熱軋鉆鋌用無縫鋼管的工藝實(shí)踐

Manufacturing Process Practice of Hot-rolled Seamless Steel Pipe as Stock for Drill Collar

摘要: 石油開采用鉆鋌的使用環(huán)境惡劣,因此對其性能要求高,而采用傳統(tǒng)生產(chǎn)工藝制造鉆鋌用管,加工周期長,成本高。介紹了采用Assel軋管機(jī)組生產(chǎn)鉆鋌用無縫鋼管的工藝開發(fā)過程以及鉆鋌用厚壁管軋制過程的變形量分配,通過工藝參數(shù)優(yōu)化,解決生產(chǎn)中的工藝控制難點(diǎn),實(shí)現(xiàn)穩(wěn)定軋制。

Abstract: Due to the harsh operation conditions of the drill collar in oil exploration,stringent criteria is put forward for performance thereof. The conventional manufacturing process for the drill collar features such disadvantages as rather long processing cycle and low cost efficiency. Elaborated in the article are the manufacture of seamless steel pipes for drill collar stock purpose with Assel pipe mill,covering such aspects as the process R & D,the deformation distribution during the rolling process of the drill collar-purposed heavy-wall pipe and optimization of the process parameters which crashes the hard nuts of process control for the purpose of rolling consistency.
