摘要
ＡＰＩ钻县数字螺纹接头具有使用寿命长等特点，因此在国外已经全面推广应用。但是由于种种原因，有一少部分ＡＰＩ钻具数字螺纹接头在我国还没有推广应用，因而发生了多起非正常的钻具失效事故。通过对我国钻具螺纹接头使用情况进行全面调查研究，对各种钻具螺纹接头的结构形式进行对比分析，对我国钻铤螺纹接头和ＡＰＩ规定的钻铤螺纹接头弯曲强度比进行计算，指出了我国在推广应用数字螺纹接头方面存在的问题和产生的后果，找出了某些数字螺纹接头未能在我国推广应用的具体原因。建议国家有关部门牵头组织螺纹量规生产厂、钻具生产厂和油田，系统解决数字接头在我国全面推广应用的问题。
API drilling digital nipple has the feature of long life, so it is widely used in foreign countries. But for different reasons, a small portion of API drilling digital nipple has not been widely used in China, and some times there are failure accidents of the drilling equipment when used improperly. Based on the survey for the drilling nipple in China and the comparativae analysis for the structure of the different drilling nipple, on the computation for the drilling nipple strength prescribed by API, the author points out the problems and re sults when the digital nipple is used in China. Also the author points out the exact reason why certain digital nipple is not widely used in China. The author suggests that with the help of the government, combined with the screw thread gauge manufacturer and oil field to solve the problems of digital nipple use in China.
