Experimental Research Of Electrical Heating Buried Oil And Gas Pipelines

Electric heating oil transportation was developed as a kind of new transportation progress according to low temperature oil transportation of the single pipeline and circle oil transportation, after oil craft of activated water transportation of double pipelines.With wire across the steel pipe without gaps heating, heat will be conducted from surface insulator to the steel pipe, and made the transportation pipeline's linearity heating, it is a guarantee for liquid to heating identical and stabile. The experiment shows that the electric heating oil transportation can not only insurance for normal production of crude oil, reducing the mixed water a great deal, lowering the mixed water heat load of the furnace in station but also shorten diameter of the oil transportation, lowering the friction resistance, reducing heat waste. Moreover, substitute electric heating oil transportation for oil craft of activated water transportation of double pipelines, which can be benefit for economic nature gas greatly.Owing to the unstable environmental effect, electric heating power of buried pipelines change a lot in different seasons, without the theory calculation suitable for the fact, most electric heating power is bigger than need, on the one hand it increases the original invest and made the equipment sparing and wasting, and blind the manage in function on the other, made the manage even harder. In order to decrease the original invest for equipment and manage scientifically for oil transportation of the single pipeline, improve the convenience for rebuild of electric heating oil transportation in oil field and for the easily designing, the simulation for the temperature field and power experiment of electric heating oil transportation in oil field is urgently and necessarily. With the investigation of buried oil and gas transportation pipeline of electricity heating, this paper provide reference experimentation data for oil and gas transportation pipeline of electricity heating power, correct theory calculate formulae of electric heating power currently, makeup electricity heating technique in oil field at present, perfect collection technology in oil field. The study do benefit for energy conservation and economy in oilfield, make for persistence development in oilfield.The content of this paper: following the heat transfer theory and experimentation technology, we confirmed the studying extension about buried pipeline of oil and gas transportation electricity heating. By the examination investigation of inside room and locale examination, correct formula and experimentation data have been improved for locale electricity heating power. The technique of buried oil and gas transportation pipeline of electricity heating has been we improved by the examination investigation.
