Description
Technical field
The utility model field relates to a kind of technical field of oil field equipment, is specifically related to a kind of good antiscale property coating tubing.
Background technique
Along with the exploitation in oil field, oil well pipe is deepened year by year, the difficult cleaning tubing such as oil pipe tube wall incrustation, scale, salt crust, wax deposition, viscous crude accumulation increases year by year, this type of oil pipe because of can not get repair or repairing quality not high and cause waste and there are quality problems, add development cost.
At present for increasing oil recovery amount, generally adopt composition polymer as oil displacement agent on the market, these flooding method techniques are simple, and use the chemical agent displacement of reservoir oil very easily to cause fouling, alkali and sandstone formation react and produce soluble silicate, this salt and other arrive the combination of meeting of the calcium-magnesium-containing ion of oil well and the higher stratum water of salinity and cause fouling to be formed.Meanwhile, owing to recovering the oil, regional water and condition of water quality change cause stratum to produce surperficial incrustation scale, and corrosion ground product forms dirt, and the formation of these dirts can fill in silt oil pipe in a short time, and time serious, fouling and clogging oil recovery pipeline, causes oil well to stop production.Being applied to oil pipe anti-scaling anti-corrosive layer general thickness is at present 250 ~ 300mm, anti-scaling anti-corrosive poor-performing, and fouling can cause dirt erosion, oil pipe is bored a hole, causes huge loss to oil field.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency how overcoming prior art existence, provides a kind of good antiscale property coating tubing.The utility model product structure is stablized, and scale-preventing performance is high, extends oil pipe working life.
Technical solution of the present utility model is: a kind of good antiscale property coating tubing, comprise rigidity body and be positioned at rigidity body inner liner, described lining comprises anticorrosive coat and dirty proof layer, described anticorrosive coat adheres to described rigidity inner surface of tube body, described dirty proof layer is positioned on anticorrosive coat, described dirty proof layer is made up of upper strata and lower floor, described upper strata is provided with the surface layer of anti-adhesive, described surface layer directly contacts oil, described surface layer is polytetrafluoroethylene polymer coating, described polytetrafluoroethylene polymer is at least containing an alkyl vinyl ether, described lower floor is positioned on described anticorrosive coat, described lower floor is provided with (per) fluoropolymer coating and mica particles layer composition.
Described anticorrosive coat is tetrafluoroethylene and perfluoroolefin copolymer coating, and described perfluoroolefine is at least containing three carbon atoms.
Described anticorrosive coat thickness is no more than 25 microns, and described dirty proof layer thickness is 51-175 micron.
Described anticorrosive coat thickness at least 25 microns, described dirty proof layer thickness is 635-6350 micron.
Described anticorrosive coat can be (per) fluoropolymer coating.
Described dirty proof layer and anticorrosive coat are prepared from all in the molten state.
The utility model advantage is structural stability, has ornamental and wettability preferably, and effectively reduce fouling rate, antiseptic property also increases greatly, has good preventing function to the oil pipe dirt erosion that chemical agent causes.The utility model adopts teflon and (per) fluoropolymer to be prepared from as material, high temperature resistant, has relatively stable shape, and decay resistance increases.The utility model fouling rate reduces 40%, adds the working life of oil pipe, effectively makes up the defect of prior art, meets oil well demand.
