In recent years, with the development of the oil and gas industry, the drilling of highly deviated wells, horizontal wells,
The number of developments is increasing. Laser cutting of petroleum sieves is one of the typical applications of laser cutting technology in the petrochemical industry.
During oil drilling, sand control in loose formations is one of the most critical parts in the design of well completion and production engineering. Generally, a large number of small gaps are processed around the pipe to block most of the sand layer, and laser cutting can cut gradient-type slits with wide widths, narrow widths, and narrow widths, which makes petroleum sieve pipes have better performance.
The laser cutting process of the sieve tube is a process that uses the high energy and high density characteristics of the laser to irradiate the surface of the sieve tube with a laser so that the surface material of the sieve tube undergoes a chemical reaction that causes vaporization or color change.
The processing of the sieve tube using laser cutting method is non-contact processing. Not only does the tool wear, the surface of the sieve tube does not cause any damage, and it can also ensure the cutting accuracy. In addition, laser cutting of the sieve tube can usually increase the degree of automation of the process and greatly improve the processing efficiency. It usually takes only a few seconds to process a seam, which is dozens of times the efficiency of machining.
The main features of laser cutting are:
● Gradient slits can be cut out with wide width, narrow width, or narrow width, making the oil sieve pipe better
● The laser beam is easy to guide, focus, realize direction change, easy to realize automatic processing, and obtain better processing accuracy.
● Laser cutting efficiency is high, usually only a few seconds to process a seam, which is dozens of times the machining efficiency;
● Robots can be used for laser processing in harsh environments or places that are difficult for others to access.
