The Pubei Oilfield Gathering And Transportation System Optimization And Simplificationtechnology Research

At present.Daqing oilfield gathering tons of fuel gas to achieve an average30m3,and seven plant oil gathering ton of oily gas has more than50m3,significantly more than the average of Daqing oil field oil and gas gathering and transportation energy consumption,energy saving is the seven production plant to reduce the production costs.With the inefficient and will change the inefficient block continues to increase,the measurement of pumping unit well number decreases ceaselessly,oilfield ground system has exposed more and more problems.The low field ground system the main problems:one is the production of diminishing,so that part of the ground system load rate decreased year by year;two is inefficient wells has increased year by year,abandoned well,water injection well,bailing wells has increased year by year,invalid oil water route,with growth of water increased,heat loss is increased,leading to the production of operation energy consumption,the rising cost of unit operation.At the same time,the ground system equipment and pipelines in the long run,appear in succession the corrosion problem of aging.Therefore,to carry out oil gathering system optimization and simplification technology research is particularly important.The Pubei oilfield inefficient block well number less than 3port and to the unreasonable low measurement have many,for the maintenance of gathering system of normal production,separation from the system out of the oil well produced fluid by water to supplement the energy consumption for gathering and transportation system,resulting in rising.In order to maintain the sustainable development of oil fields,there is a need for oil gathering system technology research,set the control scheme and optimized,analysis,put forward the corresponding countermeasures,providing a scientific basis for decision making.The research on seven plant ground dendritic gathering system problems,study the properties of oil and oil gas water three phase flow in hydraulic,thermal calculation method,and gives the optimal modification scheme,thereby simplifying the design of labor intensity,save the design time,improve work efficiency,and ultimately achieve the purpose of energy saving.
