| 摘 要： | 三塘湖盆地石炭系卡拉岗组火山岩岩性揭示该区火山岩岩相主要包括火山爆发相、溢流相,火山沉积相不发育。为了明确不同岩相分布规律,本文系统利用测井、地质、地震等多种资料,建立测井岩性识别模板,以单井相作为约束,开展地震反演,明确火山岩岩相的平面分布规律。研究结果表明:该区火山喷发方式以裂隙式为主,火山口呈串珠状沿主断裂排列;溢流相平面呈层状分布,溢流相安山岩最为发育。研究结果可有效指导该区火山岩油藏的勘探评价工作,同时为火山岩岩相研究提供可借鉴的研究思路。

| Abstract: | Volcanic lithofacies of Kalagang Formation in Santanghu Basin mainly consisted of volcanic explosive facies and effusive facies, yet volcano-sedimentary facies was poorly found. By using of wireline logging, geology and seismic data, logging response pattern for volcanic lithology identification was built, and then seismic inversion was runned restricted by the single-well facies in order to make clear of the areal distribution of volcanic lithofacies. The research results revealed that the main type of volcanic eruption was crevice eruption and crater was arrayed heatedly along the basement faults; effusive facies that mainly consisted of andesite was spreaded like bedded. The results can effectively guide the exploration and evaluation for the volcanics of Kalagang Formation, and also provide the idea of the research can be used as a reference of volcano rock facies. |
