ABSTRACT
The article considers the types of stray currents affecting oil and gas pipelines, stages of localization of sources of stray currents and assessment of their danger from the point of view of the development of corrosion damage. To study the characteristics of sources of stray currents, there were carry out synchronous measurements of the current intensity with a contactless method and a pipe-ground potential to determine the coefficient of linear correlation between received data. The result of the study is the justification of the need of elaboration criteria for identifying sources of geomagneticinduced currents.
KEYWORDS: telluric currents, geomagnetically induced currents (GIC), protection of pipelines against corrosion, criteria for GIC hazard assessment.

ABSTRACT
The article analyzes the most dangerous case of loss of stabilization of the situation, consisting in the possible blurring of the soil backfill during the exploitation of the pipeline. Scientists who developed analytical dependencies to find the longitudinal critical force and ensure the stabilization of the design position of the pipelines are presented, considering various cases of their laying. It is proposed to quantitatively investigate the effect of possible erosion of the soil on the overall stability in the longitudinal direction of the underwater pipelines in the form of an analytical dependence. According to the results of the research, an analytical dependence is obtained between the longitudinal critical compressive force and the probable length of the washed out section of the underwater pipeline, the use of which in the design will reduce or prevent the loss of stabilization of the design position of the underwater pipelines as a result of possible erosion of the
soil backfill during operation by applying additional measures for ensuring stability in advance.
KEYWORDS: underwater pipeline, blurred section, stabilization of the situation, analytic dependence, longitudinal force, buckling stability.

ABSTRACT
Large reserves of increase of reliability of oil-field pipeline systems, reducing the consumption of steel pipes and reduce energy and labor costs in relaying pipelines is the use of plastic pipes. The limiting factor in the widespread application of corrosion-proof polyethylene pipes in the oil fields is their relatively low bearing capacity (working pressure of the transported medium does not exceed 1.0 MPa). To expand the applications of PE pipes at higher pressures combined pipes are developed and applied at oil and gas fields with a working pressure up to 4.0 MPa. Such tubes are polymer reinforced pipes PRP. It was developed a three-dimensional nonlinear model of the mechanical behaviour of reinforced polymer pipes taking into account the structure parameters, contact interaction, nonlinear deformation of components. The model allows to investigate stress-strain state of the PRP under various conditions of loading. It was performed the study on the influence of structural parameters of the PRP on the bearing capacity of the pipeline. The calculation of the stresses was made occurring in the PRP of various diameters under various conditions of loading.
KEYWORDS: model, mathematical modeling, pipeline, corrosion, polymer reinforced pipeline, strength.

ABSTRACT
The article presents the results of a studying dangerous hydrogeological factors, which effects on operational safety, reliability and efficiency of oil and gas pipelines. The classification of ways and methods for estimating the stress-strain
state of pipelines allows us to distinguish two groups of methods: measurement of the spatial position and calculation of stresses and direct measurement of stresses in the pipes. There are presented the advantages and disadvantages of considered methods. As a result of the study, the authors substantiated the need to implement measures to monitor longitudinal stresses in the walls of oil and gas pipelines using fiber-optic sensors.
KEYWORDS: oil and gas pipelines, reliability, efficiency, monitoring, stress-strain state, complicated conditions.

ABSTRACT
In this paper were developed some recommendations to optimize methanol consumption. The scope of the research was a CGTU with a production capacity of 1.5 billion Nm3 per year. In present paper, the operational regime was assumed
at inlet pressure of 3.2 to 5.2 MPa and the composition of the gas was considered according to the production data in 2017. The aim of the work was optimization of methanol consumption during the inhibition of technological gas pipelines and identification of characteristic trends of optimal methanol consumption depending on the pressure of operation of the CGTU. To reduce methanol consumption there were applied a set of measures and film apparatus, which also improve the quality of natural gas treatment and extend the period of operation of the field at the stage of falling production without input compressor. Location of a feed point depends on gas treatment conditions. Developed technology allows significant flexibility in operation regimes depending on requirements to quality of the commercial products. It might be consider as a component of a complex solution in efficiency improve of gas field production. Developed recommendations are applicable during the processing of well streams from gas and gas condensate fields when using proposed technological scheme. The main technical solutions protected by licenses of Russian Federation.
KEYWORDS: methanol, technological gas pipeline, refluxer, central gas gacility, low-temperature separation.

ABSTRACT
Analysis of the results of the survey of main gas pipelines by means of in-line flaw detection, capable of measuring the actual bend radii, showed that the earth blocks in the geodynamic zones move in the plane of the bend, entraining the pipeline, with the appearance of non-normative bending radii. It is shown that the places of the greatest concentration of accidents (about 90%) fall on the zones of influence of active geodynamic zones. As criteria for the non-normative bending radii 500D or more are accepted, at which the K60 tube steel retains its elastic properties, i.e. bending stresses higher than the normative ones are unlikely at bending radii of 250D or less, at which the flexural stresses are close to the yield strength of the pipe steel, which in accordance with the standards is unacceptable. It has been established that at the intersections with the geodynamic zones processes occur that affect the radius of the bending of the pipeline and, accordingly, its stress-strain state, for example, the number of sections with bend radii less than 500D has increased from 80 (33 years) to 128 (35 years), i.e. 60%.
KEYWORDS: main gas pipeline, technical condition, radius of bending, geodynamic zones, in-tube defectoscopy.

ABSTRACT
Analysis of the derivate of reflectivity spectrum in the red transition zone allows determine the health condition and contamination of plants. Currently known methods of determining the degree of contamination of soil with hydrocarbons
using derivative of spectroscopy prove the great potential of the derived methods in the spectral analysis of flora. Derivative spectroscopy applied to the area of the red transition allows evaluate not only the total above-ground biomass of plants but
the degree of contamination of soil by hydrocarbons. There is an important role of derivative spectroscopy to determine the degree of soil contamination by hydrocarbons in the study of reflective spectrum of plants in the red transition zone. Analysis of the existing factual material in determining the degree of contamination of soil and health of plants based on the first derivative of spectrum reflectivity in the red zone transition showed a lack of mathematical apparatus, allowing link individual results of known experimental researches. It was proposed a new integrated measure of contamination of soil by hydrocarbons containing a reconciliation function that allows link logically the above-ground biomass of plants, first derivative of the reflectivity spectrum in the red transition zone and the degree of soil contamination.
KEYWORDS: biomass, hydrocarbons, contamination, red transition zone, spectroscopy, pollution.
