Abstract

Abstract

To find out the mechanism and controlling factors of the original lentoid sand reservoir, its oil-trapping process is numerically simulated on one dimensional condition based on the theory of two-phase fluid flow in compactable porous media, taking into account of its various related processes and parameters. It is ascertained that overpressure is the force of gross fluid flow out of the source rock rather than the force of oil accumulation in the lentoid sand reservoir. The fundamental force for oil accumulation in the lentoid sand reservoir is the difference of capillary pressures built up between the source rock and the reservoir. The potential of oil phase in lentoid sand reservoir is less than that in the surrounding source rock in the oiltrapping process. The oil trapping process of lentoid sand reservoir is controlled by the principles of potential balance and volume balance. The oil-bearing characteristics of the reservoir are determined by the oil volume provided and the oil phase potential difference between the source rock and the reservoir.
