摘要/Abstract

摘要： 准噶尔盆地油气发现程度差别大，天然气探明率较低。石炭系火山岩是盆地内目前天然气储量最多的层系，勘探证实其天然气成藏特征非常复杂。依据盆地内克拉美丽气田、五彩湾气田、阜康凹陷、滴北凸起等地区井的岩心、薄片鉴定及分析化验数据，在重点研究主力烃源岩松喀尔苏组b 段特征的基础上，结合盆地内火山岩储层特征及天然气来源，分析石炭系火山岩天然气的成藏特征及勘探潜力。结果表明：石炭系烃源岩在五彩湾凹陷、滴水泉凹陷及东道海子凹陷等地区广泛分布，其中泥岩有机碳含量平均为1.58%；石炭系烃源岩有机质类型以Ⅲ型为主，大部分达到高成熟阶段，且火山活动增加了有机质的生烃能力。优质储集体以爆发相和溢流相为主，孔隙和裂缝发育，与上覆二叠系或石炭系内部致密层段形成良好的储盖组合，靠近凹陷深部地区具备形成规模气藏的成藏条件，滴南凸起、滴北凸起、北三台凸起和车拐地区具有较大勘探潜力。

Abstract: The degree of oil and gas discovery varies greatly in Junggar Basin and the proven rate of natural gas is low. Till now, the Carboniferous volcanic rock has the largest natural gas reserves of the basin, however, it shows complex gas accumulation characteristics indicated by exploration practice. Based on the core, thin section observation and lab test data of wells in Kelameili Gas Field, Wucaiwan Gas fi eld, Fukang Sag and Dibei Bulge, characteristics of the main source rocks of section b of Songkalsu Formation are studied, and the gas accumulation characteristics and exploration potential of the Carboniferous volcanic rocks are analyzed by combining with the studies on reservoir properties and gas sources. The results show that the source rocks of the Carboniferous are widely deposited in Wucaiwan Sag, Dishuiquan Bulge and Dongdaohaizi Sag, with an average TOC of 1.58%, organic matter type of mainly Type Ⅲ, and mostly in high mature stage.In addition, volcanic activity has promoted the hydrocarbon generation capacity of organic matter. High quality reservoirs are dominated by volcanic rocks of explosive and overfl ow facies, with pores and fractures developed, forming a good reservoir-caprock assemblage with the overlying the Permian or internal the Carboniferous tight layers. The gas accumulation conditions in the deep sag area are favorable for forming largescale gas reservoirs. The exploration potential is promising in Dinan Bulge, Dibei Bulge, Beisantai Bulge and Cheguai area.
