The Reach Of Cooling Doped In Qian’an Oilifeld

With the increase of water-bearing, Part of oil well water has more than crude oil phasetransition point. With the single well liquid producing capacity rising, wellhead oil outlettemperature, pipeline water-in-oil emulsion has been transformed into an oil-in-wateremulsion, emulsion viscosity is discreaseing, flow performance is improving, As the Coolingdoped and created a substantial condition.The Unheated gathering is no water, no drug, no passing the ball and It depends on thethe pipe wall of the physical and chemical properties to discrese the friction, the non-heatingtransportation of crude oil below the freezing point following.So the measure reduces projectinvestment, operating costs and the labor intensity of workers.The technology of Unheated gathering depends on the Production of single well liquidwater increasing, Oil consumption rising, Ground engineering rebuiltling, the crude oilproperty analysis and rheological analysis to make sure the moisture content of crude oil inthe phase transition point and wax precipitation point. By fitting the liquid production, watercontent, gas oil ratio and the length of the pipeline and other key parameters,we determine theboundary conditions of unheated gathering and transportation technology.By the chance ofgood pipe, pipeline buried depth,we realize the Cooling doped, system optimization, the oiland natural gas saving and at last energy saving and consumption reduction is achieved.The pilot test was carried out in QianAn oilfield in2008, and it isaccording to theexploration and experiment, we fund the boundary, condition key technology, and securitymeasures of the technology of Cooling doped.The technology of Unheated gathering wasPopularization and application on396oil wells in2011, it saves Gas400,000party,Electricity500,000degrees and it creats RM700,000.
