鄂尔多斯盆地延长组深层石油成藏规律

Deep petroleum accumulation law of Yanchang Formation in Ordos Basin

鄂尔多斯盆地的三叠系延长组长6储层作为该区域内主要油层,经过多年的勘探开发,产量逐渐降低,且随着社会经济的发展,石油的需求量日益增大,原有的开发量以及无法满足社会的需求,勘探开发新的含油系和含油区对缓解能源危机是非常有必要的。鄂尔多斯盆地晚三叠世延长组沉积阶段经历了三次湖侵期,进而相应形成了三套非常关键的烃源岩。本文主要介绍了鄂尔多斯盆地延长组深层石油的分布规律,找出该区域内的有利的预探区,为进一步勘探开发提供有效的理论依据。

Ordos basin Triassic Chang6reservoir as the main reservoir in the area,after years of exploration and development,gradually reduce production,and with the development of social economy,the demand for oil is increasing,the development of the original volume and can not meet the needs of society,the exploration and development of new oil and oil area is very it is necessary to alleviate the energy crisis.The three stage of the Late Triassic Yanchang Formation in Ordos Basin has experienced a period of Lake invasion in the late three,and then formed a set of very important hydrocarbon source rocks.In this paper,the distribution law of deep oil in Yanchang Formation of Ordos Basin is introduced,and the favorable exploration area is found out,which provides an effective theoretical basis for further exploration and development.
