在一个沉积盆地的岩相分析中,还可以用自然电位曲线配合电阻曲线来研究单井纵向层序,建立时间概念和划分纵向相序,了解在地质时期中它的沉积环境变迁。同时,通过同一时期井组的曲线研究可以追踪横向相变,了解横向沉积环境的变迁。 瓦特(Walther)相律指明,一个地点的纵向相序是由横向分布的沉积环境模式经过一段时间水平迁移而形成的。这是以恢复古环境为主要研究内容的成因地层学的一个极其
In a sedimentary basin lithofacies analysis, we can also use the natural potential curve with the resistance curve to study the single well longitudinal sequence, establish the concept of time and divide the vertical phase sequence, and understand its sedimentary environment change in geological period. At the same time, the curve studies of well groups in the same period can trace the lateral phase transition and understand the changes of the horizontal depositional environment. The Walther law states that the longitudinal phase sequence of a site is formed by horizontal migration of sedimentary environment patterns over time. This is an extremely important study of the genesis of the origin of the restoration of paleoenvironment
