松辽盆地长岭断陷天然气成藏机制及模式研究
|
摘要
随着石油天然气行业的发展,天然气清洁、高效的特点,使其近年来在行业中的比重逐年,吉林油田分公司“油气并举”发展战略的提出,揭开了长岭断陷天然气勘探开发的序幕,在松辽盆地南部,以长深1井为代表的深部营城组探井获得突破,以营城组火山岩为储层的天然气藏成藏机制研究成为深部天然气勘探急需解决的一个重要课题。同时这一课题的完成,还可以丰富断陷盆地油气成藏理论,对相似盆地油气勘探应具指导意义。
本论文主要是针对长岭断陷地质特点和目前勘探中存在的主要问题,从油气来源入手,以油气运移机制、输导通道及储层为重点,对长岭断陷地质特征和油气藏的形成与分布规律有一个明确而深入的认识,为哈尔金构造进一步油气勘探提供可靠的地质保证。
本文以综合地质分析为基础,利用新理论,新方法,新技术,对长岭断陷油气来源,源岩供烃能力,油气运移聚集模式及机制,油气成藏与分布主控因素,成藏期次及模式进行研究,在此基础上,优选油气钻探的有利目标。
取得以下几个方面的成果:(1)长岭断陷沙河子组巨厚的生气层提供了物质基础,生储盖配置关系好,油气成藏条件优越,长岭断陷具备形成大型气田的地质条件。利用天然气成因识别图版分析了天然气成因类型,采用包裹体测试进行了成藏期次研究,结合天然气成藏基本地质条件,综合分析认为断陷缓坡带大型火山岩机构的有利相带形成含气厚度大,产量高的大中型烃类气藏;断陷陡坡带大型火山岩体与深大断裂配置,沟通了深部幔源气,形成大型的二氧化碳富集带。松辽盆地南部深层近洼构造背景下大型火山岩机构有利相带是大中型天然气藏富集区。(3)综合成藏条件研究成果,提出中央隆起带各气藏差异聚集过程,弄清了气藏分布规律,在此基础上预测了有利区带三类5个区带。
As the development of oil and gas industry, the proportion of natural gas has increased year by year for its clean and effective characteristics. Jilin Oilfield Company has put forward the development strategy“oil and gas develop simultaneously”, which lift the curtain on natural gas exploration and development in Changling fault depression. In the southern part of Songliao basin, study on natural gas reservoir forming mechanism becomes an important subject, which urgently needs to solve in deep natural gas exploration with Well Cangshen1 as the representative of exploration wells in deep Yingcheng formation. The completion of this subject could enrich oil and gas reservoir forming of fault basin theory and guide oil and gas exploration in similar basins.
With the importance of hydrocarbon migration mechanism, transporting pathway and reservoir, this paper gave a definite and thorough understanding to geological characteristics of Khaldin structure and oil and gas reservoir forming and distribution according to geological characteristics of Khaldin structure and main problems in recent exploration, which will provide reliable geological guarantee for further oil and gas exploration in Khaldin structure.
This paper got the following results: (1) The thick gas yielding stratum of Shahezi formation of Changling fault depression provide material base with good source-reservoir-cap rock relation and oil and gas reservoir forming conditions, so changling fault depression has the geological conditions to form a large gas field. After analysis, favorable facies belts of volcanic rock in fault depression gentle slope form thick and high yielding large-middle hydrocarbon reservoir. Favorable facies belts of large volcanic rock are the enrichment area of large–middle natural gas reservoirs. (2) We put forward differences of gas reservoirs aggregation process in central uplift belts and made clear distribution rule of gas reservoirs. We predicted favorable zones according to these data.
