摘要
基于定容封闭未饱和油藏的物质平衡方程式,本文提出了压降法(在直角坐标纸上P_R与N_pB_O的关系法)和诺模图(在双对数坐标纸上ΔP_D与N_pB_o的关系图)。这些方法的应用,可以确定未饱和油藏的原始地质储量和判断驱动类型。
<ABSTRACT> Based on the material balance equation of a closed unsaturated oil
reservoir with a fixed volumn, this paper presents a pressure drop method (the
relationship of PR versus NpB0 on Cartesian coordiuates) and a uomograph (the
plot of PD versus NpBo on logarithmic coordinates) .Thus the initial geological
reserves of an unsaturated reservoir and its drivetype can be determined by applying
these methods.
