【摘要】 通过关联维、李指数、突变指数三种非线性参数和常规地震波场参数(以均方根振幅RMS为例)对地质模型中砂体组合变化的响应分析,并结合非线性参数值与实钻井砂体组合变化的研究表明,非线性参数对砂体组合的变化具有更好的分辨能力。应用该技术在于奇地区白垩系进行非构造圈闭发育区预测,共落实非构造圈闭线索10个。更多还原

【Abstract】 Through the three kinds of nonlinear parameters which are association correlation dimension,Lyapunov exponents and parameter of catastrophe,and conventional seismic wave parameters taking RMSroot mean square as an example,response analysis of sand composition change in the geological model is studied.Combining the nonlinear parameter value and sand composition changes of real drilling,this research shows that nonlinear parameters have a better resolution for the change of sand composition.This technology is applied to the cretaceous in Yuqi area to predict non-structural trap development zone,a total of 10non-structural trap cues are found.更多还原
