随着中国海上油气勘探开发的深入,精确刻画构造势在必行,尤其是南海地区众多的小幅度构造。提出了从时间域和深度域运用闭合差校正和高精度速度分析,以及用高精度速度进行时深转换的办法对此问题作探索性的解决。在实际应用中,取得了良好的效果。
As China’s offshore oil and gas exploration and development in-depth, accurate characterization of the structure is imperative, especially in the South China Sea many small structures. A solution to this problem has been proposed by applying closed-offset correction and high-precision velocity analysis in the time and depth fields, as well as time-depth conversion with high-precision velocity. In practical application, it has achieved good results.
