摘　　要：针对克拉玛依油田六区、七区、九区上盘石炭系火山岩内幕油藏成藏规律认识不清的问题,运用油气成藏要素配置关系分析方法,通过烃源岩评价、储集空间类型及组合方式识别、储盖组合、油气输导体系及成藏模式分析,揭示火山岩内幕成藏规律。结果表明:该区上盘石炭系火山岩内幕油源充足;裂缝-孔隙型和裂缝型储层是最有效的储集空间组合类型,储层物性属中孔低渗储层,火山岩内幕有利储层主要分布在主干断层附近;盖层为致密的火山岩隔层或致密沉积岩;圈闭类型多样;油气输导体系主要由同沉积主干断裂构成;石炭系内幕油气成藏模式为新生古储,油气主要聚集于主干断层附近石炭系内幕各种有利圈闭内。研究成果对该区石炭系内幕火山岩油气勘探和评价具有较好的借鉴和指导意义。The configuration relationship of key hydrocarbon accumulation factors was analyzed to understanding the Carboniferous volcanic inside hydrocarbon accumulation patterns in the upper 6th,7th and 9th districts of Karamay Oilfield.The volcanic inside hydrocarbon accumulation patterns were revealed by source-rock evaluation,reservoir space type,combining identification,reservoir-cap combination,hydrocarbon migration system and hydrocarbon accumulation pattern.Result indicates that the fracture-pore and fractured reservoirs are considered as the most favorable reservoir space combination with medium porosity and low permeability.The favorable volcanic inside reservoir mainly distributes near the major faults.The cap-rock is a tight volcanic barrier or a tight sedimentary rock.There are multiple types of traps in this area.The hydrocarbon migration system mainly includes the major sedimentary faults.The Carboniferous reservoir is considered as a hydrocarbon accumulation pattern with new source-rock and ancient reservoir.The hydrocarbon mainly accumulates in various favorable traps inside the Carboniferous near the major faults.This research could provide certain reference and guidance to the Carboniferous inside volcanic hydrocarbon exploration and evaluation in this area.
