摘　　要：渤海湾盆地QHD29-2区块东营组三段为一典型的构造-岩性复合圈闭,采用常规波阻抗反演和地震属性分析等技术难以有效预测储层及其含油气性。在岩石物理综合分析的基础上,以岩性和流体敏感弹性参数交会图版为指导,通过综合应用基于泊松阻抗(IPI)分析的储层预测方法以及以拉梅常数为主要参数的储层烃类检测方法,开展QHD29-2区块储层地震预测和烃类检测技术研究,探索出一套适合该区储层预测的地球物理技术流程。后经钻井证实该方法的预测结果准确、有效。The Ed3 of QHD29-2 block in Bohai Basin is a structure-lithology trap.The distribution of reservoir and hydrocarbon cannot be effectively predicted by conventional wave impedance inversion and seismic attribute analysis.On the basis of integrated analysis on petrophysical properties,guided by the crossplot of lithology and fluid sensitive elastic parameters,we combined reservoir prediction method based on Poisson impedance(IPI) analysis with hydrocarbon detection technique(Lame constant λ as main parameter) to carry out research on QHD29-2 block.As a result,a series of geophysical workflow suitable for the reservoir prediction in QHD29-2 block was proposed.The prediction result was proved by drilling.
