Abstract考虑低渗岩心的应力敏感性,通过实验和数值计算,研究了一维水驱油过程中,压力的分布及变化规律,并对其影响因素进行了分析.结果表明:压力分布由于受到应力敏感性的影响而显示出明显的非线性特征,在前缘面处存在一个明显的分界点;应力敏感性程度、黏度比对压力分布的影响较大.
Other AbstractFor low permeability reservoirs, the stress sensitivity cannot be neglected, and it makes the pressure system very complicated. In a low permeability reservoir, an effective system of the displacement pressure is a basis to guarantee the efficient development. Therefore, the research of the characteristics of the pressure distribution in a low permeability reservoir is important to the reservoir development. In this paper, the stress sensitivity of the low permeability core is taken into consideration, and the distribution of the pressure in the process of one-dimensional waterflooding is studied through experiments and numerical calculations, and the factors which affect the pressure distribution are also analyzed. The results show that, due to the effect of stress sensitivity, the pressure distribution sees obvious nonlinear characteristics, and there is an evident demarcation point at the displacing front; the degree of the stress sensitivity and the viscosity ratio have a great influence on the pressure distribution.
