利用测井曲线研究江55区块沉积微相类型

Using logging curve study types of sedimentary micro-facies of Jiang 55 block

沉积微相是沉积体系中最基本的沉积单元,而其沉积特征可以用测井曲线来反映。通过研究自然电位和电阻率测井曲线形态与沉积特征的关系,本文描述了江55区块各种沉积微相的测井响应特征,最终识别出区块的主要沉积微相类型。

The Sedimentary micro--facies are the most basic sedimentary unit in the sedimentary sys- tem, and its sedimentary characteristics can be reflected by the logging curve. Through studying the natu- ral potential and resistivity logging curve shapes and sedimentary characteristics relationship, this paper describes various sedimentary mierofaeies characteristics of well logging responsed of the Jiang55 block, ul- timately identifys the main types of sedimentary facies of the blocks.
