The aim of this work is to study the synchronization system in wireless sensor networks of remote objects of the oil and gas complex. The objective of the study is to ensure the timely collection of reliable information about the parameters of the process. In the course of the study, methods of theoretical circuitry and mathematical modeling were used, in particular, regression and analytical models, methods of probability theory and mathematical statistics using MathCad and Matlab software packages. The conducted studies indicate a high vulnerability of the radio links of the infocommunication system for monitoring the parameters of remote objects of the oil and gas complex from attacks on the synchronization system when using deterministic synchronization signals in it. The results achieved allow us to provide the specified requirements for reliability and timeliness when deploying modern wireless sensor networks in the oil and gas industry.

Abstract In the oil and gas industry, manufacturers are continuously engaged in providing machines with improved performance, reliability and availability. First Stage Bucket is one of the most critical gas turbine components, bearing the brunt of very severe operating conditions in terms of high temperature and stresses; aeromechanic behavior is a key characteristic to be checked, to assure the absence of resonances that can lead to damage. Aim of this paper is to introduce a method for aeromechanical verification applied to the new First Stage Bucket for heavy duty MS5002 gas turbine with integrated cover plates. This target is achieved through a significantly cheaper and streamlined test (a rotating test bench facility, formally Wheel Box Test) in place of a full engine test. Scope of Wheel Box Test is the aeromechanical characterization for both Baseline and New bucket, in addition to the validation of the analytical models developed. Wheel Box Test is focused on the acquisition and visualization of dynamic data, simulating different forcing frequencies, and the measurement of natural frequencies, compared with the expected results. Moreover, a Finite Elements Model (FEM) tuning for frequency prediction is performed. Finally, the characterization of different types of dampers in terms of impact on frequencies and damping effect is carried out. Therefore, in line with response assessment and damping levels estimation, the most suitable damper is selected. The proposed approach could be extended for other machine models and for mechanical audits.

Oil And Gas Production

At present, repair and diagnostic complexes are being developed for repair of oil and gas production facilities, including control areas for working capacity, diagnosing components used in maintenance stations, as well as areas equipped with the necessary technological equipment, measuring instruments, tools and equipment for carrying out current repair of replacement elements. For maintenance of repair, repair-diagnostic complexes are equipped with means of power supply, sets of spare property and accessories and operational documentation. Repair-diagnostic complexes can be represented using a three-phase multi-channel queuing system. The study of such a system with the distribution functions of the service time of applications different from the exponential makes it difficult to use analytical models. The developed simulation model of the repair and diagnostic complex allows to evaluate the characteristics of its functioning, the most important of which is the average service time of the application in the system, as well as to determine the required number of channels on each site. The developed model can be aggregated into a general model of research into the operation of complex technical systems for supplying oilfield facilities.
