摘要

dc指数法是一种常规的地层压力检测方法。在该方法中,建立合理的正常趋势线是成功的关键。本文通过对dc指数正常趋势线方程的数理统计分析,得出同一地区的不同井dc指数正常趋势线具有相近斜率不同截距的结论。并重新分析了dc指数的概念,对dc指数及其正常趋势线方程的特征进行了解释、分析结果有助于更好地进行地层压力解释。

Abstract

Determine reasonab1e pore pressure tendency is a key to detect pore pressure using a convential dc exponent method. Analyzing tendency equation of dc exponent utilizing mathematical statistic’s method, the tendency lines has a similarly slop and different intercepts in same structural zone. The characters of tendency equation and dc exponent have been discussed and the concept of dc exponent has been further analyzed. It is believe that analyzed results will be help to detect pore pressure.
