【摘要】 针对当声波测井曲线不能很好地区分岩性从而造成传统的反演方法存在储层预测精度较低的问题,通过储层特征曲线重构的方法,重构出能够准确反映地层物性变化的拟声波测井曲线,用拟声波代替声波测井曲线进行地震反演。利用声波测井曲线重构技术对SN21井区进行了反演,反演结果较好地反映了储层的展布特征,有效地指导了生产工作。更多还原

【Abstract】 In allusion to the problems that lithology could not be identified by using acoustic curve and traditional methods of seismic inversion had low accuracy for predicting the reservoirs,by using the method of reservoir curve reconstruction,a pseudo-acoustic curve which could exactly reflect the physical property changes of reservoirs was reconstructed.Then pseudo-acoustics were used to replace acoustic logging curve for a seismic inversion.The pseudo-acoustic curve was used for seismic data inversion in Wellblock SN 21.The result of inversion shows that the method could effectively reflect the reservoir characters and guide hydrocarbon exploration in the area.更多还原
