摘要:

叠合盆地深层油气运聚机理是油气勘探必须解决的关键科学问题之一。选择代表性的储层介质进行系统的油气运聚作用分析能为解决这一关键科学问题提供范例。克拉美丽天然气藏是中国西部典型的火山岩气藏,对其天然气充注过程和充注路径有待深入研究。通过系统的天然气地球化学资料分析,认为克拉美丽气田的天然气来源单一,主要为煤型干酪根降解气。但是,天然气的成熟度在气田的东西部存在差异:东部成熟度较高,西部成熟度较低。运移示踪分析表明,天然气主要沿2条断层运移,来源于西部滴水泉凹陷的天然气沿滴北断层向东运移,而来源于五彩湾凹陷的高成熟度天然气沿滴水泉断层向西运移,两者在克拉美丽鼻状构造的中部DX18井区混合,导致该区天然气同位素的倒转。分析表明断层活动改变了火山岩的储层,沿断裂带形成了裂缝型储层,并在滴水泉断层和滴北断层夹持的鼻装构造上形成了裂缝—孔隙型储层,储层的渗透率相对于火山岩的基质储层提高了2~3个数量级,是导致天然气沿断裂带发生侧向运移的关键地质条件。同时,源自五彩湾凹陷的天然气表现出自构造高部位向构造低部位倒灌的现象,这是后期东部克拉美丽山的隆起所造成的构造东西方向的翘倾作用产生的假象。油气运移方向和主输导通道的识别和重建,启发准噶尔盆地火山岩油气勘探宜围绕主生烃凹陷,沿断裂带及其所控制的优质储层展开,为油气勘探指明了方向。

Abstract:

The Kelameili natural gas field is the only gas reservoir that developed in the volcanic reservoir in the Junggar Basin,northwest China.Geochemical characteristics indicate that the natural gas was sourced from type Ⅲ kerogen developed in the Wucaiwan Sag to the east and the Dishuiquan Sag to the west,respectively.The maturity of the natural gas from the Dishuiquan Sag was lower than that from the Wucaiwan Sag.Lateral variation of the composition,maturity,and isotopes of the natural gas indicate that the main pathway system for the natural gas lateral migration is the EWstriking fault that developed in this district.Natural gas from the Dishuiquan Sag migrates eastward and that from the Wucaiwan migrates westward.Mixing happened at well DX18 district and isotope reversal was observed in this district.Research indicates that fissure and fracture due to latestage tectonic faulting have enhanced the capability of the reservoir.The permeability of the reservoir has enhanced 23 orders higher than that of the background,which in turn makes the faults to be the best hydrocarbon migration pathway systems.The above recognized hydrocarbon migration pathway systems indicate that the hydrocarbon exploration should focus on the traps that have been linked by the faults with the source kitchens.

Key words: Fault, Hydrocarbon migration, Volcanic gas reservoir, Kelameili Gasfield, Junggar Basin
