Abstract

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 (I_PI) 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.
