Abstract
The utility model relates to the technical field of oil field oil recovery, in particular to an automatic and continuous well head reagent adding device. The automatic and continuous well head reagent adding device comprises a reagent tank body, a support, a liquid level meter, a tank body outlet, an emptying valve, a pressure gage, a reagent adding hole, a filter screen, a breathing pipe, a liquid outlet pipe, a reagent adding valve and a water nozzle. A breathing balance system is formed by the emptying valve, the liquid outlet pipe, the breathing pipe, the reagent adding hole and the tank body outlet, the balance of the pressure of a tank body and the pressure of an oil well is ensured, and smooth liquid adding is ensured. It is ensured that a reagent automatically flows in an oil well sleeve pipe and is fully mixed with liquid in the well through the height pressure difference existing between the reagent and the liquid, and the effect of lowering the viscosity is achieved. According to the automatic and continuous well head reagent adding device, automatic and continuous reagent filling is achieved, the corrosion effect of the reagent is performed to the maximum, and the yield of the oil well is improved. The automatic and continuous well head reagent adding device has the advantages that the reagent is added by the device in a sealed mode, and therefore pollution caused by overflow of the reagent is avoided.
Description
Technical field
The utility model relates to oil extraction in oil field technical field, is specifically related to a kind of well head auto continuous chemicals adding apparatus.
Background technology
Oil well in process of production, according to the different characteristics of produced liquid in oil well, need to add corresponding medicament, solves oily thick wax deposition, well polished rod and bears that load is large, hot strength is large, the problems such as wax card polished rod.Started in recent years to take the method for artificial regularly dosing to implement artificial viscosity reduction, wax control, the average daily fluid production rate of individual well reaches 12.9 sides by 10.2 sides.But it is unbalanced that the method for at present artificial well head medicine-adding exists chemical feeding quantity to flow into the pit shaft time; The fluctuation of individual well daily fluid production rate is larger, between 3-15 side; And still there will be oily thick wax deposition the latter stage in dosing cycle and cause bar card, bar to break.The disconnected frequency of the thick paraffin-troubled well bar of oil kelly of the regular dosing of two ore deposit 2009-2010 of recovering the oil is 16 wells times/year.These still all affect the further lifting of production crew's management level largely.
Summary of the invention
The technical problems to be solved in the utility model is how to overcome the deficiency that prior art exists, and a kind of well head auto continuous chemicals adding apparatus is provided, and by medical infusion principle and concentric double pipe principle, has solved medicine storing pot pressure balance and flow velocity problem.
Technical solution of the present utility model is: a kind of well head auto continuous chemicals adding apparatus, comprise medicine storing pot body and support, and it is characterized in that: also comprise atmospheric valve, drain pipe, respiratory siphon, medicine feeding hole and tank body outlet; Described drain pipe end is provided with dosing valve, water nozzle; Described tank body is positioned on support, described tank body upper end is provided with medicine feeding hole, described atmospheric valve is positioned at described tank body left upper end, described respiratory siphon and drain pipe are distributed in described tank interior side by side, described tank body lower-left end is provided with tank body outlet, described respiratory siphon end is directly connected with described tank body outlet, and described drain pipe stretches out tank body part and is positioned at described tank body outlet inside.
