海上多波多分量地震烃类检测方法研究

HYDROCARBON DETECTION METHOD OF OFFSHORE MULTI-WAVE AND MULTICOMPONENT SEISMIC DATA

以YGH盆地岩石为实验对象,介绍了多波地震属性参数比与地层含油气性的关系以及多波地震属性参数比的计算方法。提出了联合利用多波地震属性参数比(振幅比、速度比和泊松比)检测气层的方法。钻井实践证明该方法是可行的、有效的。

Taking the Yinggehai Basin for example, the correlations are introduced of mutiwave seismic parameter ratio to hydrocarbon bearing property. The way of getting muluwave seismic parameter ratio is given in the paper. The method that uses two or three muluwave seismic parameter ratios (amplitude ratio, velocity ratio and Poisson ratio) to detect hydrocarbon is given, loo. For the wells drilled, the method is proved to be probable and effective.
