摘要
通过岩芯观测、地震解释和测井分析,结合薄片观察、粒度分析以及各种资料的综合分析,对鄂尔多斯盆地南部富县地区上三叠统延长组沉积相类型及特征进行深入研究,提出长9—长6油层组存在砂质碎屑流沉积。结合盆地沉积背景及其演化规律,探讨了砂质碎屑流沉积的成因机制,详细论述了砂质碎屑流沉积的沉积特征,建立了砂质碎屑流的沉积模式。研究表明砂质碎屑流砂体主要由块状粉细砂岩和含泥砾粉细砂岩两种成因相构成,其成因是三角洲前缘砂体在外界触发力作用下,滑动崩塌而形成。分析了砂质碎屑流沉积与油气的分布关系,实践表明砂质碎屑流沉积体是下生上储或下储上生的油藏类型,属于典型的岩性油气藏,构成了该区深水区域的良好岩性圈闭储集体。
According to the analysis for cores,seismic interpretation and well-logging,the authors have thoroughly studied the sedimentary facies types and characters of Yanchang Formation of the Upper Triassic in the south Ordos Basin with thin sections and grain size analysis and a great deal of indoor testing data.The authors have proposed that the sedimentary facies type of Chang 9 to Chang 6 of Yanchang Formation is sandy debris flows.With basin sedimentary and evolutionary background,the genetic mechanism of the sand debris flows have been discussed,and detailed studies have been made on the rock types and sedimentary structures of the sandy debris flows,build up relevant sedimentary models.The results indicate that the sandy debris flows deposit is composed of two genetic facies of massive-bedded siltsand and packsand and mud pebble siltsand and packsand,which indicate deposition from delta-front sand during slip and slump under outside function of energy.Relationship between sandy debris flow depositional systems and distribution of oil and gas are elaborated in detail.It is considered that sandy debris flow deposits are injection migration oil-gas accumulation types and classic lithologic hydrocarbon reservoir,which are the most favorable sedimentary facies belt for the generation of Yanchang Formation reservoirs.
