Abstract
The utility model provides a water injection well medicine adding device, and belongs to devices for oil field production. The device comprises an outer cylinder body, a medicine chest body is fixed on an inner side of the outer cylinder body and provided with a medicine out holes, a bottom sub is mounted at the upper end of the outer cylinder body, and an emptying pipe is communicated with a side face of the lower portion of the outer cylinder body and provided with a valve. When used, the water injection well medicine adding device can be mounted on a wellhead, antiseptic scale inhibition treatment agent is added to a downhole through the medicine chest body, corrosion and scale formation of downhole oil pipes can be effectively lightened, the service life of the oil pipes is prolonged, and normal production of oil fields is ensured. The water injection well medicine adding device is simple and reasonable in structure, and convenient to use.
Description
Technical field
The utility model provides a kind of field produces device, especially a kind of chemicals dosing plant of water injection well.
Background technology
At present, on the water injection well in oilfield process, also do not inject the device of anti-corrosion, scale-inhibiting treatment agent to the down-hole, cause the down-hole oil tube corrosion and scaling serious, oil pipe is short application life, affects the oil field and normally produces.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of water injection well chemicals dosing plant, for add the anti-corrosion, scale-inhibiting treatment agent to the down-hole, to alleviate the corrosion and scaling of down-hole oil tube.
The utility model is achieved in that the water injection well chemicals dosing plant, and it has outer cylinder body, and the outer cylinder body inboard is fixed with the medicine-chest body, on the medicine-chest body medicine outlet hole is arranged, and the upper end of outer cylinder body is equipped with plug, and the lower side of outer cylinder body is communicated with blow-down pipe, and valve is arranged on the blow-down pipe.
Adopt the water injection well chemicals dosing plant of said structure, can be installed in during use on the well head, add the anti-corrosion, scale-inhibiting treatment agent to the down-hole by the medicine-chest body, can effectively alleviate the down-hole oil tube corrosion and scaling, the application life that has prolonged oil pipe is short, has guaranteed that the oil field normally produces.And simple and reasonable, easy to use.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
As shown in drawings, the water injection well chemicals dosing plant of the utility model, it has outer cylinder body 5, the outer cylinder body inboard is fixed with medicine-chest body 3, and medicine outlet hole 4 is arranged on the medicine-chest body, and the upper end of outer cylinder body is equipped with plug 1, the lower side of outer cylinder body is communicated with blow-down pipe 6, and valve 7 is arranged on the blow-down pipe.
Plug is installed in the upper end of outer cylinder body by screw thread.The connecting portion of outer cylinder body and medicine-chest body can be protruding, to expose medicine outlet hole.
During use, the vertical siphunculus 8 on the screw thread by the outer cylinder body lower outside and the little four-way 9 of well head is installed together.Back out plug, the anti-corrosion, scale-inhibiting treatment agent is sent in the medicine-chest body, the plug of screwing on again.The anti-corrosion, scale-inhibiting treatment agent will flow out from the medicine outlet hole on the medicine-chest body, falls into the down-hole.
The medicine-chest body can be fixed together by screw thread and outer cylinder body, the upper end of medicine-chest body can be fluted 2, and tool inserting is rotated the medicine-chest body at groove, changes the length that the medicine-chest body stretches out downwards, namely change the quantity that medicine outlet hole exposes, can change the speed that the anti-corrosion, scale-inhibiting treatment agent flows out.On the outer cylinder body inwall scale can be arranged, with the length numerical value that shows that the medicine-chest body stretches out downwards.
Open the valve on the blow-down pipe, effluent air in the well can be discharged.
