【摘要】：近几年松辽盆地深层油气勘探取得了重大进展,发现了多个油气田(藏),主要储层为营城组和火石岭组火山岩及基底火山岩。吉林油区英台断陷于2009年取得勘探发现,2010-2012年多口探井在营城组获得了工业气流,标志着吉林油田火山岩勘探进入了一个新的阶段。但随着气藏认识的逐步深入,有关储层形成机制及分布规律以及储层分类评价方面的研究仍需要进一步深化。本文从火山岩岩性、岩相、火山机构入手,以岩性识别校正为基础,以储层研究为主攻目标,着重总结英台断陷营城组复杂岩性储层分布规律,分析成岩作用对储层发育的控制作用,探索储层形成机制;建立有效储层分类和评价标准,及各类储层的地质-测井识别标志,寻找有利储层分布范围。通过研究,本区营城组一段火山岩存在三种有利储层分布区,一是沿断裂分布的裂缝有利区;二是古凸起/隆起位置的构造有利区;三是凹陷部位的近源有利区。从成岩作用特征平面分布分析,北部火山岩储层要好于中南部,中南部的东侧储层可能最差。营城组二段火山岩有利储层分布为两种,一是沿断裂带分布,其次是古隆起/凸起区。从其主要成岩作用特征来看,北部储层要好于南部,西部好于东部。
[Abstract]:In recent years, great progress has been made in deep oil and gas exploration in Songliao Basin. Several oil and gas fields have been discovered (Zengzao, the main reservoirs are volcanic rocks and basement volcanic rocks of Yingcheng formation and Huoshiling formation). In 2009, the Yingtai fault in Jilin oil area was found to have obtained industrial airflow in Yingcheng formation from 2010 to 2012. The exploration of volcanic rocks in Jilin Oilfield has entered a new stage. However, with the gradual deepening of the understanding of gas reservoirs, The research on reservoir formation mechanism and distribution law and reservoir classification and evaluation need to be further deepened. This paper starts with volcanic lithology, lithofacies and volcanic mechanism, based on lithologic identification and correction, and takes reservoir research as the main target. The distribution law of complex lithologic reservoirs of Yingcheng formation in Yingtai fault depression is summarized, the control of diagenesis on reservoir development is analyzed, the formation mechanism of reservoirs is explored, and effective reservoir classification and evaluation criteria are established. Through the research, there are three favorable reservoir distribution areas in the first member of Yingcheng formation, one is the favorable area of fracture distribution along the fault; The second is the tectonic favorable area in the paleouplift / uplift position, and the third is the near source favorable area in the depression. According to the plane distribution of diagenesis characteristics, the volcanic reservoir in the north is better than that in the central and southern part. The eastern side of the central and southern part of the reservoir is probably the worst. There are two favorable volcanic reservoirs in the second member of Yingcheng formation, one is along the fault zone, the other is the paleouplift / uplift area. From the main diagenesis characteristics, the northern reservoir is better than the southern one. The west is better than the east.
