【摘要】：近幾年松遼盆地深層油氣勘探取得了重大進(jìn)展,發(fā)現(xiàn)了多個(gè)油氣田(藏),主要儲(chǔ)層為營(yíng)城組和火石嶺組火山巖及基底火山巖。吉林油區(qū)英臺(tái)斷陷于2009年取得勘探發(fā)現(xiàn),2010-2012年多口探井在營(yíng)城組獲得了工業(yè)氣流,標(biāo)志著吉林油田火山巖勘探進(jìn)入了一個(gè)新的階段。但隨著氣藏認(rèn)識(shí)的逐步深入,有關(guān)儲(chǔ)層形成機(jī)制及分布規(guī)律以及儲(chǔ)層分類評(píng)價(jià)方面的研究仍需要進(jìn)一步深化。本文從火山巖巖性、巖相、火山機(jī)構(gòu)入手,以巖性識(shí)別校正為基礎(chǔ),以儲(chǔ)層研究為主攻目標(biāo),著重總結(jié)英臺(tái)斷陷營(yíng)城組復(fù)雜巖性儲(chǔ)層分布規(guī)律,分析成巖作用對(duì)儲(chǔ)層發(fā)育的控制作用,探索儲(chǔ)層形成機(jī)制;建立有效儲(chǔ)層分類和評(píng)價(jià)標(biāo)準(zhǔn),及各類儲(chǔ)層的地質(zhì)-測(cè)井識(shí)別標(biāo)志,尋找有利儲(chǔ)層分布范圍。通過研究,本區(qū)營(yíng)城組一段火山巖存在三種有利儲(chǔ)層分布區(qū),一是沿?cái)嗔逊植嫉牧芽p有利區(qū);二是古凸起/隆起位置的構(gòu)造有利區(qū);三是凹陷部位的近源有利區(qū)。從成巖作用特征平面分布分析,北部火山巖儲(chǔ)層要好于中南部,中南部的東側(cè)儲(chǔ)層可能最差。營(yíng)城組二段火山巖有利儲(chǔ)層分布為兩種,一是沿?cái)嗔褞Х植?其次是古隆起/凸起區(qū)。從其主要成巖作用特征來看,北部?jī)?chǔ)層要好于南部,西部好于東部。
[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.
