Abstract
ABSTRACTDrilling and dewaxing are used to manufacture the quantitative model and stochastic model of fracture-vuggy media, respectively, which are used for the investigation on the oil displacement of full diameter cores. The formation and distribution of remaining oil and sensitivity analysis in fracture-vuggy media are studied. The research results show that the density difference between the displacing phase and the displaced phase and the connection position between fractures and vugs determine the fluid distribution law in the vugs. After water flooding, the remaining oil is composed of “attic oil,” “occlusion oil,” “corner oil,” “blind-vug oil,” “oil film,” and “dead oil region.” Then, the influences of oil viscosity, injection rate, density, and viscosity of driving fluid on oil recovery and remaining oil are studied.
