摘要
选取中原油田的大量岩心,采用常规岩石力学测试方法测定了岩石的可钻性、声波测试方法测定了岩石和岩屑声波时差,通过对测得的岩石可钻性级值和声波时差进行回归拟合,得出了中原油田岩石可钻性与声波时差的关系式。现场应用表明,该关系式较好地反映了中原油田地层岩石可钻性与声波时差的关系,可以在优选钻头时作为参考或直接应用。
A wide range of core samples from the Zhongyuan Oilfield have been tested with drillabilities and acoustic travel time using conventional lab methods. The relationship between drillability of rocks from the Zhongyuan Oilfield and acoustic travel time have been developed based on regression of drillability rating to acoustic travel time. Field applications show that the relationship depicts the relation between rock drillability and acoustic travel time in the Zhongyuan Oilfield, and this formula can be referred or employed directly when bit selection.
