Abstract
The utility model relates to an automatically controlled some firearm in pit comprises distribution storehouse, temperature tube, distribution sheath, heating rod, righting fin piece, heating pillar, tail string. The upper end and the lower end of the heating protective tube are respectively connected with a wiring sheath and a tail hanger through threads, a wiring bin is arranged in the wiring sheath, a temperature measuring tube and a heating rod are arranged in the wiring sheath and the heating protective tube, and a righting fin is arranged between the testing tube and the heating rod. The utility model discloses simple structure, reasonable in design reliable operation, the heating efficiency is high, can satisfy the needs that oil well fire flooding exploitation technology and production were actual, is favorable to the popularization and application of fire flooding oil recovery technology.
Description
Technical field:
The utility model relates to a kind of down-hole specific purpose tool that is used for oil well fireflood production practice.
Background technology:
Along with oil field development enters the later stage, oil well output reduces, and the exploitation difficulty is increasing.In order to improve crude output and recovery ratio, it then is the key equipment of implementing this kind production practice that part oil district has adopted oil well fireflood production practice, down-hole igniter.At present, the on-the-spot various ignition device ubiquity effect of using is low, and technical problems such as poor reliability have seriously restricted the development and the application of fire flood technology.
The utility model content:
This novel purpose be to provide a kind of designs simplification, heating function height, reliable operation down-hole electronic control ignition device,
This is novel be achieved in that this kind down-hole electricity firearm by cable distribution compartment, temperature tube, distribution sheath, heating pole, set upright fin, heating pillar, tail and hang and form.Heating pillar upper and lower side is hung with tail with the distribution sheath with screw thread respectively and is connected, and is provided with cable distribution compartment in the distribution sheath, is provided with temperature tube and heating pole in distribution sheath, the heating pillar, is provided with between testing tube and the heating pole and sets upright fin.When implementing the igniting operation, this firearm is connected in the lower going-into-well of oil pipe bottom, firing cable takes to be bundled in the mode that oil-pipe external wall is lowered to, realize joining by the down-hole connector with igniting resistance, air injects oil reservoir by oil pipe, ground control system is in more than the oil reservoir burning-point injection oil reservoir air themperature by point of adjustment firearm power, reaches the purpose of lighting oil reservoir.Use proof through the scene, this igniter can be with 500Nm
3The gas of/d is heated to 450 ℃, and continuous firing.
This new structure is simple, and is reasonable in design, reliable operation, and the heating function height can satisfy oil well fireflood production practice and produce actual needs, helps applying of fire flood technology.
Description of drawings
Fig. 1 is this novel structural representation, and Fig. 2 is an electronic control ignition device working state schematic representation.
The specific embodiment:
As shown in Figure 1, this novel by cable distribution compartment 1, temperature tube 2, distribution sheath 3, heating pole 4, set upright fin 5, heating pillar 6, tail are hung 7 and are formed.Wherein, cable distribution compartment 1 top is connected with electric heater with tubing hanger, and power cable, cable for measuring temperature all at this distribution, enter heater.Temperature tube 2 inserts cable for measuring temperature, in order to heating pole 4 head and the tail parts are carried out thermometric.Distribution sheath 3 is the wiring storehouse of power electricity, and insulation, seal cavity are arranged in it.Totally 6 of heating poles 4 are arranged in the heating pillar 6, in order to heated air.Set upright 5 pairs of 6 heating poles of fin and 1 temperature tube and play fixedly centralizing function, also increase the area of dissipation of heating pole simultaneously, improve the efficiency of heating surface of gas.Heating pillar 6 is the protection tube of heating pole 4, also is the passage of heated air.Tail is hung 7 bottoms can connect tail pipe.But 1000 ℃ of this heater heatproofs, insulation voltage 1800V (three-phase).
Among Fig. 2, instrument cabinet 8, switch board 9, oil well casing 10, oil well oil conduit 11, strain relief clamp 12, cable 13, down-hole connector 14, igniter 15, temperature transducer 16.
