Abstract
The utility model relates to a downhole pipeline anti-corrosion bracelet type positive pole which comprises a positive pole main body, wherein two ends of the positive pole main body are fixed on a clamp tool which is fastened with an oil pipe through top threads. The downhole pipeline anti-corrosion bracelet type positive pole has the advantages that a pipeline is protected to be resistant to corrosion through sacrifice of the positive pole, effectively protects the pipeline through sacrifice of the positive pole, improves the anti-corrosion environment outside the pipeline simultaneously, can be applied to anti-corrosion of the conveying pipeline of an oil-water well, can prolong the service life of the pipeline of the oil-water well in an effective mode, and is stable and reliable in performance.
Description
Technical field
The utility model relates to the engineering pipeline anti-corrosive apparatus in oil extraction in oil field and the water filling, specifically the anticorrosion bracelet type of a kind of down-hole pipe anode.
Background technology
Prolongation along with the relatively poor produced-water reinjection of the continuous growth of the oil field development time limit and water quality and oil well and water injection well duty cycle, cause each pipeline of down-hole more serious fouling corrosion phenomenon all to occur, dispensing and oil recovery effect have been had a strong impact on, even cause normally deblocking and can't extracting of downhole tool, affect oilfield safety production and economical operation.
Summary of the invention
In order better to address the above problem, the utility model provides the anticorrosion bracelet type of a kind of down-hole pipe anode.Function with anode loss protection pipeline corrosion protection can effectively be protected pipeline corrosion protection, improves simultaneously the outer anticorrosion environment of pipeline.
The technical solution of the utility model is: the anticorrosion bracelet type of a kind of down-hole pipe anode, comprise anode body and jig, there are some elongated guide rods described anode body inside, and the two ends of guide rod are separately fixed on the jig, radially screw is arranged on the jig, and jackscrew and oil pipe in the screw are fastening.
As preferably, the material of anode body is aluminium zinc indium evanohm, contacts with oil pipe the oil pipe polarization potential is lower than-0.85V.
[0006]In order to bring into play better the antiseptic effect of sacrificial anode, the elongated guide rod of described anode body inside and the radially screw on the jig are for circumferentially uniform; And described anode body and jig are that bracelet type latch closure is on pipeline.
The beneficial effects of the utility model are: owing to adopt technique scheme; the two is fixedly connected with anode and jig by welding manner; what guarantee anode and pipeline is connected effect and electric conductivity; simultaneously according to oil-water well pipeline external diameter; anode and the jig of coupling corresponding size link to each other with the oil-water well pipeline, effectively bring into play anode loss protection pipeline corrosion protection effect; thereby prolong the application life of pipeline, have reliability and stability.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of Fig. 1 Anodic main body:
Fig. 3 is jig generalized section among Fig. 1.
1-jig among the figure, 2-jackscrew, 3-anode body, 4-oil pipe.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Extremely shown in Figure 3 by Fig. 1, the anticorrosion bracelet type of this down-hole pipe anode, comprise anode body 3 and jig 1 and jackscrew 2, there are some elongated guide rods described anode body 3 inside as shown in Figure 2, the two ends of guide rod are weldingly fixed on respectively on two jigs 1, on each jig 1 radially screw is arranged, jackscrew 2 in the screw is fastening with oil pipe 4 or downhole tool, such as Fig. 1 and shown in Figure 3, make anode body 3 and downhole tool, the oil-pipe external wall electric conduction connects, and consisting of becomes anode by the relatively low metal material of current potential, downhole tool, oil pipe, sleeve pipe is a macroscopical battery of negative electrode, need not power supply, corrosion is reduced or stop, reaching the purpose that control cathode is corroded.
As preferably, the material of described anode body 3 is aluminium zinc indium evanohm, contacts with oil pipe the oil pipe polarization potential is lower than-0.85V, rely on the lower anode of current potential constantly the electric current that produces of corrosion dissolution protect downhole tool, oil pipe or sleeve pipe.
In order to bring into play better the antiseptic effect of sacrificial anode; the elongated guide rod of described anode body 3 inside and the radially screw on the jig 1 are for circumferentially uniform; guarantor's positive potential is even, and described anode body 3 and jig 1 be bracelet type latch closure on pipeline, make pipe surface form complete topping.
The anticorrosion bracelet type of this down-hole pipe anode has sacrificial anode; the anti-corrosion function of protection pipeline; can greatly prolong the application life of the downhole tool such as oil-water well and the pipeline that is connected, improve its stability, can be applicable to oil well, poly-displacement of reservoir oil well, ternary displacement of reservoir oil well, strong fouling well etc.
