Description
Technical field
The utility model relates in a kind of oil field oil recovery production process, and the crude oil in the oil well gathering line is heated and the crude oil Electric heating appliance developed.
Background technique
In the winter of north cold, in the oil field oil recovery production process, the ducted crude oil of oil well crude oil transmission is in lower temperature, its viscosity increased, mobile decline.Cause ducted oil gas to block, influence oil recovery amount.All adopt the physical heating mode to heat at present, comprising various Electric heating appliances.There is following point in the present Electric heating appliance that adopts:
1. adopt single heating chamber mode, the fluid heating is inhomogeneous.
2. adopt single warm single-control apparatus, energy consumption is relatively large, and using effect is undesirable.
3. the gas channel design is unreasonable, can not solve the vapour lock problem.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing crude oil Electric heating appliance, the utility model provide a kind of novel crude oil Electric heating appliance.This device uses two chambers mode of heating, adopts the double temperature double control setting, has designed special fluid passage, thereby has solved the vapour lock problem, has improved heats, has realized the dual control of heating process.
The technological scheme that its technical problem that solves the utility model adopts is: be provided with dividing plate one in tank interior, dividing plate cooperates with the heating cylindrical shell, makes it form two heated chambers.In the heating cylindrical shell some excellent core formula electric heating tubes are installed; Tank body is provided with pressure gauge, safety valve, two adjustable thermoswitch formula temperature controllers, connects base, crude oil inlet/outlet, sewage draining exit; Other is provided with an electric control box and is used to control heating system.
The heating cylindrical shell penetrates chamber, is connected and fixed with it by flange.Some excellent core formula electric heating tubes are made as two groups and penetrate in the cylindrical shell, wherein feel at ease a temperature sensing probe is housed, and monitoring heating pipe operating temperature to guarantee its safety, prolongs the working life of electric heating tube simultaneously.Heating tank intermediate clapboard top is provided with gas channel, and the middle and lower part is provided with oil flow channel, and the bottom is the profit passage, and part has realized the shunting in chamber of oil, gas, water; The import that is provided with chamber top, outlet be common to form unique fluid passage, guarantee crude oil by the time can fully heat.The sensing probe of two temperature controllers is installed in simultaneously on the conducting tube, and places near the outlet, guarantees the temperature of measured temperature for outlet crude oil fluid.
Two temperature controllers are respectively controlled one group of heating pipe, and the distribution of controlled heat pipe can be determined as required.Two temperature controllers are set on the different temperature values as required during use.Heating-up temperature rise to I temp controller (being set in lower limit) setting temperature the time, temp controller action, cut off I electric heating tube group; II electric heating tube group continues heating, and when heating-up temperature rose to the temperature that II temp controller (being set in CLV ceiling limit value) sets, II electric heating tube group also stopped heating.When the fluid temperature (F.T.) that flows in the chamber dropped to the temperature that the II temp controller sets, II electric heating tube group startup work continued heating.Temperature descends and when reaching the temperature that the I temp controller sets, temp controller is started working, I electric heating tube group startup work if occur.This moment, two groups of electric heating tubes heated simultaneously, and crude oil fluid temperature (F.T.) in the chamber is improved rapidly, and this heating process reciprocation cycle remains in the more stable scope fluid temperature (F.T.).
The beneficial effects of the utility model are: heating is rapid, temperature is even, efficient low-consume, can satisfy the requirement of oil well pipe network heating, can reach the purpose of economize on electricity as far as possible again.
