摘要：

依据各沉积相的平面分布形态,将沉积相划分为扇形沉积相带、席状沉积相带和条带状沉积相带,并分别对不同类型的沉积相带采取不同的缓冲方法,再依据瓦尔特相律,对空间上已知沉积相类型的井进行分析,最终做到利用计算机辅助或代替人工的工作,根据已知单井沉积相的类型而自动进行平面沉积相的研究。将这种方法应用于大港油田孔南地区孔二段时期的沉积相研究中,证明了此方法的可行性。

Abstract:

In this paper, the sedimentary facies are grouped into fanshaped sedimentary facies, sheet sedimentary facies and banded sedimentary facies based on the plane distribution patterns of sedimentary facies, and different buffer zone methods are used for different types of sedimentary facies. Based on the Walther’s law of facies, we have analyzed the wells of known sedimentary facies types. Moreover, we have carried out the automatic analysis of the plane sedimentary facies for the wells with known sedimentary facies types by using computeraided programming and replacement of manual works. The feasibility of this method was proved by the study of the sedimentary facies of K2 member in the Kongnan area of Dagang Oilfield.
