Abstract
The invention discloses a steel pipe for geological drilling. The steel pipe comprises a steel pipe body, a 42MnMo7 coating, an SiCp/Al-Cu-Mg composite layer, a 7E04 aluminum alloy coating and a 100V-Cr-Mo coating, wherein the outer surface of the steel pipe body is sequentially provided with the 42MnMo7 coating, the SiCp/Al-Cu-Mg composite layer, the 7E04 aluminum alloy coating and the 100V-Cr-Mo coating from inside to outside. In such a way, the steel pipe is favorable in internal and external pressure resistance and excellent in wear resistance, so that the reliability of the steel pipe during deep well and extradeep well drilling is ensured.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of steel pipe for geological drilling.
Background technology
Steel pipe is the strip steel of a kind of hollow, a large amount of pipelines being used as conveyance fluid, such as oil, natural gas, water, coal gas, steam etc., it addition, when doing curved, torsional strength and being identical, lighter in weight, so being also widely used in manufacture machine components and engineering structure.
Steel pipe can be divided into two big classes by production method: seamless steel pipe and seamed steel pipe, seamed steel pipe is referred to as steel pipes with straight.Seamless steel pipe can be divided into by production method: hot seamless tube, drawn tube, precision tube, hot-expanding pipe, cold spinning pipe and extruded tube etc..Seamless steel pipe Fine Steel Casting iron or steel alloy are made, have hot rolling, cold rolling (pulling out) point.Seamless steel pipe can be used for liquid air-pressure duct and the gas pipeline etc. of various industry.Welded pipe line can be used for aqueduct, gas piping, caliduct, electrical equipment pipeline etc..
But, the anti-inside and outside pressure performance of currently used common steel tube and anti-wear performance all can not meet the demand of geological drilling.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steel pipe for geological drilling, and anti-inside and outside pressure is functional, and anti-wear performance is good, thus ensure that its reliability when deep-well and ultradeep well creep into.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of steel pipe for geological drilling, including: steel pipe body, 42MnMo7 coating, SiCp/Al-Cu-Mg composite layer, 7E04 aluminum alloy coating and 100V-Cr-Mo coating, the outer surface of described steel pipe body is disposed with described 42MnMo7 coating, described SiCp/Al-Cu-Mg composite layer, described 7E04 aluminum alloy coating and described 100V-Cr-Mo coating outward from interior.
In a preferred embodiment of the present invention, described steel pipe body is 37Mn5 steel body.
In a preferred embodiment of the present invention, the thickness of described SiCp/Al-Cu-Mg composite layer is 1 ~ 2mm.
In a preferred embodiment of the present invention, the thickness of described 100V-Cr-Mo coating is 0.5 ~ 1mm.
The invention has the beneficial effects as follows: the present invention resists inside and outside pressure functional, and anti-wear performance is good, thus ensure that its reliability when deep-well and ultradeep well creep into.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the present invention structural representation for steel pipe one preferred embodiment of geological drilling；
In accompanying drawing, the labelling of each parts is as follows: 1, steel pipe body, and 2,42MnMo7 coating, 3, SiCp/Al-Cu-Mg composite layer, 4,7E04 aluminum alloy coating, 5,100V-Cr-Mo coating.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of steel pipe for geological drilling, including: steel pipe body 1,42MnMo7 coating 2, SiCp/Al-Cu-Mg composite layer 3,7E04 aluminum alloy coating 4 and 100V-Cr-Mo coating 5, the outer surface of described steel pipe body 1 is disposed with described 42MnMo7 coating 2, described SiCp/Al-Cu-Mg composite layer 3, described 7E04 aluminum alloy coating 4 and described 100V-Cr-Mo coating 5 outward from interior.
In the present invention, described steel pipe body 1 is 37Mn5 steel body.
In the present invention, the thickness of described SiCp/Al-Cu-Mg composite layer 3 is 1 ~ 2mm.
In the present invention, the thickness of described 100V-Cr-Mo coating 5 is 0.5 ~ 1mm.
The present invention provides the benefit that for the steel pipe of geological drilling: the present invention resists inside and outside pressure functional, and anti-wear performance is good, thus ensure that its reliability when deep-well and ultradeep well creep into.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
