【摘要】 对于复杂波场储层研究,非线性反演在解空间的性质、状态方面比线性反演更具有优势。基于非线性最优化理论,本文提出了构造—测井约束下的地震资料非线性反演方法,该方法综合了测井约束反演和宽带约束反演等线性反演方法的优点。实际地震资料的处理结果表明,该方法运算速度快、稳定、精度高,在油气储层研究中具有良好的应用前景。更多还原

【Abstract】 Non-linear inversion has more advantages over linear inversion in aspects of solution space’s property and state for studying the reservoir with complex wave. Based on non-linear optimal theory,the paper presented a method for non-linear inversion of seismic data under structural-logging constrain, which integrated advantages of such linear inversions as logging-constrained inversion and broadband-constrained inversion. The processing results of real seismic data showed that the method has advantages of fast computation, stable and high precision, which has good applied prospect in oil-gas reservoir studying.更多还原
