视地层水电阻率正态分布法在元坝气田探井解释中的应用

Application of normal distribution method of apparent formation water resistivity to the exploration well interpretation in Yuan gasfield

为了精细评价元坝气田储层特性,开展了视地层水电阻率正态分布方法研究。文章主要介绍了视地层水电阻率正态分布的理论基础,根据该气田不同储层的正态分布特征,总结出了利用该方法识别储层流体性质、开展厚层精细解释、评价储层非均质等方法,为储层精细评价提供了新的依据。

To evaluate detailed reservoir characteristics of Yuanba gasfield,we have carried out a method study on normaldistribution of apparent formation water resistivity.This article introduces mainly theoretical basis about normal distribution of apparent formation water resistivity.According to normal distribution characteristics of different reservoirs in the gas field,we use the method to do following aspects:to recognize fluid property of the reservoir,to divide thick layer for detailed interpretation,to evaluate reservoir heterogeneity,etc.These provide new evidence for reservoir detailed evaluation
