Abstract
An oil pipe with dissolution coating modification high polymer materials for entire corrosion resistance belongs to the field of oil extraction equipment of petroleum machinery. The oil pipe with the dissolution coating modification high polymer materials for entire corrosion resistance is composed of a coupling, a long male joint, a long female joint, the oil pipe, a short male joint and a short female joint and is characterized in that the inner walls and the outer walls of the oil pipe, the long male joint, the long female joint, the short male joint and the short female joint are provided a corrosion resistance layer which is made from the dissolution coating modification high polymer materials. The coupling, the long male joint, the long female joint, the short male joint and the short female joint are made of stainless steel. Compared with the existing oil pipes, the corrosion resistance layer which is made from the dissolution coating modification high polymer materials and arranged on the inner walls and the outer walls of the oil pipe, the long male joint, the long female joint, the short male joint and the short female joint can be used for effectively preventing corrosion and scale and utilized in cooperation with the coupling, the long male joint, the long female joint, the short male joint and the short female joint which are made of stainless steel to enable the inner wall and the outer wall of the oil pipe to have a performance of no corrosion resistance blind area, so that requirements of the corrosion resistance performance of oil pipes of existing oil extraction wells can be perfectly met.
Description
Affiliated technical field
The utility model belongs to petroleum machinery oil production equipment field, and what be specifically related to is a kind of molten full antisepsis oil pipe of modification macromolecular material that is coated with.
Background technology
When oil and gas development, oil well pipe bears the synergy of multiple load and different corrosive mediums at work, in some oil well, well liquid contains salt solution, carbon dioxide, hydrogen sulfide or corrosion-causing bacteria, and the existence of these corrosive mediums or corrosion-causing bacteria greatly reduces application life of oil well pipe.Therefore, for satisfy the large pump in oil field, adopt by force, dark well recovery hole condition demand, processing and manufacturing has the oil pipe of antiseptic property, is the application life that extends oil well pipe, reduces the key measure of oil extraction in oil field cost.
Summary of the invention
In order to improve the oil pipe anti-corrosive performance, the utility model provides a kind of molten technical scheme that is coated with the full antisepsis oil pipe of modification macromolecular material, and the technical program is simple in structure, is well positioned to meet existing producing well to the requirement of tube inner wall antiseptic property.
The utility model is to realize like this, a kind of molten full antisepsis oil pipe of modification macromolecular material that is coated with, it is made of box cupling, long pin and box sub, oil pipe, short pin and box sub, it is characterized in that, oil pipe, long pin and box sub, short pin and box sub inwall and outer wall have the molten modification macromolecular material anticorrosive coat that is coated with.
Described box cupling, long pin and box sub, short pin and box sub are stainless steel.
Described long pin and box sub and short pin and box sub one end are internal thread, and the other end is external screw thread.
Described box cupling has internal thread, and box cupling, long pin and box sub, oil pipe, short pin and box sub connect by engage thread.
