摘要:

鄂尔多斯盆地是国内大型内陆坳陷盆地,在延长组富集大量的原油。近年来,随着勘探的深入,在盆地中部的长9油层组发现大量的工业油流,具有较大的勘探潜力,但是油藏分布东西向差异较大。通过对西部和东部2种储层的矿物成分、沉积相类型及砂体分布特征进行对比分析,证明研究区存在2种不同结构的砂体类型:西部砂体单层厚度大,纵向多层叠加,顺物源方向连续性较好,东部砂体单层厚度薄,纵向泥质夹层发育,顺物源方向连续性较差,砂体分布相对孤立。并对2种砂体类型的成因环境进行了分析:西部砂体主要发育在盆地西部的辫状河三角洲沉积体系,在近物源、高能量、物源供给充足的条件下,河流入湖后河道的能量大于湖水的顶托作用,河道继续向前延伸,形成条带状的厚层垂向叠置砂体;东部砂体主要发育在盆地东北曲流河三角洲沉积体系,是在坡缓水浅、远物源、低能量的缓慢沉积条件下,湖水能量和河道入湖能量彼此强弱交替,形成了单层厚度薄且不连续的砂体。

Abstract:

As an important large intracontinental depression sedimentary basin in China,the Ordos Basin has produced quantity of crude oil from Yanchang Formation.Due to the prospective drilling,more and more interests have been paid to the Chang 9 interval of Yanchang Formation in central Ordos Basin in the last few years.Despite of its optimum oil production,there are two types of Chang 9 sandstone reservoirs with distinct variation of sedimentary properties in western or eastern field.The three aspects of sandstone characteristics including mineral components,sedimentary facies,and sandstone distribution features are compared to demonstrate differences of features respectively in western or eastern fields in this paper.The west field is mostly occupied by those sandstones with following characteristics:Large thickness,predominant sands,and vertically continuous distribution.Correspondingly,those sandstones in the eastern field have some characteristics as following:Small thickness,more barrier mud intervals,and relative isolated distribution of sandstones.The variation mechanism is evaluated by conducting factors of sedimentary environment,flowing energy,and channel stability.They are prevailed by the braided river delta environment in the west field,which contrasts to the meandering river delta setting in the east field.The former type of reservoir,which defined sandstones as “high-energy,continuous,stable-course” in this paper,is dominated by shorter transportation,more powerful hydrodynamic energy,steeper slope of lake bottom bed,and more immobile river channel courses through geological sediment period,compared to the latter defined as “low-energy,intermittent,mobile-course” in this paper,of which sandstone bodies are controlled by longer transportation,less hydrodynamic power,gentle gradient slope,and frequent mobile stream courses.

Key words: Ordos Basin, Chang 9 interval, Sandstone features, Forming causes
