Due to the gradual reserves decrease of major oil fields located in the Western Siberia and gas fields in the Nadym-Pur-Taz region of Tyumen Region the Energy Strategy of Russia for the period up to 2030 envisages compensation of hydrocarbons production volume decrease at the expense of new fields commissioning in remote areas with more complicated climatic and geological conditions as well as building of the appropriate pipeline infrastructure. To provide stable, trouble-free transportation of energy resources the main pipelines (MT) should be equipped by the effective system of geotechnical monitoring (GTM). The paper presents the basic techniques of implementation and principles of work of the technical solution on integration of automation systems and communication lines oil and gas facilities with one of the modern technologies of conducting geotechnical monitoring (GTM) on the basis of fiber-optic temperature and strain sensors.
Key words: geotechnical monitoring; fiber optical systems; strain sensor; temperature sensor; main pipeline.

Azerbaijan State Oil Academy 20, Azadlyg prosp., AZ1010, Baku, Republic of Azerbaijan, tel.: +(99450)-372-46-52, e-mail: leyla_372@yahoo.com.
The paper studies spectral characteristic, kinetics of In2O3–SiO2–Si–SiO2–Al-structures photo current under various voltage as well analyzes factors that influence sensitivity of metal–dielectric–semiconductor–dielectric–metal structures to impact of electric field and highlight with the aim of creating a photo-receiver with controlled sensitivity. It is revealed that the obtained In2O3–SiO2–Si–SiO2–Al-structure is highly sensitive to electric field and highlight and this fact can serve the basis for creating highly sensitive photo-receiver with controlled electric field.
Key words: electric field; spectral characteristic; voltage; photo sensitivity; potential barrier.

ASSESSMENT OF FUNCTIONING RELIABILITY OF OFFSHORE DRILLING PLATFORMS (p. 30)
Sergei Grigorievich Chernyi, Candidate of technical sciences, Anton Alexandrovich Zhilenkov, Senior lecturer
Kerch State Maritime Technological University 82, Ordzhonikidze str., 298309, Kerch, Crimea, RF, tel./fax: (06561) 3-55-14, e-mail: sergiiblack@gmail.com
The article reviews the existing and planned implementations of electric power systems of offshore drilling platforms. The review served the basis for identification of the typical systems and assessment of their reliability and energy efficiency. With all the advantages of the systems under consideration the researchers, carried out at drilling rigs, that are used for hydrocarbons production on the shelf of the Black Sea basin, revealed the overall negative features in their functioning. The article presents the results of diagnostic studies of offshore platforms with the system of the direct current main drive, supplied from a variable current station through the electric power static converters. On the basis of the performed measurements the electrical engineering complex under study can be described as follows: the presence of current harmonics and voltage, the values of which are significantly higher than the allowable ones, causing a variety of negative consequences for marine electrical equipment up to thyristor converter breakdown; high value of crest-factor of current and voltage; activation of functional protection under loads not exceeding the nominal ones; load of power generators by inactive capacity. These data was used to estimate the impact of the above-mentioned negative factors on the reliability of the basic elements of the autonomous power system and to give recommendations on its improvement.
Key words: drilling rig; system reliability; automatic control and regulation systems; harmonic distortions; functional protection; electrical equipment; reliability factor.

Systematic analysis of the modern state of heat transfer processes in horizontal pipelines and oil wellbores has been carried out. Disadvantages of the existing works while mathematical modeling of heat transfer process from ascending fluid flow to the rock have been shown. Considering geothermal gradient and heat conductivity of liquid and gas in inter-pipe space, that is between the tubing and the casing string, a new adequate mathematical model of heat transfer process has been offered.
Key words: heat transfer; heat conductivity, rock, temperature, fluid flow, geothermal gradient.
