在层速度计算中,倾角校正是不可避免的。文中列举了四种校正方法,通过对比分析和实算结果表明,用Δν—ν_φ量板法所得层速度与声测井计算的层速度最为接近。
In layer velocity calculation, tilt correction is inevitable. Four kinds of correction methods are listed in the paper. The results of comparison analysis and actual calculation show that the layer velocities calculated by Δν -ν_φ plate method are closest to those calculated by acoustic logging.
