小鼠洞卡钳和方钻杆风动旋扣器相配合,是钻井过程中完成接单根的一种专用装置。 1978年初,我们开始研究小鼠洞卡 钳。对进口的渤海4号钻井船上的小鼠洞 接单根装置(简介见本刊1978年第2期33 页)进行了测绘、仿制以及现场试验,在 此基础上设计了D_1-200型小鼠洞卡钳。 1981年在中8-78井进行了试验,试验结果 表明该装置比仿制的更好用,自动化程度 更高,安全可靠,使用寿命长,很受井队 工人的欢迎。
Mouse hole calipers and square drill pneumatic rotary match, is the completion of drilling a single root of a special device. In early 1978, we started to study mouse hole calipers. D 1-200 mice were designed on the basis of surveying and mapping, imitation and field experiments on the single hole device for mouse in Bohai No.4 drilling ship (introduction, see the article in 1978, No. 2, 1978) Hole calipers. In 1981, a test was carried out in well 8-78. The test results show that the device is better than imitation, more highly automated, safe and reliable, and has a long service life. It is very popular with well crew workers.
