摘　　要：在地质综合研究的基础上,通过地震资料的分析与处理、测井曲线的标准化与特征曲线的重构、子波的提取与层位标定等一系列前期的处理,并优选反演参数,对歧北中斜坡沙三段开展GR拟声波测井约束反演,明确了有利砂体的展布及厚度,为该区的井位部署及储层评价提供了有力的支撑。There are complex relations between the oil and water of Es3 formation reservoir because of the sand body interactive overlays and lateral changes in Qibei slope. The existing seismic data has problems of the vertical and horizontal low resolution. Thus it can not meet the need of high precision reservoir predic- tion. Based on the synthetic study of geology, through the analysis and processing of seismic data, the standardization of well logging curves and reconstruction of characteristic curve, wavelet extraction and horizon calibration and some other early processing, and optimizing parameters, inversion study of GR simulation acoustic logging is carried about to define the exhibition and thickness of favorable sand body and to provide strong support for wells deploymented and reservoir evaluated in Qibei slope.
