Abstract
The utility model provides an antiseptic corrosion inhibitor feeding device for a CO2 production well, and relates to the technical field of oil field engineering, in particular to the technical field of corrosion prevention for on-site inhibitor feeding antiscaling oil and gas well CO2 resistant production wells. An inhibitor storage barrel, an electric appliance control box and a five-way valve are respectively arranged in a multilayer heat preservation box, and the control signal output end of the electric appliance control box is connected with a safety control valve. Due to the adoption of the multilayer heat preservation box, the temperature of an inhibitor can be kept within the range from -30 DEG C to 40 DEG C, and it can be guaranteed that the feeding device also can normally work even in the low-temperature environment at the temperature being -30 DEG C. The antiseptic corrosion inhibitor feeding device is further provided with a backflow prevention valve and an electrode point pressure meter, overpressure can be effectively prevented, and the safety performance of the device is further guaranteed.
Description
Technical field
The utility model relates to oilfield engineering technical field, especially for the anti-CO of on-the-spot dosing antiscale Oil/gas Well
2the aseptic technic field of extraction well.
Background technology
In Oil/gas Well development process, extensively exist CO
2, make metallic conduit and hardware that early stage corrosion failure occur, cause shorten the application life of pipeline and equipment.CO
2corrosion failure is the one of the main reasons that in oil gas well mining and course of conveying, metal material destroys, if anticorrosion technique can fully be applied, 30%～40% of the loss causing due to corrosion just can be retrieved.Therefore, prevent or reduce CO
2the method of corrosion, becomes the problem that people pay close attention to.
Practice at home and abroad experience shows, corrosion inhibiter resist technology as a kind of economy, effectively and the metal erosion control method of highly versatile, be particularly suitable for applying in Oil/gas Well and gathering system.Therefore, the anti-CO of exploitation Oil/gas Well
2, the corrosion inhibiter of corrosion becomes and becomes more and more important.
Utility model content
The utility model object be propose a kind of be applicable to Oil/gas Well scene, can effectively avoid metallic conduit and hardware that the CO of early stage corrosion failure occurs
2the corrosion inhibitor chemicals dosing plant of extraction well.
The utility model comprises a multi-layer heat preserving casing, in described multi-layer heat preserving casing, medicine storing drum is set respectively, electric appliance control box and five-way valve, control signal output at electric appliance control box connects Safety control valve, the outlet of described medicine storing drum is connected with the entrance point of anticorrosion injection pump by strainer, one end is set on multi-layer heat preserving casing at multi-layer heat preserving box inside, the other end is at the drain pipe in multi-layer heat preserving casing outside, on described five-way valve, connect respectively the port of export of anticorrosion injection pump, the output of Safety control valve, electrode points pressure meter, atmospheric valve and the anti-valve that backflows, the described anti-other end of valve and the drain pipe end of multi-layer heat preserving box inside of backflowing is connected.
The utility model can be filling for CO in medicine storing drum
2anticorrosion required multiple acid medium medicament, adopts electric appliance control box accurately to control chemical feeding quantity and dosing frequency.The utility model, owing to having adopted multi-layer heat preserving casing, can make medicament remain on-30 ℃ within the scope of 40 ℃, even if can guarantee that chemicals dosing plant also can normally work under the low temperature environment of-30 ℃.Drain pipe of the present utility model can adopt high-pressure hose to draw, and conveniently draws connection, and simultaneously due to outdoor low temperature environment impact, the parts such as high-pressure hose are also designed with insulation and companion's hot merit energy, guarantee that tube fluid there will not be frozen block phenomenon.In addition, this device adopts five-way valve to make the connection of pipeline convenient, the convenience while simultaneously also having guaranteed maintenance.The utility model has also designed anti-backflow valve and electrode points pressure meter, can effectively prevent superpressure, further to guarantee the security performance of device.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, in multi-layer heat preserving casing 1, be respectively arranged with medicine storing drum 2, electric appliance control box 4 and five-way valve 9 etc., at the control signal output Safety control valve 6 of the microcomputer controller 5 of electric appliance control box 4.
Medicine storing drum 2 is fixed on the support in multi-layer heat preserving casing 1, and the outlet of medicine storing drum 2 is connected with the entrance point of anticorrosion injection pump 3 by strainer 12.
On multi-layer heat preserving casing 1, arrange one end in multi-layer heat preserving casing 1 inner side, the other end is at the drain pipe 11 in multi-layer heat preserving casing 1 outside.
The output of the port of export of anticorrosion injection pump 3, Safety control valve 6, electrode points pressure meter 7, atmospheric valve 13 and the anti-valve 10 that backflows are connected on five interfaces of five-way valve 9, and prevent the backflowing other end of valve 10 and drain pipe 11 ends of multi-layer heat preserving casing 1 inner side are connected.
