【摘要】 在薄互层条件下,以地震解释的层位为控制,以重构的声波测井曲线为出发点,进行外推内插,形成初始波阻抗模型。通过对初始模型的不断更新,使得模型的合成记录最佳逼近实际地震记录。该方法突出了地层岩性特征信息,把地震和测井有机地联合起来,突破了传统意义上的地震资料分辨率的限制,提高了薄层的识别能力,在临盘油田大芦家地区的应用中取得较好的地质效果。更多还原

【Abstract】 Under the conditions of thin interbedding sandstone and mudstone,constrained by the interpreted seismic layers,taking acoustic curve-reconstruction as the base,extrapolating and interpolating in the interpreted seismic layers,an initial wave impedance model is generated.Keeping on modifying the initial model until the synthetic seismic traces approach the real seismic traces.The method could combine the seismic data with the logging data efficiently,making full use of the stratigraphic information,improving the seismic resolution.A good effect has been achieved in the thin reservoir prediction of the Da lu jia BlockIn the Linpan Oilfield,JiyangDepression.更多还原
