At present, scientific and technical innovations are one of the main factors that determine the economic growth and successful development of Surgutneftegas OJSC. Widely exploited in many spheres of activity of oil companies, laser devices can significantly improve the efficiency of technical systems. Volumes of the use of laser technique at the modernization of equipment and technology in Surgutneftegas OJSC are increasing every year, in particular, in the marking of equipment, in the hardening of the threaded surface of drill pipes, high-precision welding et al.

At the end of 2015, the next step in the development of the use of laser technology was the manufacture and installation of laser devices for measuring the length of pipes in existing technological lines for the repair of tubing of the Oil and Gas Production Department Fedorovskneft. The devices are designed to exclude the influence of mechanical factors on the accuracy of the measurement in order to improve the system of preparation and repair of tubing.

The device is a complex of three components: a manipulator, a support and a drop-jet marker. The manipulator provides one degree of freedom: vertical movement on the rack, on the bracket of which the laser range finder is installed. The support is designed to stop the pipe strictly at a certain point at a fixed distance from the laser source of optical radiation, which is provided by a system of inductive and optical sensors.

Analysis of the results of pilot testing of laser devices has shown that applying a measured value of length to the pipe surface allows to optimize the measurement of the total length of the tubing suspension during tripping operations. After the successful testing of laser devices for measuring the length of the pipes of Surgutneftegas OJSC a decision was made to implement this equipment at all specialized pipe repair bases in the oil and gas production departments of the company.
