前言近几年来,一些学者假设地层水穿过油气藏向上流动而不考虑其流动机理(Cordell,1973,Hunt 1979,Neglia1979)。图1说明了这种假说的水流动途径。然而这种假设已被普通的地下水力学所批判(Chapman 1974,1980)。这些批判的根据是:水流向上流出油藏背斜顶部以外既要比盖层岩石中的水有更大的位能(每单位质量能量),又要比上覆储集层或水层的水有更大的位能。如果我们要了解生油层的石油与油气藏石油之间的关系,那么必须正确了解生油层与油藏之间岩石中水可能的流动途径。在运移过程
In recent years, some scholars have assumed that formation water flows upward through reservoirs irrespective of its flow mechanism (Cordell, 1973, Hunt 1979, Neglia 1979). Figure 1 illustrates the water flow path for this hypothesis. However, this assumption has been criticized by ordinary groundwater mechanics (Chapman 1974, 1980). The rationale behind these critiques is that water flow upwards out of the top of the reservoir anticline must have both greater potential energy (per unit mass energy) than water in the cap rock, and more water than the water overlying the reservoir or water layer There is a greater bit of energy. If we are to understand the relationship between the oil in the reservoir and the oil in the reservoir, we must correctly understand the possible flow of water in the rock between the reservoir and the reservoir.
