Embodiment 1

[0032] Embodiment 1: a kind of production technology of parts for fracturing of oil exploitation equipment, comprises the following steps:

[0033] (1) Refining: the mass percentage is Cu: 1%, Mg: 2%, Sn: 0.5%, Zr: 0.1%, Re: 0.05%, Ni: 0.01%, Si: 0.1%, Zn: 0.2%, SiC particles: 5%, rare earth: 0.05%, TiB: 3%, Al 2 o 3 1%, the balance is Fe raw materials for mixing and refining;

[0034] (2) Forging: Raw materials are initially smelted in an electric arc furnace and pretreated for desulfurization, and then blowing and slag removal using converter process dephosphorization technology. After deep desulfurization in LF ladle refining furnace, RH furnace vacuum circulation is used for degassing, and continuous casting of round billets is formed. billet to enhance product strength; high-quality electroslag ingots are used as raw materials, and an 8,000-ton water hydraulic press is used for three-phase forging to ensure uniform composition and compact structure of the forged bille...

Embodiment 2

[0057] Embodiment 2, a production process of parts and components for fracturing of oil extraction equipment, the refining step is: the mass percentage is Cu: 6%, Mg: 3%, Sn: 5%, Zr: 0.5%, Re : 2%, Ni: 0.5%, Si: 0.1%, Zn: 0.2%, SiC particles: 15%, rare earth: 0.2%, TiB: 8%, Al 2 o 3 : 2%, the balance is Fe raw materials for mixing and refining.

[0058] Other method steps in this embodiment are the same as in Embodiment 1.

Embodiment 3

[0059] Embodiment 3, a production process of components for fracturing of oil extraction equipment, the refining step is: the mass percentage is Cu: 3%, Mg: 5%, Sn: 3%, Zr: 0.3%, Re : 5%, Ni: 0.3%, Si: 0.3%, Zn: 0.4%, SiC particles: 10%, rare earth: 0.1%, TiB: 5%, Al 2 o 3 3%, and the balance is Fe for mixing and refining.

[0060] Other method steps in this embodiment are the same as in Embodiment 1.

Abstract

The invention discloses a production process of parts for oil exploitation equipment fracturing. The technical problem that an existing manufacturing method of the parts for oil exploitation equipmentfracturing cannot give consideration to the performance and the yield of the parts is solved. The process comprises the technological steps of refining, forging, heat treatment after forging, machining, forging piece surface sputtering and the like, the refining step adopts a special component proportion, two times of turning upsetting and drawing and three stages of forging and pressing are adopted in the forging process, and it is guaranteed that a forging piece does not crack in the forging and pressing manufacturing process. According to the process, the hardness of the inner surface canbe improved, meanwhile, the strength and the toughness are kept, the anti-scouring and anti-abrasion effects are achieved, the crack phenomenon is not likely to happen under the action of alternatingloads, through forcing piece surface sputtering, the overall strength performance is improved, the service life is prolonged, the production cost is reduced, potential safety hazards in treatment arereduced, the process is simple, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of production of fracturing forgings, in particular to a production process of parts for fracturing of oil exploitation equipment. Background technique [0002] In the field of petroleum, fracturing refers to a method that uses hydraulic action to form cracks in oil and gas layers during the process of oil or gas recovery, also known as hydraulic fracturing. Fracturing is to artificially create fractures in the formation, improve the flow environment of oil underground, increase the production of oil wells, and play an important role in improving the flow conditions at the bottom of oil wells, slowing down interlayers and improving the production status of oil layers. Fracturing construction requires the use of fracturing vehicles to fracturing oil wells. Media such as ceramsite sand and fracturing fluid pass through the pressure end to generate high pressure to crack the bottom layer instantly. At the same ...
