摘要
文章分析了东营北部断裂带中层天然气藏的气体性质、储盖组合类型、温压环境对中层气成藏的影响以及断裂活动对中层气成藏的制约;剖析了三角洲沉积体系在中层天然气成藏中的纽带作用,建立了断裂带中层天然气运聚模式、成藏模式;总结出了中层天然气藏横向分布特征及纵向成藏序列,对于富油盆地断裂带天然气勘探具有很好的指导意义。
This paper analyzes the effect of gas property, reservoir- caprock assemblage, temperature - pressure environment , and faulting movement on forming of gas reservoirs in middle strata in the fault zone of the north of Dongy-ing; dissects the vinculum effect of deltaic depositional system on forming of such reservoirs; establishes migration, accumulation and reservoir forming mode, and summarizes distribution features of such reservoirs. The result of this study may guide gas exploration in fault zones of oil - rich basin.
