摘要/Abstract

摘要： 通过岩心、薄片、常规测井以及 FMI 成像资料多种手段,从火山岩岩性、电性、岩相特征、孔隙类型、储集层物性等方面开展了准噶尔盆地滴西地区石炭系火山岩储集层研究,并进行了火山岩地震相勘探方法及火山岩相平面分布特征研究。分析了火山岩储集层储集空间类型、物性特征以及其影响因素。区内火山岩储集层主要为酸性岩类及火山碎屑岩,孔隙类型为次生孔缝,储集空间为气孔、微裂缝。储集层物性影响因素主要有火山岩的岩性岩相、喷发环境及后期风化淋滤和断裂改造。

Abstract: The reservoir characteristics of Carboniferous volcanic rocks in Dixi area of Junggar basin are analyzed from lithology, electrical property, lithofacies, pore types and reservoir physical property by core, thin section, conventional log and FMI imaging technique, including explorative methods of seismic facies and patterns of lithofacies characteristics for volcanic rocks as well as the pore volume type and affecting factors of the volcanic reservoir. The study shows that the volcanic reservoir rocks compose mainly of acidic rocks and volcanoclastic rocks, with pore types of secondary pores and fissures, vesicular and microfissure reservoir spaces. The main affecting factors to reservoir physical property are lithology, lithofacies, eruptive environment and late-stage erosion, eluviation and fault reconstruction.

Key words: Junggar basin, volcanic rock, reservoir, lithofacies, Carboniferous
