Description
Technical field
The present invention relates to petroleum casing pipe field, in particular to a kind of processing technology of steel level oil bushing.
Background technique
Petroleum casing pipe is the steel pipe for being used to support oil, the gas well borehole wall, to guarantee that drilling process carries out and oil entire after complete well
The normal operation of well.Every mouth well will use several layers of casings according to different drilling depth and geological condition.Casing is wanted after going into the well
Using well cementing of cement, it is different from oil pipe, drilling rod, it is not possible to reuse, belong to disposable consumable material.So casing
Consumption accounts for 70% or more of whole oil well pipes；
Petroleum casing pipe is a kind of tube product that petroleum industry is widely used, standard oil casing grade mechanical performance index
It is required that stringenter, yield strength range is very narrow, and difficulty is very big for existing quenching, tempering furnace situation.When production
The fluctuation of steel pipe yield strength is larger, and the product mechanical property after processing is bad, cannot fully meet standard requirements, one when processing
Secondary inspection qualification rate is less than 60%.The processing technology of steel pipe is promoted, release production capacity becomes the task of top priority；For this purpose, it is proposed that one
The processing technology of kind steel level oil bushing.
Summary of the invention
The main purpose of the present invention is to provide a kind of processing technologys of steel level oil bushing, can effectively solve background skill
The problems in art.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of processing technology of steel level oil bushing, the procedure of processing of the petroleum casing pipe are as follows:
(1), melt is made steel in electric furnace, and pipe is made in vacuum gas filling；
(2), it is perforated to pipe, tube rolling, sizing, and the press quenching in quenching press；
(3), it is sufficiently tempered and keeps the temperature after quenching, obtain petroleum casing pipe；
(4), it is machined after being cooled and shaped.
Preferably, tempering insulation time is 127-160 minutes in the step (3).
Preferably, in the step (2) when quenching steel pipe tail portion, temperature is 790 DEG C -800 DEG C.
Preferably, irrigation pressure is 1.5kg-4.0kg in quenching press in the step (2).
Preferably, the support wheel rotation speed in the step (2) in quenching press is 75r/min-95r/min.
Preferably, adjustment again all is carried out to whole burners of electric furnace before each step (1) production.
Preferably, it is utilized after the step (1) during stop production to overhaul and clears up gas piping, calibrated meter precision.
Preferably, the finished product length of step (4) machining is less than 11.5 meters.
Preferably, the melt in the step (1) in electric furnace is steel scrap.
Preferably, irrigation pressure is 1.5kg-3.0kg in quenching press in the step (2).
Compared with prior art, the invention has the following beneficial effects:
(1) the step 1 tempering heating and thermal insulation time is 160 minutes, can guarantee abundant tempering of the steel pipe in furnace, it is ensured that tissue
Transformation it is abundant；
(2) step 2 is when quenching steel pipe tail portion, because harden ability is there are difference end to end, entire lowering when producing steel pipe tail portion
To 790 DEG C, to guarantee that performance is substantially close end to end；Irrigation pressure is forced into 3.0kg in quenching press in step 2, can reduce
Performance difference end to end；Support wheel rotation speed in step 2 in quenching press is 95r/min, and steel pipe can be made circumferentially to organize more
Uniformly；
The present invention improves product quality, and petroleum casing pipe mechanical property adjusted significantly improves, and qualification rate significantly mentions
It rises, improves economic benefit, using effect is more preferable relative to traditional approach.
Detailed description of the invention
Fig. 1 is a kind of overall structure flow chart of the processing technology of steel level oil bushing of the present invention.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Tempering insulation time is 127 minutes in step (1) in original processing technology, in hardened steel in step (2)
Temperature is 800 DEG C when pipe tail portion, and irrigation pressure is 1.5kg in quenching press in step (2), quenching press support wheel rotation in step (2)
Rotary speed is 75r/min,
Tempering insulation time extended to 160 minutes from 127 minutes in step (1) in processing technology of the invention, guaranteed steel
Abundant tempering in Guan Lu, it is ensured that the transformation of tissue is abundant；In step (2) when quenching steel pipe tail portion, temperature is whole from 800 DEG C
Body declines 10 DEG C to 790 DEG C, because harden ability end to end is there are difference, 10 DEG C of entire lowering of steel pipe tail portion when production, to guarantee head
Tail performance is substantially close；Irrigation pressure from 1.5kg is forced into 3.0kg in quenching press in step (2), and it is poor can to reduce performance end to end
Value；95r/min of the support wheel rotation speed by original 75r/min change till now in step (2) in quenching press, makes steel pipe
Circumferential tissue is more uniform；Adjustment again all has been carried out to tempering furnace whole burner before each step (1) production, has restored burner work
Condition, temperature stability are further strengthened；Using gas piping is cleared up during stop production to overhaul after step (1), calibrate
Accuracy of instrument reduces the pressure oscillation of coal gas supply, strengthens Control for Kiln Temperature precision.
