Background technology
The utility model relates to the petroleum pipeline that oil exploitation is used, and more particularly, is a kind of petroleum pipeline that comprises pipeline, oil pipe and the sleeve pipe used in the oil field.
At present in the various pipelines that petroleum industry is used, producing well is used coating wax control oil pipe, coating antiseptic oil pipe that water injection well is used and nickel plating antisepsis oil pipe are at the steel for pipe frame plastic pipe of carrying various chemical mediators, plastic pipe, stainless steel tube, glass reinforced plastic pipe etc.All there are some shortcomings in above-mentioned these pipelines: (1) producing well is short with the coating life of coating wax control oil pipe, can be blocked oil well pump by the decortication after the sucker rod wearing and tearing: the coating antiseptic oil pipe that (2) water injection well is used, coating life is short, decortication is blocked up the stratum with injecting after water injects the stratum, there is pin hole on nickel plating antisepsis oil pipe surface, corrosion-resistant, the cost height, fouling is serious; (3) the pipeline cost height of the various chemical mediators of transportation, bearing capacity is low, bad mechanical property, what the high-low temperature resistant alternation was not produced wears out.Above-mentioned these shortcomings cause the oil field development cost to increase, and maintenance load is big, and the maintenance cost height influences field output, and the pipe material product model is many, and is wide in variety, are difficult for buying and management.
The purpose of this utility model is the shortcoming that overcomes existing petroleum pipeline, proposes the multi-functional petroleum pipeline that a kind of function is many, price is low, the life-span is long.
Petroleum pipeline of the present utility model is to be had the body of screw thread and constituted by the box cupling that screw thread links together with it by two ends.
Described inboard wall of tube body oozes one deck infiltration layer earlier, plates two-layer coating again in layer surface, and tube wall is impregnated with one deck infiltration layer, layer surface spraying one deck coating; Described box cupling, inwall have one deck infiltration layer, and outer wall oozes one deck infiltration layer earlier, and layer surface sprays one deck coating again, and the joint of two tubes in box cupling is provided with high strength, corrosion resistant excluder ring up and down.
Petroleum pipeline described in the utility model comprises oil pipe, sleeve pipe, sucker rod and the steel pipe of carrying various media, and pipeline connects by box cupling or directly welding.
Described body and screw threads of coupler comprise that tapered button, square button or triangle buckle.
Described tube wall coating material is selected from and comprises in Petropols, epoxy phenolics, alkyd resin, epoxide coal bituminous, the powdery paints any.Spraying method: with above-mentioned macromolecule dissolution in organic solvent (comprising dimethylbenzene, n-butanol, acetone, ethylenediamine), solid content is greater than 50%, after electrostatic spraying or pneumatic spraying, toast 60 minutes film-formings at 180-250 ℃, outer wall will spray and two of cured paint films more than the circulation at least, every time thickness is greater than 15 μ m, and sprayed coating thickness is 30-100 μ m.
Described infiltration layer comprises boride layer or nitriding layer, and alloying layer thickness is 4-8 μ m, and oozing temperature is 550-600 ℃.
Described coating makes two bites at a cherry, be anode coating for the first time, be envelope pin hole antiscale layer for the second time, each thickness of coating is more than the 12-18 μ m, coating material is nickel, phosphorus, zinc, magnesium, polytetrafluoroethylene (PTFE), graphite, can be the compound plating of above-mentioned six kinds of materials, also can be the mixing plating of two or more material.
Describedly only carry out external coating and inside and outside infiltration layer, do not carry out coating and handle by hoop.
The material of described excluder ring comprises polytetrafluoroethylene (PTFE) or the corrosion-resistant and inner rubber that is equipped with steel frame.
Major advantage of the present utility model:
The utility model petroleum pipeline has eight functions: anticorrosion, good antiscale property, anti-wax deposition, anti-400 ℃ of high temperature, lubricating and wear-resisting damage, high strength, high rigidity, screw thread have superpower outstanding loading capability, be the pipeline of oil transportation, water delivery and defeated various chemical mediators and chemical products, this pipeline can be used in the oilfield, in the water injection well in oil fields and in the pipe network and heat exchanger of defeated various liquid.
In sum, the utlity model has following major advantage:
1. the performance of interior coating is good, and price is low, and free of pinholes is wear-resisting, and is lubricated, anticorrosion, antiscale, and wax control, the life-span is long, does not peel;
2. the good physical and chemical properties of external coating, price is low, the corrosion of ability oilfield, the quiet liquid of well annular space, the life-span coupling with inwall can not cause waste;
3. box cupling and oil pipe screw thread are through after oozing processing; the suspended load ability of its screw thread increases by 50%, can prolong the life-span of oil pipe screw thread, and screw thread has the excluder ring protection simultaneously; make high pressure water injection or oil recovery working fluid not contact, avoid the damage of the weakest position of oil pipe one screw thread with screw thread.
