Abstract
The utility model relates to an oil drill with Tee joint which is machined by adopting blank forge pieces. The oil drill with tee joint is provided with three connectors which are a first connector, a second connector and a third connector. The central axis of the second connector is perpendicular to the central axis of the first connector and the third connector. The distance between the first connector and the central axis of the second connector is 350mm -400mm. The distance between the third connector and the central axis of the second connector is 170mm - 400mm. The distance between the first connector and the third connector is in a range of 520mm -800mm. The wall of the connector comprises a common layer and a thickening layer. The thickness of the common layer is in a range of 10mm - 40mm. The thickness of the thickening layer is in a range of 20mm - 50mm. The oil drill with tee joint has the advantages of being reasonable in structure design, strong in durability, high in strength and good in quality.
Description
Technical field
The utility model relates generally to a kind of petroleum drilling and mining tee union, is used for oil well platform drilling-production equipment mud, cement, the connection of production test pipeline.
Background technique
At present, the existing mud that is used for petroleum drilling and mining platform drilling-production equipment, cement, the tee union that the production test pipeline connects, because operating environmental condition is abominable, the corrosivity of conveying medium is so that existing tee union, resistance to compression is low, poor durability, long-term abominable H
2Use under the S environmental conditions and need to tie up frequently the family maintenance, cost of production is high.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of reasonable in design, corrosion resistance are strong, a kind of tee union of long service life.
The utility model solves the problems of the technologies described above the scheme that adopts: this a kind of petroleum drilling and mining adopts the blank forged piece machining to form with tee union, described a kind of petroleum drilling and mining is provided with 3 interfaces with tee union and is respectively first interface, the second interface and the 3rd interface, the second interface medial axis and first interface, the 3rd interface medial axis is perpendicular, first interface to the second interface medial axis distance is 350mm-400mm, the 3rd is interfaced to the second interface medial axis distance is 170mm-400mm, described interface wall thickness is divided into two-layer common layer and thickening layer, the distance range of described first interface to the three interfaces is 520mm to 800mm, described common layer and thickening layer, common layer wall thickness range is 10mm-40mm, and the thickening layer wall thickness range is 20mm-50mm.
A kind of petroleum drilling and mining described in the utility model is the ANSI4130 material with the tee union main body.
The utility model is compared with prior art and had the following advantages and effect: the utility model new structure is reasonable in design, the employing trade mark is that the ANSI4130 material is as the forging material, tensile strength 〉=100000PSI, yield strength 〉=80000PSI, the utility model can be long-term normal use the under the environment of oil at fed sheet of a media, durability is strong, but cracking resistance under the sulfide hydrogen environment, intensity is high, and quality is good.
