俄罗斯应用散射地震波特征参数分析研究基岩结构及油气藏
|
摘要
应用地震方法勘探基岩油气藏是俄罗斯的强项之一。根据多篇俄文文献的介绍,概略归纳了应用地震波场散射分量识别基岩裂隙带及油气藏,应用散射地震波极化分析法研究非均质体结构,应用波速弥散与吸收异常指示油气藏等新技术新方法,从方法原理和应用实例等方面作了简介。实例表明它们在勘探基岩油气藏领域效果很好,值得参考借鉴。
Seismic survey is the most widely used and most effective method in exploration of hydrocarbon-bearing structures (or traps). Russia is leading in the exploration of basement oil & gas reservoir. Base on a review of several Russian literatures, the author introduced the methodologies of detection of basement fractured zone and reservoir with scattering of seismic waves, determination of the structure of heterogeneous bodies with polarization analysis, and inference of hydrocarbon reservoir with dispersion and absorption of wave velocity. Examples were also presented.
