基于数理统计学的测井曲线标准化方法研究

Method Study on Standardization of Logging Curves Based on Mathematical Statistics

石油勘探的测井曲线标准化是区域多井评价的关键,是地球物理解释和反演工作的基础,也是油藏描述和精细地质研究的重要内容。测井曲线标准化技术方法是因测井仪器多样化、测井环境多元化、技术多元化、操作人员技术水平多样化等而变得很复杂。运用数理统计的描述性数理统计与推论性统计两大理论的趋势分析与拟合回归分析的技术方法,进行测井曲线标准化方法研究取得了良好的成果。

Logging curves standardization in petroleum exploration is the key to regional multi well evaluation,is the basis of geophys- ical interpretation and inversion.h is also an important part of reservoir description and meticulous geological research. The stan- dardization of logging curves is due to the diversification of logging instruments, diversification of logging environment, technology diversification,Diversification of operators＂ technical level etc. And become very complicated. Using mathematical statistics two ma- jor theories of descriptive statistics and inferential statistics, technical method of trend analysis and fitting regression.This method of logging curve of standard research and achieved good results.
