China Petroleum & Chemical News Network reported recently that Puguang Gas Field implemented the self-innovated online plugging technology of immobility for the first time to solve the problems of running, emitting, dripping, and leaking of the purification device.
At the same time, it eliminates the possibility of hot fire and temporary electricity use during plugging.
There are risks of electric shock, explosion, fire, etc.
for the coming personnel
.
In the boundary area of the purification device, the leakage of condensate and heating steam is blocked, which is accompanied by the interference of medium temperature, pressure and leakage flow, which causes fluctuations in process parameters
.
This technology is suitable for on-line plugging of the non-moving fire of the condensed water and the heating steam of the device, to avoid the shutdown of the device due to leakage, to ensure the normal operation of the production, and to reduce the waste of energy
After nearly half a year, the team of R&D technicians has conducted three rounds of tests to repair the leaks, and continuously optimizes and summarizes the technology.
Since the promotion of immobility plugging technology, 33 locations have been successfully plugged, with a plugging success rate of more than 87%, effectively reducing the use of fire for plugging by more than 73%, and greatly reducing its speed, reliability, and small workload.
