地层的合理划分是沉积相研究的基础,也是储层研究的重要内容。本文以克拉玛依油田五区上乌尔禾组为例,采用测井曲线旋回性对比、基准面旋回对比、相控对比法等方法对洪积扇相地层进行综合对比,对五区上乌尔禾组小层及单砂层的进行了细分对比闭合。通过精细地层划分与对比,可以解决油田开发过程中遇到的许多地质问题,它是油田地质研究的基础性工作。因此,做好精细地层对比,对油田的开发具有重要意义。
The stratigraphic reasonable division is the basis of sedimentary facies research, also is the important content of reservoir research. In this paper, Wuerhe Formation in the five districts of Karamay Oilfield is taken as an example. By contrasting the logging dataset, the reference datum gyration, the phase contrast method and other methods to compare the alluvial fan facies strata, Group of small and single sand layer subdivision contrast closed. Through the fine stratigraphic division and contrast, we can solve many geological problems encountered in the oilfield development process, which is the basic work of oilfield geology research. Therefore, to do fine stratigraphic contrast is of great significance to the development of oilfields.
