| 摘 要： | 水基泥浆的声波时差测井资料因受泥浆侵蚀和井眼扩径的影响，不能真实反映地层信息。在声波严重失真的情况下，用Ｆａｕｓｔ公式可以对其校正。Ｆａｕｓｔ公式适用于电阻率曲线与声波曲线之间具有良好统计关系的地层。对研究区馆陶组地层用Ｆａｕｓｔ公式由电阻率曲线重构声波时差曲线，其合成地震记录与井旁实际地震道的相位和能量对比关系良好。

| Abstract: | Based on an analysis of Faust equation, we deduced the applicable condition of Faust equation. There is a good statistical relation between Rt and AC curves in Guantao Formation of the work area, which means that the applicable condition of Faust equation is met. The AC curves were rebuilt by Faust equation. The synthetic seismogram from the resulted AC has good agreement with traces in the vicinity of the well in terms of phase and energy. |
