Abstract
The utility model discloses a continuous automatic chemical-feeding device for oil wells, which is composed of a liquid inlet valve, a liquid storage tank, a liquid outlet valve, and a cylinder body. A flow-control short joint is connected to the lower part of the cylinder body, a needle valve is inserted in the flow-control short joint, an internal thread on the lower end of the flow-control short joint is connected with a control pipe plug, an external thread is connected with a triplet, and a pressure balance pipe is arranged between the liquid storage tank and the triplet. The utility model has the advantages of continuous and automatic chemical feeding, high precision of measurement of chemical, even medicine adding, low labor intensity, low cost, etc.
Description
The utility model relates to the continuous automatic medicine adding apparatus of a kind of oil well.
Along with after oil field development enters middle and high Water-cut Period, corrode more and more serious, for slowing down the corrosion of oil well casing, oil jacket and surface line, generally take regularly to add the method for corrosion inhibiter to the individual well oil sets annular space, its mode has two kinds: artificial dosing method and special-purpose vehicle dosing method.These two kinds of methods all adopt periodically instantaneous to the oil sets annular space injection, artificial dosing method medicament measuring accuracy height, but labour intensity is big; Though special-purpose vehicle dosing method has reduced labour intensity, the metering of dosing is again less than assurance; In addition, these two kinds of adding method thereofs all have the shortcoming of a maximum, be exactly that the corrosion inhibiter utilization rate is not high, drug effect is not in full use, promptly all returned out ground in medicament 2-4 days, in the dosing cycle corrosion inhibiter fluctuation very big, can't keep continuing, effective corrosion inhibitors concentration, the medicament waste is big, and the dosing effect is not ideal enough.
The purpose of this utility model just provides the continuous automatic medicine adding apparatus of a kind of oil well.
The purpose of this utility model is achieved in that this device is made up of feed liquor valve, liquid reserve tank, liquid valve, cylindrical shell, be connected to the flow-control pipe nipple in the cylindrical shell bottom, flow-control pipe nipple hollow, its inner and upper is an infundibulate, needle-valve is housed on it, needle-valve top is wiper block, the bottom is a control rod, control rod inserts in the flow-control pipe nipple, the lower end internal thread of flow-control pipe nipple connects the control plug, external screw thread connects threeway, and plug also is a hollow, between liquid reserve tank and threeway pressure-equalizing pipe is housed.Be with magnetic driver on the flow-control pipe nipple.
The utlity model has following advantage: 1, device does not need extraneous any power, can realize to the continuous Automatic Dosing of oil sets annular space, and the medicament accurate measurement, dosing is even, and labour intensity is little; 2, cost is low, and is simple to operate, and easy care is suitable for open-air various environment.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1: the continuous automatic medicine adding apparatus structural representation of oil well;
Among the figure: 1-feed liquor valve, 2-liquid reserve tank, 3-liquid valve, 4-cylindrical shell, 5-needle-valve, 6-magnetic driver, 7-flow-control pipe nipple, 8-control plug, 9-well head big four, 10-balance pipe, 11-fixed support, 12-threeway;
As shown in Figure 1, the continuous automatic medicine adding apparatus of oil well is by liquid reserve tank 2, cylindrical shell 4 is formed, liquid reserve tank 2 is provided with feed liquor valve 1 and liquid valve 3, cylindrical shell 4 adopts the screen magnet material, be connected to flow-control pipe nipple 7 in cylindrical shell 4 bottoms, flow-control pipe nipple 7 hollows, its inner and upper is an infundibulate, needle-valve 5 is housed on it, needle-valve 5 tops are wiper block, the bottom is a control rod, and control rod inserts in the flow-control pipe nipple 7, utilizes rod to realize flow-control with the different apertures on the pipe nipple, be with magnetic driver 6 on the flow-control pipe nipple 7, when needle-valve 5 produced obstruction with flow-control pipe nipple 7, as long as move up and down magnetic driver 6, magnetic driver 6 drive needle-valves moved up and down in flow-control pipe nipple 7 and carry out conducting.The lower end internal thread of flow-control pipe nipple 7 connects control plug 8, external screw thread connects threeway 12, plug 8 also is a hollow, it can select different internal diameters to regulate the flow of soup as required, between liquid reserve tank 2 and threeway 12, pressure-equalizing pipe 10 is housed, pressure-equalizing pipe is to make well head pressure and fluid reservoir internal pressure keep balance, prevents that medicament from being withstood by gas.
The continuous automatic medicine adding apparatus of oil well is installed in parallel in production tree one side, and top is fixing by fixed support 11, and the lower end medicine outlet links to each other with the sleeve valve of sebific duct with well head big four 9 sides.Turn off sleeve valve during use earlier, open the dosing valve of fluid reservoir top, after a cover of storing in waiting jar has pressed, medicament is added in the fluid reservoir, shut the dosing valve, open liquid valve 3 and sleeve valve, medicament is by deadweight, arrive in the cylindrical shell,, arrive in the sebific duct by the dual control of needle-valve with the control plug, sebific duct communicates with the well head sleeve pipe, thereby make medicament flow to oil sets annular space, and final settlement fully mix below producing fluid level with treating output liquid.During oil recovery, mixed liquor is drawn in the gathering line on ground through oil well pump by oil pipe.This covering device has been realized medicament under the condition of no exterior power, to the continuous Automatic Dosing of oil sets annular space.
