摘要
地层划分与对比是地质工作的基础,也是油藏描述最基础的工作之一。一定地质历史时期内,相邻区域的沉积环境和沉积物是相似的,其测井曲线组合特征也应该具有一定的相似性。在缺乏标志层时,这种相似性可作为邻井地层(时间单元)对比的依据。只有根据地质规律划分地层并建立正确的等时对比,才能建立合理的地层格架,揭示储集层非均质性,指导油气田的合理开发。
Reservoir zone division and formation correlation are fundamental works of the geology research,and they are also two of the most basic works in reservoir description.In specific geology period,the sedimentary environment and sedimentary deposit are similar in near area,so the log curve features are also similar.And if there is no formation marker,this similar can be used for isochronous formation correlation between wells.Only rely on correct zone division and isochronous formation correlation,formation framework could be built up.Based on these,we can research the reservoir heterogeneity and guild the reasonable development in oil field.
