克拉美丽气田石炭系火山岩体识别及内幕结构解剖——以滴西18井区为例
|
摘要
克拉美丽气田火山岩由岛弧环境强火山喷发形成,火山岩与沉积岩交互,发育盾状、锥状及复合状等多种火山机构类型,涵盖中性、基性、酸性等多种火山岩成分。以"源控"理论为指导,地质、测井、地震与生产动态相结合,开展了火山口、火山通道、火山机构及火山岩体的逐级识别与解剖技术研究,确定气田火山岩体分布及内幕结构,为开发方案的部署提供了依据。
Volcanic rocks in Kelameili gas field came from powerful island-arc volcanic eruption and were interbedded with sedi-mentary rocks.Rocks appears various forms of volcanic edifice such as lava shield,coniform and combination shapes,and covers neutral,basic and acidic composition.Based on the theory of "hydrocarbon-source control",referring to geology,well logging,seismos and production performance information,the study on recognition and analysis of crater,volcanic conduit,volcanic edifice and volcanic massif was conducted.The configuration and inner structure of volcanic massif in gas field was determined,contributing to exploitation program preparation.
