Problem of defining leakage at multi line gas-main pipeline by standard linear telemetering gear

Sergey V. Yevseyev

The present work objective is to define the main reasons causing complexity of defining leakage location at a multi-line gas-pipeline by a shift dispatching personnel on the basis of the information received from the linear telemechanics system. Analysis of dispatcher actions in case of real breakdown elimination when the gas-pipeline is broken completely was carried out. As a result of the analysis there are indicated available telemechanics systems basic shortcomings and the ways to solve the said problems. An important aspect presented in the work is the necessity of using system approach to the information recorded by the linear telemechanics system and creating additional methods and algorithms for automated processing this information in order to define the time and location of the emerged leakage without specialized sensors.

The use of mobile wireless measuring system for registration the sloughing of sand from gas production wells

Alexey V. Kolmakov, Valeriy P. Ustinov, Sergey S. Savastyuk, Vladimir M. Karuk, Ivan V. Morozov

This publication describes the relevance of creating a mobile telemetry complex on the basis of wireless technologies to ensure the operational control ofthe gas production. In article was paid special attention to risks associated with sloughing of sand from thegas production wells. A practical implementation of a mobile monitoring complex "Parus" of domestic production was presented. This complex solves the problem of registration the sloughing of sand from gas production wells in real time. It were described the complexs construction and its structure. It were described the hardware of building two-level information system, shown the various options for its implementation, allowing to carry out telemetry at different structures hardware of complex, including in its structure of acoustic emission sand registration system. In this article was described registration method of sand in gas stream, which has a difference from analogues as is isolation the sensitivity zone.

A formal approach to the definition of the optimum telemetry aperture value

Alexey G. Zebzeev

Usually the infrastructure of oil producing companies is distributed geographically and has distant objects. Data transmittion from all objects to control point can bring to problems related to the lack of system performance. This paper considersthe issue of the regime of sporadic transmission. It is proposed to use the optimization techniques to dynamically determine the basic characteristicsof sporadic transmission - apertures telemetry to eliminate high congestion of communication channels and ensure normal operation.
