Application of heavy oil cleaning agent in east South China Sea oil field
After the recovery of oil well production pipe string in Liuhua 11-1 oilfield,a large amount of oil is attached to the surface,which is difficult to clean.Through the analysis of oil pollution components,a kind of oil pollution cleaning agent is developed,which can reduce the viscosity of crude oil and improve the flow of oil pollution.By using the heavy-duty oil cleaning agent to clean the oil attached to the inner and outer walls of the pipe column,the cleanliness of the pipe column is increased by more than 90%compared with that without using the cleaning agent,which improves the field operation efficiency and reduces the environmental protection risk.
