Description
Technical field:
The utility model relates to a kind of foam rods water pumping gas production automatic charging device, is used for the field that the oil gas field foam drainage gas recovery is produced, and can automatically throw at regular time and quantity foam rods and foam ball toward the down-hole.
Background technology:
Along with gas field development enters the middle and later periods, the high moisture problem that is difficult to avoid that becomes.Gas reservoir pressure and natural gas flow speed progressively reduce, and formation water or condensed liquid can't be carried out pit shaft with air-flow, thereby cause the shaft bottom hydrops, have a strong impact on gas well production.Foam drainage gas recovery technique is the more method that can effectively get rid of the shaft bottom hydrops of present the field.
At present, adopt to pit shaft of foam drainage gas recovery technique injected blowing agent more both at home and abroad, or drops into foaming rod, foamed ball by oil pipe, with shaft bottom hydrops foamed, utilizes the flow at high speed of natural gas to take the hydrops of foamed out of shaft bottom.Yet the existing complex process of injecting blowing agent is thrown in the foaming rod or foamed ball need to drive a well, closing well is thrown in operation, will bleed off the part natural gas when driving a well, and causes waste, the gas well less to gas production, and financial cost is relatively high; And loaded down with trivial details operation causes and is difficult to realize automation.Therefore, solving blowing agent input problem tool is of great significance.
Summary of the invention:
The purpose of this utility model is: design a kind of automation control, timing caber ball-throwing apparatus, be used for reducing the cost of water pumping gas production, the labour intensity that alleviates the employee, raising safety, reduction air pollution.
The technical solution of the utility model is: the caber ball-throwing apparatus that is used for foam drainage gas recovery mainly comprises: explosion protection D. C. electric machine, photoelectricity are near limit switch, driving gear pair, central axis, wheel disc, charging gate valve, charging aperture, pressure pan, ellipse head, cartridge, wellhead flange etc.The explosion protection D. C. electric machine is arranged on the top of pressure pan, and clutch end connects driving gear pair, and transmission of power is arrived central axis; Central axis vertically passes from the pressure pan top center, and opening portion seals with high-pressure sealing stuffing, and the lower end of axle is arranged in sliding bearing, and sliding bearing is arranged on the gripper shoe of bottom; Central axis and wheel disc welding, wheel disc is two circular slabs in up and down, surrounding is processed with uniform circular hole; Cartridge passes this circular hole and wheel disc welding, is evenly distributed on a circumference, and one of them remains with well head and just in time aligns; The rotation of explosion protection D. C. electric machine is controlled near limit switch by photoelectricity, sets the time interval of rotating by time timer, and the angle that at every turn turns over is folded angle between two cartridges; Pressure pan is to be welded by two ellipsoidal heads of cylindrical thick-wall cylinder and up and down; Charging aperture and charging gate valve are equipped with in the upper end of pressure pan, and wellhead flange is equipped with in the lower end.
The beginning when filling with substance is closed head valve, opens the charging gate valve of top, feed in cartridge by gate valve, charging aperture, often install a barrel, manually control electric machine rotation and once (namely turn over two angles between barrel), then fill next barrel, until all barrels are filled.
During normal operation, close the top the charging gate valve, open head valve.Set the interval time of electric motor starting, and start " automatically " function.Motor driven gear, gear driven rotating shaft are rotated, rotating shaft and cartridge rotate together, and when angle that rotating shaft turns over equaled angle between adjacent two barrels, limit switch was controlled motor and stopped, this moment, one of them feeding tube just in time aligned with the position of well head, and foam rods is put in well.Timer begins timing simultaneously, and after certain hour (by the time interval of setting), motor starts again, drops into second charge bar.
The utility model beneficial effect is: compact overall structure, and high-pressure charging cylinder two ends employing ellipsoidal head, intensity is high; Adopt photoelectricity automatically to control near limit switch and PLC, can accurately control rotational angle and the time interval; Motor adopts the explosion-proof direct current generator of 24V, and safe and reliable, power supply can be provided by solar panels, energy conservation.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 sectional drawing that to be the utility model get along the upper cover lower surface.
In figure: 1. explosion protection D. C. electric machine, 2. photoelectricity is near limit switch, 3. driving gear pair, 4. central axis, 5. wheel disc, 6. charging gate valve, 7. charging aperture, 8. pressure pan, 9. wellhead flange, 10. cartridge, 11. ellipse heads.
The specific embodiment:
Describe structure of the present utility model and embodiment in detail below in conjunction with accompanying drawing.
The utility model foam rods water pumping gas production automatic charging device mainly is comprised of near limit switch 2, driving gear pair 3, central axis 4, wheel disc 5, charging gate valve 6, charging aperture 7, pressure pan 8, wellhead flange 9, cartridge 10, ellipse head 11 etc. explosion protection D. C. electric machine 1, photoelectricity.
Explosion protection D. C. electric machine 1 is arranged on the top of pressure pan 8, and clutch end connects driving gear pair 3, and transmission of power is arrived central axis 4; Central axis upper end rotating part seals with high-pressure sealing stuffing, and the lower end of axle is arranged in sliding bearing, and sliding bearing is arranged on the gripper shoe of bottom; Central axis and 5 welding of two of up and down wheel disc, and wheel disc and cartridge 10 welding, cartridge is distributed on a circumference, and one of them barrel and well head just in time align; Pressure pan is welded by two ellipsoidal heads 11 of cylindrical thick-wall cylinder and up and down, makes construction of pressure vessel more reasonable, and is lightweight, intensity is high; Charging aperture 7 and charging gate valve 6 are equipped with in the upper end of pressure pan, and wellhead flange 9 is equipped with in the lower end, and wellhead flange connects with wellhead sluice valve.
