低渗透裂缝性潜山稠油油藏物理模拟实验研究
Physical simulation experimental study on low-permeability buried-hill fractured heavy oil reservoir
摘要
Abstract
In order to understand the percolation mechanism and development regulation in low-permeability buried-hill fractured heavy oil reservoir,similarity criteria of physical simulation on water flooding and hot water flooding in the fractured reservoirs was established by using similarity theory and flow theory.Taking a low-permeability buried-hill fractured heavy oil reservoir in Bohai Sea as an example,a large scale physical model (1 m× 1 m×0.5 m),as analogy of the objective reservoir,was designed to simulate the water flooding experiment in different well patterns and development modes.Analysis results on oil production,water production and water-oil saturation in experiment show that:the stereoscopic horizontal well pattern can give full play to the function of oil-water gravitational differentiation and reduce the rising rate of water cut in the buried-hill reservoir.The staggered well pattern can increase the sweep efficiency of the injected water by increasing the injector-producer distance.Effect of the hot water flooding becomes worse as the injector-producer distance increases.The addition of surfactants into the injected water can increase the oil displacement efficiency in the fracture and lower the imbibition effect and matrix contribution rate.关键词
