摘要(Abstract)：

火山岩岩性、岩相对储层具有明显的控制作用,因此火山岩岩性、岩相研究是后续储层评价的基础。以徐深气田深层火山岩为例,通过"岩心刻度测井",采用"成分+结构"的方法识别岩性,在此基础上,研究"测井—岩性—岩相—亚相"之间对应关系,分析不同相标志的测井响应机理,建立了测井信息与地质相之间的对应关系,确定了爆发相、喷溢相测井特征模式。通过分析有效储层与岩性、岩相关系,明确了有效储层分布规律。研究成果为划分火山岩岩相、亚相提供更丰富的信息,对揭示火山岩时空展布特征、储层预测、井位部署等具有重要意义。
The volcanic lithology and lithofacies possess obvious controlling actions on the reservoir,so the researches on the lithology and lithofacies are the bases of the reservoir evaluation. Taking the deep volcanic rock in Xushen Gas Field as example,by means of the core calibrated well logging and the method of "constituent + structure",the lithology was identified,and based on the stated above,the corresponding relationship of "the well logging-lithology-facies-subfacies"was studied,the response mechanisms of the well logging for different lithofacies markers were analyzed,the correspondences between the logging information and geological lithology were established,and moreover the characteristic modes of the eruption and effusion facies were determined. With the help of the analyzed relationships between the effective reservoir and the lithology as well as the lithofacies,the distribution law of the effective reservoir was made clear. The research results provide richer information for the volcanic facies/subfacies identification and possess important significance for the volcanic space-time spread characteristics,reservoir prediction,well arrangement and so forth.
