Efficient petroleum screen tube drilling machine and processing technology thereof

Abstract

The invention provides an efficient petroleum screen tube drilling machine. The efficient petroleum screen tube drilling machine comprises a base frame, a drilling mechanism, a conveying mechanism anda clamping mechanism, wherein the drilling mechanism, the conveying mechanism and the clamping mechanism are arranged on the base frame, the drilling mechanism is used for drilling holes of a petroleum screen tube, the conveying mechanism is used for feeding the petroleum screen tube, the clamping mechanism is used for fixing the petroleum screen tube to be machined, the drilling mechanism comprises three motors, and the motors are in transmission connection with eleven drill bits through a gearbox. The invention further provides a processing technology of the efficient petroleum screen tubedrilling machine. The high-efficiency petroleum screen pipe drilling machine has the beneficial effects that the three motors are used for driving the eleven drill bits, so that the mode that one drill bit is driven by a motor is changed, the production cost is reduced, and meanwhile the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of drilling and production equipment, in particular to a high-efficiency oil screen drilling machine and a processing technology. Background technique [0002] In oil drilling and production operations, screen pipe is an important equipment, and it is often used for pre-completion or oil production for sand control. At present, the most used screen is the drilled screen. Due to the superior performance and low price of drilling pipe, it has been highly valued and widely used by major oil fields as soon as it appeared. The emergence of drilling screens provides material conditions for the development of horizontal wells and sidetracking wells and the oil production of high-sand reservoirs. [0003] The advanced and high-efficiency equipment for processing drilled screen pipes is currently mainly imported from abroad, such as Italian laser cutting machines. The advantage is that the cutting specifications ca...

AI Technical Summary

Problems solved by technology

[0003] The advanced and high-efficiency equipment for processing drilled screen pipes is currently mainly imported from abroad, such as Italian laser cutting machines. The advantage is that the cutting specifications can be changed at will only by changing the program, and the processing range is wide. The disadvantage is that the equipment is expensive and requires millions of dollars. The processing efficiency is also low; some manufacturers use standard drilling machines to process screen pipes, because only one drill bit can only process one hole at a time, the processing efficiency is extremely low and the clamping is difficult and the operation time is long, which is not conducive to mass production
