Abstract
The utility model provides a corrosion and scale inhibition tube which is mainly composed of an outer tube, a sieve tube, a medicinal powder tube and a medicinal powder. The outer tube is arranged on the external part of the corrosion and scale inhibition tube; the medicinal powder tube is fixed in the outer tube; the medicinal powder are arranged in the medicinal powder tube; and the sieve tube is mounted on the medicinal powder tube. The corrosion and scale inhibition tube has the advantages of simple and reliable device, no movable part, no need of maintenance, large suitable temperature range, high efficiency of corrosion and scale inhibition, easy installation, long service cycle, saved operational cost and no pollution to the oil layer.
Description
Technical field:
The present invention relates to the corrosion-mitigation scale-inhibition device of a kind of oil gas with oil well downhole production tubing string.
Background technology:
Usually run into the problem of oil well down-hole string corrosion and scaling in oil gas field production development process.The reason that causes oil well pipe surface corrosion fouling generally is the liquid salinity height of output.The dirt type depends on the content of different ions in the liquid.At present; the method of inhibition or corrosion of solution steel surface and fouling is to select inert metal, cathodic protection in field produces; regularly inject the liquid corrosion inhibiter, change tubing string etc., in general, these methods all exist complex process, effect is poor, cost is high shortcoming.Patent ZL200620119399 discloses a kind of oil gas field oil well down-hole corrosion-mitigation scale-inhibition device, and complex structure is installed trouble, and can only be adopted the liquid corrosion inhibiting and descaling agent, is not suitable for long-term use.
Summary of the invention:
The purpose of this utility model is to avoid above-mentioned deficiency and a kind of corrosion-mitigation scale-inhibition pipe of providing.Can overcome the technical problem of regular injection liquid corrosion inhibiting and descaling agent, directly be connected with tail pipe under the pump, the solid corrosion and scale inhibitor of packing into is fit to long-term the use.
The purpose of this utility model is achieved in that the corrosion-mitigation scale-inhibition pipe, mainly is made up of outer tube, screen casing, medicinal powder pipe, medicinal powder, and corrosion-mitigation scale-inhibition pipe outside is an outer tube, is fixed with the medicinal powder pipe in the outer tube, in the medicinal powder pipe medicinal powder is housed, and screen casing is installed on the medicinal powder pipe.The two ends of medicinal powder pipe are fixed dam, and fixed dam is fixed on the outer tube wall, locate the outer wall that inside pipe wall is made the medicinal powder pipe, and screen casing is installed on the baffle plate of corrosion-mitigation scale-inhibition pipe bottom.
The purpose of this utility model can also realize like this: the corrosion-mitigation scale-inhibition pipe, and the sealed tube of medicinal powder Guan Weiyu outer concentric tube, the inwall of outer tube is made the outer wall of medicinal powder pipe, and the inwall any place of medicinal powder pipe has sieve aperture.
Advantage of the present invention is: install simple and reliablely, movement-less part does not need maintaining, and the Applicable temperature scope is big, reduces burn into fouling rate height, installs simply, and life cycle is long, has saved operating cost, has stopped oil layer pollution etc.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model embodiment 1.
Accompanying drawing 2 is the structural representation of the utility model embodiment 2.
1 is that joint, 2 is outer tube among the figure, and 3 is baffle plate, and 4 is medicinal powder, and 5 is screen casing, and 6 is the medicinal powder inside pipe wall, and 7 is sieve aperture, and 8 is the medicinal powder pipe.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment 1
The corrosion-mitigation scale-inhibition pipe mainly is made up of outer tube 2, screen casing 5, medicinal powder pipe 8, medicinal powder 4, and corrosion-mitigation scale-inhibition pipe outside is an outer tube 2, and the outer tube two ends are joint 1, are fixed with medicinal powder pipe 8 in the outer tube 2, and medicinal powder 4 is housed in the medicinal powder pipe 8, and screen casing 5 is installed on the medicinal powder pipe 8.The two ends of medicinal powder pipe 8 are fixed dam 3, and fixed dam 3 is fixed on outer tube 2 inwalls, and outer tube 2 inwalls are made the outer wall of medicinal powder pipe 8, and screen casing 5 is installed on the baffle plate 3 of corrosion-mitigation scale-inhibition pipe bottom.
Corrosion-mitigation scale-inhibition pipe, medicinal powder pipe 8 are the sealed tube concentric with outer tube 2, and the inwall of outer tube 2 is made the outer wall of medicinal powder pipe 8, and medicinal powder inside pipe wall 6 any places have sieve aperture 7.
The Applicable temperature scope reduces corrosion and reaches 60%---95% between 50---90 degree centigrade, and knot anti-corrosion, scale-inhibiting rate directly is connected with tail pipe under the pump more than 95%, and solid corrosion and scale inhibitor Na packs into
