An automatic milling machine for sand control screen

Abstract

The invention relates to an automatic slot milling machine for a sand control screen pipe. The automatic slot milling machine comprises a control mechanism, a rotary feeding mechanism, a supporting mechanism and a slot milling mechanism, wherein the control mechanism is used for controlling a working state of the whole automatic slot milling machine, including the rotary feeding mechanism and the slot milling mechanism; the rotary feeding mechanism is used for driving the sand control screen pipe to rotate and move towards the slot milling mechanism; the supporting mechanism is used for supporting the sand control screen pipe; the slot milling mechanism is used for milling a slot in the pipe wall of the sand control screen pipe. The automatic slot milling machine for the sand control screen pipe fulfills the aim of automatically milling the slot in the pipe wall of the sand control screen pipe; the production cost and the labor intensity are greatly reduced; the production efficiency is improved; the production demands on low cost and high efficiency of an enterprise are well met; the high technical support is supplied to the enterprise for large-scale and automatic production.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery processing, in particular to an automatic sand control screen pipe milling machine for automatically processing filter assembly installation grooves on the pipe wall of the sand control screen pipe. Background technique [0002] In the process of crude oil extraction in the petroleum industry, mechanical sand control devices are required. The previous mechanical sand control devices generally used slotted screens and wire-wrapped screens. The slotted screen is directly processed on the pipe wall, and the minimum gap width is 0.25mm, which limits the sand control of powder and fine sand, and its flow area is small, so it cannot achieve the self-cleaning function, and often has clogging during the filtration process. phenomenon, the size of the gap is easily enlarged due to corrosion, and the effective period of sand control is short; although the wire-wrapped screen increases the flow a...

Problems solved by technology

In the process of making the sand control screen described in the above patent, it is necessary to process the installation groove of the filter assembly on the pipe wall of the sand control screen. At present, the processing of the installation groove is usually done manually, and the labor cost is high and the production efficiency is high. Low, and the weight of the sand control screen is heavy. In the process of manual processing, the sand control screen needs to be rotated to process the installation grooves around the sand control screen. It is very time-consuming and laborious, and cannot meet the low-cost and high-efficiency production needs of enterprises. , and does not meet the development needs of large-scale and automated production of enterprises
