这项研究表明，不同的变量，如声波速度，总孔隙度和含水饱和度，和其他次生孔隙度值，可以得到更好的相关性时，处理一个数据库，包括一个岩石类或岩性组。本研究主要以法国、英国等国常用的侏罗纪鲕粒灰岩为研究对象。在约旦的全新世也有少量的样本。总孔隙度分为基质孔隙度和次生孔隙度。利用胶结指数（m），本研究仅强调铸模或洞穴型次生孔隙。不同孔隙度类型与其他测量或推导的属性之间的关系通过外推法和相关性进行了描述。提出了数学公式，以从那些更容易测量的特性中推导出额外的复杂特性。虽然这项研究的结果是基于一个有限的约旦建筑石灰石数据库，他们已经核实。本研究的实际意义及其局限性进行了讨论。
This study shows that a better correlation between different variables such as on sonic velocity, total porosity and water saturation, and other secondary porosity values, can be obtained when dealing with a database, consisting of one petrographic class or Lithological group. This study is based mainly on oolitic limestones of Jurassic age commonly used as building stones in France, Britain and other countries. Few samples have also been taken from Jordan’s Holocene. The total porosity is divided into matrix and secondary porosity. Using the cementation exponent (m), only secondary porosity of the moldic or vuggy type was emphasized in the present study. The relationships between the different porosity types and the other measured or derived properties were delineated, by extrapolation, using correlation. Mathematical formulae were presented to derive additional, complex properties from those more easily measured. Although the findings of this study are based on a limited available database about Jordanian building limestone, they have been verified. Practical implications of the present study and its limitations are also discussed.
