摘要/Abstract

摘要： 以胜利油田垦71地区的实际资料为例,用贝叶斯-序贯高斯模拟方法综合井间地震数据、测井数据和三维地震数据,建立了一个高分辨率三维波阻抗模型。该模型具有以下特点:1垂向分辨率明显高于输入的三维地震波阻抗;2横向上的变化趋势与输入三维地震数据的变化趋势一致;3增加了井间地震的约束,结果更加合理;4其准确性与三维波阻抗反演结果的准确性密切相关。

关键词: 三维模型, 贝叶斯-序贯高斯模拟方法, 垂向分辨率, 井间地震数据, 三维地震数据

Abstract: Three-dimension (3D) models were created by integration of geological data,well logs and seismic data for a better heterogeneity characterization.Well logs, cross-well seismic data and 3D seismic data in Ken 71 area of Shengli Oilfield were incorporated into a 3D model with sequential Gaussian-Bayesian simulation.The model generated with this technique has several advantages of higher vertical resolution compared with the 3D inverted acoustic impedance (AI),consistency of lateral variation as 3D inverted AI and more reliability due to integration cross-well seismic data.It is observed that the precision of the model depends on the 3D inversion.

Key words: three-dimension model, sequential Gaussian-Bayesian simulation, vertical resolution, cross-well seismic data, three-dimension seismic data
