Abstract
The utility model discloses a crude oil single well pipeline load type automatic liquid medicine adding device which comprises a medicine containing tank. A piston is arranged in the medicine containing tank, fixedly connected with a connecting rod extending out of the medicine containing tank and driven by the connecting rod to move vertically in the medicine containing tank. The portion, extending out of the medicine containing tank, of the connecting rod is sleeved with a spring. The side wall of the medicine containing tank is respectively communicated with a medicine inlet pipe and a medicine outlet pipe. The medicine inlet pipe and the medicine outlet pipe are lower than the maximum stroke portion of the piston. According to the automatic liquid medicine adding device, liquid medicine is directly input in an oil pipeline through high pressure, so that the problem that medicine addition without a halt can not be achieved through an existing medicine adding method is solved, meanwhile, the medicine adding device is automatically operated in the medicine adding process, manual medicine addition is not needed, under the condition that normal production work of an oil field is not affected, labor is saved, and production efficiency is improved.
Description
Technical field
The utility model belongs to oil field equipment technical field, is specifically related to a kind of crude oil single well pipeline load-type automatic medicine adding apparatus.
Background technology
Oil exploitation is generally all carried out in the wild, and wild environment temperature Change is violent, and the temperature difference even can differ tens degree sooner or later sometimes.After mercury dropped, exploitation viscosity of crude out can increase, thereby causes its mobility variation, and crude oil is in petroleum pipeline course of conveying, can cause travelling speed to slow down and problem that pipeline internal pressure increases, this has brought very big inconvenience to the normal production in oil field.In order to increase the mobility of crude oil, staff can inject liquid conventionally in the crude oil of petroleum pipeline, thereby reduces viscosity of crude, increases its mobility.But existing adding method thereof needs first temporary close oil production equipment, opens valve topple over liquid by staff in petroleum pipeline, and then open oil production equipment.Existing adding method thereof exists cannot realize the problem of not shutting down dosing, needs manual dosing simultaneously, has reduced the production efficiency in oil field.
Utility model content
The purpose of this utility model is to provide a kind of crude oil single well pipeline load-type automatic medicine adding apparatus, and this device has solved existing adding method thereof cannot realize the problem of not shutting down dosing.
The technical scheme that the utility model adopts is, a kind of crude oil single well pipeline load-type automatic medicine adding apparatus, comprise drug-containing jar, in drug-containing jar, be provided with piston, the connecting rod that piston and stretches out drug-containing jar is connected, and driving piston to move up and down in drug-containing jar by bar, the part cover that connecting rod stretches out drug-containing jar has spring; The sidewall of drug-containing jar is connected with drug-feeding tube and drug discharging tube respectively, and the height of drug-feeding tube and drug discharging tube is lower than piston range place.
Feature of the present utility model is also,
On drug-feeding tube, be provided with flap valve a, on drug discharging tube, be provided with flap valve b.
The bottom of drug-containing jar is provided with base.
The top of connecting rod is connected with pressure cap.
On connecting rod, be connected with protective cover, protective cover covers spring and drug-containing jar.
The beneficial effects of the utility model are: by utilizing this device automatically to input liquid in petroleum pipeline; solve existing adding method thereof and cannot realize the problem of not shutting down dosing; simultaneously; during the dosing of this chemicals dosing plant, automatically move; do not need artificial dosing, in the normal production work that does not affect oil field, saved labour; thereby improved production efficiency, field produces unit has been had to higher practicality and economic worth.
Accompanying drawing explanation
Fig. 1 is the device schematic diagram of a kind of crude oil single well pipeline of the utility model load-type automatic medicine adding apparatus.
In figure, 1. pressure cap, 2. spring, 3. protective cover, 4. drug-containing jar, 5. connecting rod, 6. piston, 7. base, 8. drug-feeding tube, 9. flap valve a, 10. flap valve b, 11. drug discharging tubes.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, a kind of crude oil single well pipeline load-type automatic medicine adding apparatus, comprises drug-containing jar 4, and the bottom of drug-containing jar 4 is provided with base 7, and base 7 makes drug-containing jar 4 and ground stable connection, guarantees when this device is used not to be offset.In drug-containing jar 4, be provided with piston 6, the connecting rod 5 that piston 6 and stretches out drug-containing jar 4 is connected, and drives piston 6 to move up and down in drug-containing jar 4 by bar 5.The part cover that connecting rod 5 stretches out drug-containing jar 4 has spring 2, spring 2 provides power while rising for piston 6, piston 6 can be pumped, and on connecting rod 5, be connected with protective cover 3, protective cover 3 covers spring 2 and drug-containing jar 4, protect this device to avoid drenching with rain, thereby effectively increase the application life of this device; Meanwhile, the top of connecting rod 5 is connected with pressure cap 1, and pressure cap 1 has increased the contact area of this device with pumping unit horsehead, and the downforce of horse head is transmitted on connecting rod 5 smoothly.The sidewall of drug-containing jar 4 is connected with drug-feeding tube 8 and drug discharging tube 11 respectively, the height of drug-feeding tube 8 and drug discharging tube 11 is lower than piston 6 range places, on drug-feeding tube 8, be provided with flap valve a9, prevent that the liquid in drug-containing jar 4 is back to drug-feeding tube 8, on drug discharging tube 11, be provided with flap valve b10, prevent that the liquid in drug discharging tube 11 is back to drug-containing jar 4.
Using method of the present utility model is, when needs are during to petroleum pipeline dosing, first the drug discharging tube of this device 11 is connected with the oil pipeline of oil extraction in oil field tree, again drug-feeding tube 8 is connected with liquid conveyance conduit, then, by base 7 be fixed on pumping unit horsehead under, guarantee that horse head is pressed on the pressure cap 1 of this device in decline process.
The utility model utilizes pumping unit horsehead this feature that pumps, constantly the liquid in drug-containing jar 4 is pressed into petroleum pipeline, its course of work is, first, liquid flows into drug-containing jar 4 by drug-feeding tube 8, when horse head decline is pressed on pressure cap 1, drivening rod 5 and piston 6 together move downward, the spring 2 being simultaneously enclosed within on connecting rod 5 is compressed, along with the interior pressure of drug-containing jar 4 constantly increases, because flap valve has the unidirectional general character, flap valve a9 on drug-feeding tube 8 closes, flap valve b10 on drug discharging tube 11 opens, liquid in drug-containing jar 4 is just pressed into petroleum pipeline from drug discharging tube 11, when horse head rises, horse head and pressure cap 1 depart from, after not stressing, spring 2 starts to recover former length, drivening rod 5 and piston 6 move upward simultaneously, along with the interior pressure of drug-containing jar 4 constantly reduces, the flap valve a9 on drug-feeding tube 8 opens, and the flap valve b10 on drug discharging tube 11 closes, liquid in drug-feeding tube 8 is drawn into drug-containing jar 4, has just completed dosing process one time.When horse head declines again, just start dosing process again.
