Description
Technical field
The utility model relates to a kind of thermal recovery oil well bio-fuel energy-saving heating apparatus in petroleum thermal recovery device field.
Background technology
In thickened oil recovery, adopt usually at present in oil well both at home and abroad and inject hot water or use electrical heating.The former has increased the loss of sewage load and energy, has increased cost of winning and environment pollution; Latter's power consumption is big, the cost of investment height.Along with the application of hollow rod, begin to utilize hollow rod that heavy oil wells is implemented the recirculated water thermal recovery recently.For example the applicant in first to file " pumpingh well circulating heater " (patent No. 200820226294.X) its main composition comprise carrier pipe in heater, high temperature delivery pump, well head delivery hose, return hose, crossover sub, oil pumper, polished rod eye, wellhead assembly, oil pipe, oil well pump, hollow rod, the well, carrier pipe is an insulating tube in the well, all coating or base section are exposed from top to bottom along carrier pipe outer wall in the well for this insulation layer, and wherein the interior carrier pipe of well is continuous tubular structure together with the insulation layer of its outer wall.The circulation of this mode more original injection hot water of heating or with electrical heating implement that the thermal recovery heating is effective, energy-saving and environmental protection, characteristics that input cost is low, and well solved carrier pipe insulation problem in the well.But the rational Application for heating furnace lacks the corresponding techniques support.
The utility model content
The purpose of this utility model is exactly the deficiency that exists at prior art, and a kind of aspect better thermal recovery oil well bio-fuel energy-saving heating apparatus such as thermal effect, energy-conservation, cost that add are provided.
Its technical scheme is: comprise the insulating tube in heating furnace, high temperature delivery pump, well head delivery hose, return hose, crossover sub, oil pumper, polished rod eye, wellhead assembly, oil pipe, oil well pump, hollow rod and the hollow rod, heating furnace adopts the hot water heating furnace of burning bio-fuel, in its fuel inlet place feeding screw is set, the top of feeding screw is provided with loading hopper, with loading hopper coupling be electronic strand cage and storage bin.
Such scheme also comprises: at the loading hopper inwall upper and lower stuff level switch is set, two place's switches are connected to electronic strand cage by controller.Between return hose and heating furnace, set up expansion tank.Carrier pipe is continuous tubular structure together with the insulation layer of its outer wall in the well.
The utility model is outside the technical characterstic and advantage that have kept " pumpingh well circulating heater " (patent No. 200820226294.X), owing to adopted the heating furnace of burning bio-fuel (as straw etc.), realize comprehensive utilization, conservation of power and the fuel oil of resource.Supporting electric charging device can be realized unattended automatic feed, thereby realizes that a set of equipment uses for many mouthfuls of wells, saves one-time investment and production run expense when guaranteeing the crude oil ordinary production.
Description of drawings
Accompanying drawing 1 is the agent structure schematic diagram of a kind of embodiment, and accompanying drawing 2 is amplification assumption diagrams of A part and the downward extension of hollow rod among Fig. 1.
The specific embodiment:
Embodiment 1, and in conjunction with the accompanying drawings 1 and 2, the horse head part of oil pumper main body 6 is connected with the adapter 5 of hollow rod 11 upper ends by polished rod eye 7 downwards.Seal in the hollow rod 11 after carrier pipe (steel pipe) 12 adds insulation layer 13 (bottom exposed part 14 is beneficial to heat conduction) in the well, hollow rod 11 is passed down through wellhead assembly 8 to down-hole oil tube 9 together with carrier pipe in the well 12, through oil well pump 10.The well head above ground portion is provided with bio-fuel heating furnace 1, high temperature delivery pump 2, well head delivery hose 3, return hose 4, and well head delivery hose 3 and return hose 4 are connected with hollow rod 11 by carrier pipe 12 in adapter 5 and the well goes into water circulation system.Carrier pipe 12 is continuously a pipe in used herein, and the centre does not have joint.Fuel inlet place at heating furnace 1 is provided with feeding screw 22, and the top of feeding screw 22 is provided with loading hopper 17, with loading hopper 17 coupling be electronic strand cage 19 and storage bin 20.
Embodiment 2, on the basis of embodiment 1, at loading hopper 17 inwalls stuff level switch 18 are set and are connected to electronic strand cage 19 with following stuff level switch 16, two place's switches by controller.Between return hose 4 and heating furnace 1, set up expansion tank 15.Combustion furnace 1 together with the part servicing unit by device in operation room 21.
Operating principle is a G.I.H carrier pipe 12 in hollow rod 11, hollow rod 11 hangs on the polished rod eye 7 of oil pumper 6, changing-over 5 is switched through in hollow rod 11 upper ends, return hose 4 links to each other with crossover sub 5, well head delivery hose 3 is communicated with carrier pipe 12 in the well, hollow rod 11 communicates with return hose 4, forms the input return flow line.
When viscous crude in the oil well need heat, after starting heating furnace 1, the stove medium was heated to uniform temperature, and circulation pump starts, and heat medium through ground delivery hose and carrier pipe, is transported to the shaft bottom, gave heating crude oil.The medium of finishing interchange of heat returns heating furnace through hollow stem, ground return hose, expansion tank.When the fuel in the feed hopper reached stuff level switch, the electronic strand cage of the material loading in the storage bin started, and gave the feed hopper material loading automatically.When the material loading amount reached stuff level switch, the electronic strand cage of material loading stopped material loading.
