滑轮系统是油井环空测试时,仪器起、下操作过程中重要的配套设备之一,现在油井环空测试常用的滑轮是吊滑轮和定滑轮两种,它们在实际使用过程中各有优缺点,都存在着许多无法解决的难题,而且都存在安全生产隐患。落后的滑轮系统已经不能满足目前的环空测试工艺要求,而且经常因此影响到正常的生产测试。难道就没有解决办法吗?有,那就是我们研制的便携式滑轮架。
Pulley system is one of the important ancillary equipment in the operation of the instrument during the annulus test of the well. Now the commonly used pulleys of the well annulus test are two kinds of suspension pulleys and fixed pulleys, each of which has its advantages and disadvantages in actual use , There are many unsolved problems, but there are also potential safety problems. Outdated pulley system can no longer meet the current requirements of the ring test process, and often therefore affect the normal production test. Is there no solution? Yes, that is, we developed a portable pulley carrier.
