摘要： 潜水面油藏的形成是多种地质因素共同作用的结果。与常规油藏相比,其主要有油藏动态迁移性、无能、高孔渗、油柱高度大、地质储量巨大、油藏内石油由稠而稀渐变等特征。在后续的构造沉积演化中,经埋藏而形成稠油封堵油藏,此类油藏具有较强的隐蔽性。吐哈盆地七克台油藏就是典型的潜水面油藏,地质条件可类比的盆地应存在类似油藏,因其地质储量巨大,具有良好的勘探价值。

Abstract: A ground water table reservoir is formed by complex processes of multiple geologic factors.Comparing with conventional reservoirs, this kind of reservoir is characterized by dynamic migration, energy-free, high porosity and permeability, high oil column, enormous geologic reserves, and oil varying from heavy to light.In consequent structural and deposit evolution, it tends to shape heavy oil-sealing reservoir with highly hidden nature.Qiketai reservoir in Tuha basin is a typical ground water table reservoir.In analog basins in geologic conditions, there should be similar reservoirs.For the enormous geologic reserves that normally occur, this reservoir has high value for exploration.

Key words: ground water table reservoir, special reservoir, reservoir feature, high porosity, high permeability, heavy oil-sealing reservoir
