【摘要】 在低速层速度(地表直达波)已知的条件下,利用生产炮初至信息,用加权最小平方法和共轭梯度法建立的折射静校正数学模型,迭代求取长波长、短波长静校正量,在解决鄂尔多斯盆地北部的虚假小幅度构造问题及改善剖面质量方面取得了明显的效果。更多还原

【Abstract】 Given the velocity of low velocity layer (direct wave) and by means of the first break information of production shots and the static correcting mathematical model based on the weighted least squares and conjugate gradient method, we can calculate the static correction values of the long and the short wavelengths on the basis of iterative algorithm. This technique is obviously effective in solving the unreal minor structures in north Ordos basin.更多还原
