China Petrochemical News reported that the air in southern Xinjiang in April was fresh.
The Bashto Oil Gathering Station, more than 700 kilometers away from the factory, is Sinopec's oil production team stationed in the westernmost part of my country.
It is reported that the polished rod sealing device for mechanical pumping wells is generally composed of four to five layers of packing.
The above two methods are time-consuming and labor-intensive.
To this end, the technicians of the station independently designed a combined tool for dismantling and assembling the packing by studying the structure of the packing box and the packing incision.
According to calculations based on the average packing replacement of each well every 20 days in the past, there are currently 7 pumping wells in the block that replace the packing 127 times a year, saving 0.
