The drilling team is mainly engaged in drilling. Workers have a division of labor, including drillers and ordinary workers, diesel engine or generator drivers, mud workers and so on. The drillers have strong skills and need training before they can take up their posts. Some of them have low technical content and can master skills quickly, but they also need training. Now the labor intensity is much better than in the past, and there are priorities. For example, in the process of drilling, ordinary work is very easy, especially when drilling deep wells. It takes a long time to change a drill pipe, so ordinary workers are idle and only the driller is operating. Better than the homework team. The operation team was dirty when working, and the crude oil spilled all over the floor, which was difficult to clean up and the labor intensity was not small. Compared with the two, the driller is better.
