Production material circulation technology of oil casing coupling

Abstract

The invention provides a production material circulation technology of an oil casing coupling, and belongs to the field of oil casing coupling machining production. The process comprises the followingsteps that a wool blank is fed from a rotary stock bin to a feeding position by utilizing a feeding robot; the wool blank is fed into a numerical control machining machine tool for automatic machining by using a material taking truss mechanical arm; and a machined product is grabbed by the truss mechanical arm to a discharging position; the feeding robot is used for conveying the machined productto a material conveying channel; the product sequentially passes through a code printing and a thread inspection procedure in the material conveying channel, and unqualified product which fails in geometric parameters is removed; the product is subjected to magnetic powder inspection; and the finished product subjected to magnetic powder flaw inspection is grabbed into a semi-finished product transfer basket of the rotary stock bin of the discharging position by utilizing a discharging robot; and a discharging forklift is used for conveying the finished product to the rotary stock bin of thedischarging position. The production material circulation technology of the oil casing coupling can solves the problems of high labor intensity, complex working procedures, low automation degree of anexisting coupling production technological process.

Description

technical field [0001] The invention belongs to the technical field of processing and production of oil and casing collars, and more specifically relates to a material circulation process for producing oil and casing collars. Background technique [0002] Oil casing or casing belongs to the necessary equipment in the field of petroleum drilling, cementing and completion engineering. It is a safe, reliable, low-cost, fully functional and widely applicable downhole support and equipment for sealing open hole wellbore. It is used for various sizes of support body, sealing open-hole wellbore, the circulation between the casing or tubing string and the wellbore, and the upper and lower casing or tubing strings, so as to ensure the up and down flow of the fluid in the wellbore. And prevent the inflow of fluid in non-production formations, so as to ensure the smooth progress of construction operations such as layered water injection, acidification, fracturing, self-flow completion,...
