Description
Technical field: the utility model relates to a kind of nitrogen heater for oil well particularly heavy oil wells, the nitrogen operation of high-solidifiability oil well note.
Background technology:
The operation of oil well note nitrogen is one of technological measure improving oil well output, more and more extensive in the application of Oil Field in recent years.In order to improve the effect of increasing production of oil well nitrogen injection operation further, produced on-site practice shows to be necessary to provide heat energy in stratum, in order to reduce viscosity of crude, strengthens crude oil flow ability, remove oil reservoir and pit shaft blocking, thus reach the object improving nitrogen injection effect and incremental oil production.But, the process unit that on-the-spot current still shortage can satisfactoryly solve the problem.
Utility model content:
The purpose of this utility model be to provide a kind of rational in infrastructure, the efficiency of heating surface is high, the oil well of long service life note nitrogen heater.
The technical solution of the utility model is as follows.This kind of oil well note nitrogen heater is made up of housing, electric heating element, nitrogen coil pipe, content gauge, temperature measurement unit, nitrogen inlet and outlet, tank filler sleeve and outlet valve, its structure assembled relation is as follows: be provided with nitrogen coil pipe in housing, bottom is provided with electric heating element, housing one side roof part is provided with nitrogen inlet and outlet, nitrogen inlet is connected into and out of end with nitrogen coil pipe respectively with outlet, housing opposite side top is provided with the content gauge and temperature measurement unit that are connected with housing cavity, is provided with tank filler sleeve and outlet valve in the middle part of housing end face.During use, this device is placed near well mouth of oil well, and nitrogen inlet is connected with well mouth of oil well pipeline with nitrogen making and injection apparatus for work respectively with outlet.During work, first in this device case, be filled with conduction oil by tank filler sleeve, be filled with oil mass and control at proper height by content gauge adjustment; Then nitrogen is inputted from nitrogen inlet, circulate through nitrogen coil pipe; By electric heating element by the heat-conducting oil heating in housing to high temperature; Nitrogen after heating is defeated by oil well by the nitrogen outlet on housing and is noted nitrogen process pipelines under Injection Well; In the course of work, the hot air in housing is discharged by outlet valve.
The utility model reasonable in design, area of dissipation is large, and the efficiency of heating surface is high, long service life, utilize it can complete the operation of oil well heat injection nitrogen preferably, reach the object of oil well viscosity reduction, de-plugging, volume increase, be particularly suitable for heavy oil wells, high-solidifiability oil well improves exploitation production effect.This heater is not pressure vessel, can bear the nitrogen pressure of 0Mpa ~ 45Mpa, and nitrogen discharge capacity can reach 100 cubes ms/min, can realize heating without ladder between 0 DEG C ~ 400 DEG C.This device also can be used for other gas-heated.
