Optimizing the applied systems of technical maintenance and repair of the equipment is of current concern for many companies. It involves switching to condition based maintenance, which is possible, if methods, means, and depth of the equipment diagnostic are determined clearly. The suggested monitoring system for the mean-square value of vibration velocity based on the s pecified rates of vibration for rotary equipment is an initi al phase of implementing the condition based maintenance, though it is sufficient.


Non-contact system for measuring the thickness of paraffi deposits in downhole equipment and oil pipelines

Alexandra V. Kopteva, Vladimir Yu. Koptev

The article describes the problem of low efficiency of existing techniques for locating and measuring the thickness of paraffin, gums and salts deposits on the inner surface of the pipeline and submersible equipment that have been colloidally dissolved in the transported oil stream. A method based on radioisotope radiation with high efficiency, reliability, durability, ease of maintenance and easy interchangeability of the main components of the system is proposed for the control of deposits. The method allows to detect and measure the thickness of deposits in a non-contact way in a real time mode in a timely manner in order to make a further decision on choosing the most effective technique for their elimination.

Water-cut log of natural gas - new capabilities. Russian laser hygrometer

Valeriy N. Boykov, Oleg B. Vyskubenko, Vladimir M. Karuk, Ivan V. Morozov

The article describes the problem of humidity logging, using existing types of hygrometers, if there are inclusions in natural gas. As it was noted, there are no ways of solution, concerning with inclusions, that form regular solutions, including methanol.The founded alternative - is the laser hygrometer GL-02, which is based on the laser spectroscopy. GL-02 logs thehumidity by extinction of light at a certain wave length, corresponding to one of the lines of water molecules absorption spectrum. According to the principleof its operation process, the device is considered to be the standard of humidity content. The quantity of water molecules - is the primary measurable quantity in gas volume. GL-02 can solve the main problem of natural gas water-cut log - the effect of inclusions, including methanol and glycols. The device registers only water.

Monitoring of technological processes in petrochemical plants

Mikhail Miroshkin

Accurate temperature measurement is an important challenge for the specialists in enterprises around the world. Typically, temperature sensors are used to measure and control the temperature at the local point of process. But in modern enterprises, especially in the petrochemical industry for accurate process monitoring there is a problem of temperature control and read out from multiple reference points at the same time.

About paradoxes of electromagnetic flowmeters

Alexandr Yu. Oshchepkov, Konstantin S. Turuntsev

Electromagnetic flowmeters with a transverse magnetic field and into contact with the medium (EMF) are simple in design, reliable, and relatively no expensive, they are widely used in modern industry, including the oil industry. Analytical solution of the magnetohydrodynamic equations and computer simulation allow a deeper understanding of the physicalprinciples of working EMF and to assess the role of factors influencing the accuracy of measurements.

Development and application of measuring complex to account for viscous oil

Ravil N. Akhmadiev, Azat F. Shigapov, Rafis R. Kazihanov

In 2005 JSC "Tatneft" program was adopted to develop the reserves of heavy oil and natural bitumen. This was due to the fact that the oil fields of Tatarstan are at alate stage of development. This stage is characterized by a gradual deteriorationin the quality of oil, trudnoizvlekaemostyu remaining reserves. Most newly commis-sioned fields have complex geological structure, they occur in low permeability reservoirs.
