随着高压喷射钻井技术的普及和发展,钻井要求的泵压也越来越高。目前我矿区多数井队泵压在150大气压左右,少数井队泵压达到200大气压。由于泵压高和其它种种原因,导致泥浆泵凡尔座冷缸刺坏,严重影响了高压喷射钻井工作的正常进行。为解决这一问题,矿区改革了沿用电焊和砂轮打磨的修复方法。旧方法费工,修复后一般只用上几小时或几十小时,最后还得换泵或拉回机厂修理。我们在五口井、五台泵试验了一种简单易行的现场粘
With the popularization and development of high-pressure jet drilling technology, the pumping pressure required for drilling is also getting higher and higher. At present, most of the drilling wells in our mining area are pumping at about 150 atm and the pressure of a few wells is up to 200 atm. Due to the high pump pressure and other various reasons, the slurry pump will cause damage to the Cooper cooling cylinders, seriously affecting the normal operation of the high-pressure jet drilling. In order to solve this problem, the mining area has reformed the repair method of welding and grinding wheel. The old method of fatigues, after repair generally only take a few hours or dozens of hours, and finally had to change the pump or pull back to the factory repair. In five wells, we tested a simple sticky on-site pump
