Abstract: In the easterm part of North China, igneous rocks are wide-spread in the pre-Tertiary formations, among Which is the lamprophre which is a kind of intrusive diaschistic dyke rock. Well developed with secondary pores formed in the process of diagenesis, it may serve as a good container of oil and gas. It is of great interest to study it as a new type of reservoir. Based on the study of mineral composition and physical properties of lamprophre as a reservoir rock, an adaptive log interpretation model is cons-tructed and completely new computerprocessing programs based primarily on optimization method are used, taking into consideration the influences of environmental factors as well the results of erroneous analyses. The new log interpretation technique enhances the ability of interpreting various complex reservoir rocks including lamprophre. Satisfactory results have been obtained in the application of this technique to several wells.

摘要： 华北东部地区前第三系中广泛发育了各类火成岩,其中煌斑岩是一种侵入的二分脉岩。由于成岩后生作用,它可能具有发育的次生孔隙,从而成为良好的油气层。把它作为一种新类型的储集层来研究是十分有意义的。本文从研究煌斑岩的矿物成分、储层物性出发,建立了相适应的测井解释模型,采用了以最优化方法为核心新的数字处理程序,还考虑了各种环境影响与误差分析。这种测井解释新技术提高了分析复杂岩性包括煌斑岩的能力。通过处理一批井,已得到令人鼓舞的效果。
