我矿使用6—130—1型水龙头较多。这种水龙头的中心管与下部接头连接处的丝扣原为每时8扣的左旋细扣,锥度1:16。在钻进过程中,该处易被高压泥浆刺漏,影响泵压,污染人体和钻台,不利于安全生产。为了现场抢修,井队往往只好用电焊焊堵。这样,不但难能堵住,而且往往导致接头报废。此外,接头丝扣容易发生粘扣,检修中卸不掉接头时,只好用氧气割掉,接头就不能重复使用。同时,在用氧气切割时,中心管也被割掉一部
I mine 6-130-1-type faucet more. The faucet of the central tube and the lower connector at the junction of the original buckle was 8 buckle left thin buckle, taper 1:16. During drilling, the place is easily punctured by high-pressure mud, affecting pump pressure, polluting the human body and drilling platform, which is not conducive to safety in production. In order to repair the scene, the team often had to use electric welding plug. In this way, not only difficult to block, and often lead to scrapped connectors. In addition, the threaded joints are prone to tripping, overhauling unloading joints, had to cut off with oxygen, the joint can not be reused. At the same time, when cutting with oxygen, the center tube is also cut off
