摘要
低渗透油藏普遍具有低孔、低渗的特点,启动压力梯度和应力敏感对其影响不可忽视。基于此,推导出简化的产能方程,以研究应力敏感和启动压力梯度对低渗透油藏产能的影响。
With low porosity and low permeability, the influence of start-up pressure gradient and stress sensitivity on low permeability oil reservoir is significant. Based on this, the productivity formula that is deduced in this paper with the consideration of start-up pressure gradient and stress sensitive, is order to study the influence of start-up pressure gradient and stress sensitivity on low permeability oil reservoir productivity.
