Center station video monitoring and manual inspection judgement, third is that carrying out comprehensive descision by analysis system operating parameter.Once it notes abnormalities,
Outlet electric valve is closed in horse back termination of pumping, reduces leakage rate.
Embodiment:
Certain oil field has 123 website liquid measures less than 120 sides at present, and 49 website (23%) day processing liquid measures are less than 60m3, stand
Point operational efficiency is low, management difficulty is big, security risk is high；Second is that with the lasting development of oil field low cost strategy, oil-water well number
It is continuously increased, and under the current conditions that the comprehensive recruitment of individual well persistently reduces, it is necessary to from optimization, simplify ground process flow, is pacifying
The unattended construction of Efforts To Develop on the basis of loopful guarantor is controlled, is finally reached the purpose of personnel reduction and enlargement.
Traditional booster station one-time investment 2,000,000 or so, occupied area 2000m2.Utilize the sledge charge of oil gas of the utility model
Defeated device is mixed to be transformed former website, every set mix defeated plant investment be 1,800,000 or so, due to do not have surge tank, heating furnace with
And the facilities such as duty room, occupied area will save 70% or more.Conventional station operating cost mainly includes associated gas burning, oil transportation
Pump electric energy consumption and cost of labor.It is mainly electric heating energy consumption and oil transfer pump electric energy consumption that sledge charge of oil gas, which mixes defeated operating cost, is offset
After falling oil transfer pump energy consumption:
Conventional station operating cost: associated gas consumption 285 sides/day × 0.35 yuan/side=100 yuan/day；Cost of labor disappears more
(100000 yuan/year × 2 people are normally five people according to website staffing to consumption, and at most only need three using the oil transportation sledge
People)/365 days=548 yuan/day.Total 648 yuan/day.
Sledge charge of oil gas mixes defeated operating cost: 60 kilowatt hour × 0.6 × 0.62 yuan of electric heating energy consumption/degree × 24 hour=536
Member/day spends more 436 yuan/day of expense compared to combustion gas, reduces two people of recruitment if comprehensively considered, can save 112 yuan daily.
A small amount of power consumption is although increased compared to traditional booster station, but generally investment is reduced, operating cost is reduced, accounted for
Ground area is reduced, station facilities and personnel are greatly decreased, and maximum advantage is that security risk is greatly reduced, and can be realized really
Website in meaning is unattended.
