Abstract
The utility model relates to a circulating heating system for a pumping well, which belongs to the field of oil production industry. The technical scheme of the utility model is as follows: the circulating heating system consists of a heater, a high temperature delivery pump, a wellhead delivery hose, a return hose, an adapter, a pumping unit, a polished rod eye, a wellhead device, an oil pipe, an oil well pump, a hollow sucker rod and a borehole delivery pipe, and the outer wall of the borehole delivery pipe is provided with a heat-preserving layer, which is wrapped on the whole outer wall of the borehole delivery pipe or the outer wall except the bottom part of the outer wall from the top down. A heat-preserving composite metal pipe is adopted as the borehole delivery pipe in order to effectively deliver heat down to the bottom of the well. The main body of the borehole delivery pipe is a continuous steel pipe (better matched with the continuous hollow sucker rod), and is characterized by high temperature resistance, longer service life and high pressure resistance. The utility model is better in terms of heating effect, energy saving, cost and the like.
Description
Technical field
The utility model relates to a kind of pumpingh well circulating heater in oil exploitation extracting device of oil 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.Nearest application along with hollow rod, begin to utilize hollow rod that heavy oil wells is implemented the recirculated water thermal recovery, its main composition comprises carrier pipe in the 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, well, the circulation more original injection hot water of heating of this mode or with electrical heating implement that the thermal recovery heating is effective, energy-saving and environmental protection, characteristics that input cost is low.But, cause rate of energy to reduce the corresponding raising of cost because the down-hole degree of depth long (common thousands of rice) if carrier pipe is not taked certain insulation measure in the well, certainly will occur heat part in the process of carrying downwards and run off.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of better pumpingh well circulating heaters in aspect such as thermal effect, energy-conservation, cost that add are provided.
Its technical scheme is: 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, the outer wall of carrier pipe is provided with insulation layer in well, and all coating or base section are exposed from top to bottom along carrier pipe outer wall in the well for this insulation layer.
Carrier pipe is continuous tubular structure together with the insulation layer of its outer wall in the well.
Effect of the present utility model:
1, carrier pipe adopts clad pipe in the utility model well, and promptly the upper outer layer at steel pipe has added insulation layer, effectively delivers to the shaft bottom to guarantee heat.Heat insulation layer is not established in the lower end of carrier pipe in the well, looses to the shaft bottom fast to guarantee heat
2, the carrier pipe main body is continuous steel pipe (more mating with continuous hollow rod) in the utility model well, has the heatproof height, and prolong application life, withstand voltage high characteristics.
3, heater can be selected combustion gas or electrical heating for use according to the oil well actual state, the optional water of medium or add deep fat.Can use for many mouthfuls of wells by a set of equipment simultaneously, save one-time investment and production run expense in the time of with assurance 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 partial enlarged drawings of the interior upper and lower end of carrier pipe of well among Fig. 1.
The specific embodiment:
Embodiment is with reference to attached Fig. 1 and 2, and the horse head of oil pumper main body 6 part 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 heater 1, high temperature delivery pump 2, well head delivery hose 3, return hose 4 passes through adapter 5 and the interior carrier pipe 12 of well is connected the stroke water circulation system with hollow rod 11.Carrier pipe 12 and hollow rod 11 are continuous pipe in used herein, and the centre does not have joint.
Embodiment 2, on the basis of embodiment 1, all coat insulation layers 13 (bottom does not have exposed part 14) in the well outside the carrier pipe (steel pipe) 12, can suitably reserve the gap of interior carrier pipe 12 of well and hollow rod 11 like this, are beneficial to heat conduction.
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, heat to medium by heater 1, and arrive the shaft bottom, and, finish interchange of heat by hollow rod 11, return hose 4 formation return flow lines by carrier pipe 12 pumped (conveying) mediums in high temperature delivery pump 2, well head delivery hose 3 and the well.
Claims (2)
1, a kind of pumpingh well circulating heater, 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, it is characterized in that: the outer wall of carrier pipe is provided with insulation layer in well, and all coating or base section are exposed from top to bottom along carrier pipe outer wall in the well for this insulation layer.
2, pumpingh well circulating heater according to claim 1 is characterized in that: carrier pipe is continuous tubular structure together with the insulation layer of its outer wall in the well.
