Recently, this reporter came to the Dagang Oilfield Company Production Plant four oil extraction twenty-five board. I saw the top of the metering chamber separator 5 meters high, a female staff will be a wrist rough safety valve alignment interface, swiftly screw into the high-pressure section hoop, check the correct, slide down the ladder metering chamber, before and after 10 minutes. At this time of year, the sixteen units of the six production units must concentrate their efforts on loading, unloading and inspection of safety valves. This year, the station staff no longer have to worry about the loading and unloading of safety valves, because through technological innovation, they use a new type of safety valve. "In the past, the separator used was a high-pressure gas well safety valve with a caliber of 100 mm and a full weight of 60 kg, which was loaded and unloaded by four young men in 1 hour. The safety valve we are using now has only 1 kg Heavy. "A female worker said. It is understood that since the establishment of the "Four Small" team activities in Dagang Oilfield Company, the team, in combination with the actual production, set up an "innovation" small team and organized employees to tackle the weak links in management. The team leader told reporters that in the past team engaged in technological innovation, are technicians and production of the backbone of children, team members participate in the initiative is not high. Striving for "innovation" small group activities, everyone's enthusiasm was mobilized, love to think more employees. Technological innovation has become a bright spot in class competition. Activities, the maintenance class for board twenty-five station separator safety valve bulky, annual handling time-consuming and difficult to verify loading and unloading, the separator safety valve interface transformation as an innovative project to tackle. Metering separator is a high-pressure equipment, in order to ensure safety, they consult pressure vessel technical experts many times to understand the safety pressure range of oil-gas separator, master the working principle of safety valve and the use of norms. After repeated studies, the maintenance team cleverly changed the installation caliber, and succeeded in "grafting" the new safety valve to the separator on the basis of ensuring that the flow rate at the time of take-off succeeded, thereby greatly reducing the work intensity and achieving a single person easy loading and unloading Safety valve technical transformation of the original intention.
