Application Research of Oil and Gas Transportation Under Normal Temperature in High Water-cut Oilfield

The oil-gas gathering and transportation system in Qinghai oilfield was optimized and improved by field experiments,then some problems in the existed oil-gas gathering and transportation system were solved,such as unsuitable technology,imbalance system capacity,equipment aging and pipeline corrosion.Some conditions including large loss of oil and gas,high energy consumption and low efficiency were also improved,which realized the object of energy saving and consumption reducing and provided a basis for future research.
