引言在共深度点技术出现之前,用于动校正的微小速度错误可以在单次复盖记录上很容易地察觉到,并且可以用某些适当的剩余速度校正来改正,或者在解释中是允许的,因为误差是明显的。既可定期作速度段得到速度剖面,也可用测井方法来验证速度函数。连续声波测井提供了获得连续速度讯息的一个便利的多的方法,但是其结果常需要用直接速度测量来校验。共深度点技术的出现,大大增加了对连续估算可靠速度的需要,因为合适的速度校 INTRODUCTION Prior to the common depth spot technique, small velocity errors for kinematic correction can be readily discerned on a single overlay record and can be corrected with some appropriate residual speed correction or, in the explanation, allowed Because the error is obvious. The velocity profile can be obtained periodically as a velocity segment, and the logging function can also be used to verify the velocity function. Continuous sonic logging provides a convenient and versatile method for obtaining continuous velocity information, but the results often require direct velocity measurements to verify. The emergence of a total depth point technique has greatly increased the need for a continuous estimation of a reliable speed because of the appropriate speed
