Разработка программных средств прозрачного удаленного доступа к технологическим параметрам бурения и данным скважинной телеметрической системы в условиях нестабильной связи

Abstract

In some cases, the drilling of oil and gas wells requires support for the drilling process, which consists in monitoring the parameters and making urgent decisions. Accompanying drilling takes place using the existing communication channels between the office and drilling. Satellite and mobile communications are most common. They are characterized by a low speed of receiving and transmitting data, frequent disconnects, the use of NAT. As part of this work, a software tool has been developed for transparent access to drilling parameters and measurements while drilling from a telemetry system in order to organize remote tracking via existing communication channels, taking their limitations into account. The software was based on the implementation of the SSH protocol, which provided compression and encryption of the transmitted data and transparent access to TCP services at the rig. This makes it possible to use existing software to access drilling measurements, which makes it possible to reduce the amount of data transferred in comparison with remote desktops. The software has been tested in conditions close to the field, and has shown its suitability for solving the tasks it was designed for.
