岩石物理分析技术在储层预测中的应用
|
摘要
岩石物性分析是储层描述的基础工作,通过研究岩石的物性参数,建立岩石的体积模型.根据Gassmann理论,求取地层在含有不同流体时的密度、剪切模量、体积模量,通过分析测井曲线重构,完成测井曲线的环境校正,计算出测井的横波曲线.通过计算改善地震与测井之间1相关性,提高测井约束反演的质量和对油气的识别能力.
The analysis of the petrophysics is foundation for the reservoir depict,we get the rock parameters,and establish the structural model of the rock.We get density shear-module bulk module containing oil or gas at the deferent condition by Gaussmann theory.Calibrating the well curves by reconstruction,performing the well curves environmental calibration,calculating the shear wave of the well curves.Improve the correlation of seismic and well datum,perfect seismic inversion and enhance the ability of oil detection.
