What is the press of work?
Pressing the task is a term that refers to the repair of the oil well. Cement porridge, which is usually a mixture of cement, water and fine sand, is pumped into a housing or pipe that has been cracked or otherwise damaged. The porridge is connected by holes, effectively repair damage and allows you to continue using.
Another name for pressing the work is Bradenhead Squeeze; In order to be repaired, Bradenhead must be closed. If this is not the case, the cement comes from the top of the tube instead of the opening wiring. The process of repairing the cracked oil pipeline using the compression task includes a few steps, starting with the porridge pumping down into the pipeline. It is important to pump sufficiently to connect the holes, but not so much that it cannot be removed from the system before setting. Bradenhead is then closed.
After the initial preparations, the pumps are used to lead oil from Studnyzačalo. This causes the pipe content to draw on the surface thatIt now consists of a large amount of cement porridge. Because the pipeline is limited, the content cannot leave the tube.
pump pressure forces porridge out through any available openings that can only be damaged pipe areas at this point. As the pressure continues, sand and cement particles are stored in cracks, while water and oil are pushed, leading to the concept of "pressing". Finally, it repairs the pipe by creating a seal at any point that had a crack or hole.
As soon as the pressure in the pipeline rises, indicating that the holes have been connected, it is important to remove any excess cement before setting at the bottom of the pipe. This is done by stopping pumps and opening Bradenhead. The pumps are started again and all the water, oil and cement porridge from the pipe is pumped.
After the pipe is cleaned over excess cement, the patches can cure to cure to repairLoops squeezed permanent. The pipes can then be re -connected to a delivery pipe that takes oil from the well and delivers it to the storage area. The pumps are restarted and the work continues, usually after a minimum amount of downtime and expenditure.
