基于斑块饱和模型井控属性融合法油气检测
The well-controlled attributes fusion method for hydrocarbon detection based on patchy-saturation model
摘要
Abstract
At the present stage,the recognition of reservoir fluid mainly relies on seismic amplitude anomalies and elastic parameters difference.In practical applications,there are always problems that seismic amplitude response is not obvious to hydrocarbon and the elastic parameters distinction between hydrocarbon and water is not clear.So conventional methods would lead to multiplicity of hydrocarbon detection.The oil-bearing reservoir leads to more strong velocity dispersion and energy attenuation of seismic wave than water-bearing reservoir,so it is feasible to use patchy-saturation model to sort hydrocarbon-sensitive frequency.In this paper,we obtain hydrocarbon-sensitive factor by merging velocity dispersion strong and energy attenuation strong,use the information of drilled reservoir in wells to control the merge answers and proposed the well-controlled velocity dispersion and energy attenuation attributes fusion method for hydrocarbon detection.The practical data test from Bohai A oilfield proved that this method can effectively predict hydrocarbon reservoir.关键词
