the study on sedimentary Chinese Tuo - British Petroleum Jilin Oilfield Company exploration and Development Research Institute of Xinjiang University commissioned microfacies and reservoir distribution. The Songliao basin is facing a major strategic adjustment of development, reserve resources, urgent need to expand new resources to succeed. The British Tuo area of oil and gas shows active, has great exploration potential, but the sedimentary features of oil and gas accumulation and accumulation of the lack of unified understanding, to be further discussed. Based on seismic sequence stratigraphy and sedimentology, sedimentary rock, reservoir geology and other disciplines of the latest research on the theory and application of methods and means, the use of seismic and inversion data, combined with drilling that book, measurement, test and experiment data of core analysis, in Heidimiao reservoir, Saertu reservoir, Fuyu reservoir and Gaotaizi reservoir as the research focus, through the analysis of source rocks,. The source analysis, sedimentary facies analysis, fine description of sand body, reservoir characteristic analysis, reservoir comprehensive analysis and lithologic reservoir of single sand body and oil control methods of oil and gas in southern Britain Tuo research accumulation and evolution of Songliao Basin, and on the basis of four strata: clear spring sediments mainly by the southwest provenance control, Qingshankou Formation and Yaojia formation is mainly affected by the northwest provenance control, tender three strata are mainly affected by the Northeast source control; determine the Saertu and Gaotaizi formation is braided river delta front, Fuyu formation is meandering river delta plain and front, Heidimiao for the formation of deep lake and semi deep lake facies, sheet sand and interdistributary bay, underwater distributary channel microfacies development; summed up the high quality sand body and fault and favorable structure background matching is the main control factors of oil and gas enrichment reservoir in southern Songliao Basin; forecast The British Ministry of Tuo area Heidimiao reservoir, Saertu reservoir, Gaotaizi reservoir, Fuyu reservoir favorable zone of oil and gas exploration totaling 14. This paper puts forward the innovation of high quality sand and favorable tectonic units to match the idea that it is the main controlling factor, and the British area of oil and gas the migration is mainly affected by tectonic uplift and concave effect.
