【摘要】 在砂泥岩薄互层条件下,以地震解释的层位为控制,以重构的声波测井曲线为基础,通过外推内插建立初始波阻抗模型,对初始模型不断更新,使得模型的合成记录最佳逼近实际地震记录。该方法将地震和测井信息有机结合,充分利用了地层的岩性特征信息,提高了对薄砂层的识别能力,在济阳坳陷临盘油田大芦家区块薄储集层预测中取得了较好的效果。图7表1参10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 Dalujia Block in the Linpan Oilfield,Jiyang Depression.更多还原
