根据目前国内在钻头选型方面存在的困难和问题，提出了利用测井资料进行钻头选型。通过室内试验和现场资料统计建立了地层岩石声波时差与岩石可钻性关系模型，结合巴楚地区情况进行钻头合理选型，得出了该区初步钻头选型结果，并在现场进行初步应用，取得了良好效果。
According to the current difficulties and problems in bit selection in our country, we propose the use of logging data to drill bit selection. Based on the laboratory test and field data statistics, the relationship model between rock acoustic time difference and rock drillability was established. Based on the situation of Bachu area, the reasonable bit selection was made. The preliminary bit selection results of the area were obtained and applied in the field. Achieved good results.
