摘要: 通过对孔-深关系曲线的特征和数学表达式进行研究,发现孔-深关系曲线可以分成指数递减阶段和常数孔隙度阶段。传统的孔-深关系方程只能描述指数递减阶段的孔隙度变化。现给出了一个新的统-的孔-深关系方程,它能同时描述指数递减阶段和常数阶段的孔隙度变化,因而,也能更好地服务于盆地模拟和石油地质研究工作。

关键词: 孔隙度, 埋藏深度, 曲线, 方程

Abstract: Based on a study conducted on characteristics of the porosity-depth curve and its mathematic expression, it is discovered that the curve could be divided into two stages, namely an exponential decline stage and a constant stage. The earlier traditional porosity-depth curve can only be used to describe the variation of porosity in exponential decline stage. The newly-suggested unified porosity-depth equation can be used to describe the variation of porosity simultaneously both in exponential decline stage and in constant stage too. Consequently, the new equation will serve better in the research work of basin simulation and petroleum geology.

Key words: porosity, burial depth, curve, equation
