| 摘 要： | 黄骅坳陷唐家河油田古近系沙河街组为水下重力流水道沉积，可划分为3个微相，即水道中心微相、水道侧缘微相和水道间微相。砂体在平面上呈条带状，条带宽度一般为100500 m，厚度一般为210 m。根据储层质量的差异性，重力流水道沉积的储层质量可分为4类，各类储层具有不同的岩性、物性及产能特征。断层、砂体及储层质量的差异分布形成了复杂的构造－岩性圈闭，其中，断层与条带状砂体斜交，导致圈闭规模小。其内储层质量的差异分布及复杂的油水关系，则导致离散、零星的含油分布。这一储层定量模式及油层差异分布模式对重力流水道沉积的油气勘探和开发具有较大的指导意义。

| Abstract: | Sediments of subaqueous gravity flow channel were developed in the Shahejie Formation of Paleogene in Tangjiahe Oilfield, Huanghua Depression. Three microfacies can be identified as channel center, channel margin and inter-channel. The sandbody is ribbon-shaped, generally 100500 m wide, and 210 m thick. According to the differences of reservoir quality, gravity flow channel can be classified as four kinds. Each kind of reservoir shows different lithology, property, and production capacity. The distribution variation of faults, sandbodies and reservoir quality formed the complex structural-lithologic traps. Faults are crossed slantways with ribbon sandbody, resulting in small-scaled traps. Differential distribution of reservoir quality and complex oil-water relation form discrete and bitted oil pools. The quantitative reservoir model and differential distribution model of oil-bearing strata have great significance in the oil and gas exploration of gravity flow channel sediments. |
