【摘要】 海安凹陷海北次凹的井大部分缺失声波测井,严重影响了测井约束反演的结果,不能有效地反映研究区的储层特征。在缺少声波测井的情况下,用Faust经验公式可以构建声波曲线。Faust公式适用于电阻率曲线与声波测井曲线之间具有良好统计关系的地层。对研究区的阜一段、泰州组地层用Faust公式构建了声波时差曲线,合成地震记录与井旁实际地震对应良好,反演的地层厚度误差相对较小。更多还原

【Abstract】 Most of wells in Haibei sub sag are lack of acoustic logging, which seriously influenced logging constrained inversion results, and can not effectively reflect the reservoir characteristics. In the absence of acoustic logging, with the Faust empirical formula, acoustic curve can be constructed . Faust formula is suitable for the strata with good statistical relationship between resistivity and acoustic logging curve. In the study area, acoustic logging curve in Fu I segment and Taizhou formation are formed with Faust formula, which shows that synthetic seismic record corresponds well with actual seismic and inversion of formation thickness error is relatively small.更多还原
