在其商业服务的头三年中，连续速度测井迄今已在900多口威尔斯井中使用。所获得的数据表明，速度测井将对从钻孔获得的全部信息作出有价值的贡献。钻孔中的速度测量值是从脉冲声波通过侧壁的传播时间在短间隔上获得的。该测量值是所记录地层的弹性系数的函数，并且主要受压实度和地质年龄的影响。速度测井提供了一个以前在钻孔中没有测量过的附加参数。地质学家发现这种测井在对比、地层和岩性识别以及孔隙度和流体含量研究方面很有价值。经过适当校准的连续速度测井提供的速度信息比仅由井中检波器数据提供的速度信息更准确和详细，并正在迅速取代常规的井中速度测量。其他地球物理应用包括地震反射识别、实际反射深度的确定以及合成地震反射的实验室研究。Magnolia对开发速度测井仪器的勘探行业的贡献，以及随后的商业发布，使这种材料的展示成为可能。作者对Magnolia石油公司、Sinclair石油天然气公司、Warren石油公司、Ginther、Warren和Ginther以及Seismograph服务公司允许使用所提供的一些速度记录表示感谢。
In its first three years of commercial service, continuous velocity logging has been used in more than 900 wells to date. The data obtained indicate that the velocity log will make valuable contributions to the total information obtainable from a drilled hole. The velocity measurements in the borehole are obtained over short intervals from the travel time of pulsed sound waves through the sidewall. This measurement is a function of the elastic coefficients of the formations logged and is affected principally by degree of compaction and geologic age. The velocity log provides an additional parameter not previously measured in boreholes. Geologists are finding the log valuable for correlation, stratigraphic and lithologic identification, and porosity and fluid content studies. Continuous velocity logs, properly calibrated, provide more accurate and detailed velocity information than is provided by well geophone data alone, and are rapidly replacing the conventional well velocity survey. Other geophysical applications include seismic reflection identification, the determination of the actual reflection depths, and laboratory studies of synthetic seismic reflections. Magnolia's contribution to the exploration industry of the development of the velocity logging instrument, and then its release commercially, have made presentation of this material possible. The writers express appreciation to Magnolia Petroleum Company, Sinclair Oil and Gas Company, Warren Petroleum Corporation, Ginther, Warren, and Ginther, and Seismograph Service Corporation for permission to use some of the velocity logs presented.
