During transportation of crude oil and refined products for long distances the above-ground segments of a pipeline, in their passage through such obstacles as mountains, water bodies, communications, etc., get bent by gravity and can execute spatial vibrations under the effect of alternating internal pressure. Pipeline vibrations can be stronger or weaker depending on certain relationships among parameters. Thus, an investigation into pipeline spatial vibrations is of much topicality and practical importance.
Consideration is given to spatial vibrations of a pipeline with liquid contained in it about the horizontal axis that passes through bearings. In a steady state the pipeline is bent by gravity and is affected by internal pressure. The elasticity coefficients of the bearings and deformations of the pipeline associated with its exit out of the bending plane are reckoned as small; therefore the pipeline bent axis represents a planar curve. In this case, one should allow for inertial Coriolis forces, buoyancy force and drag force proportional to the first-order velocity. Based on the obtained model we have developed a set of two nonlinear differential equations for the pipeline flexural and rotational vibrations solved with the aid of the sequentially applied Bubnov-Galerkin and Runge-Kutta methods. Free vibrations of the pipeline have been examined. Computational results for actual values of the key parameters are given in the form of diagrams. General conclusions are presented in the work.

As the result of infrared spectroscopy and qualitative chemical analysis the carbon structure in composition of iron-carbon alloy that determine general service characteristics of constructional steel has been explored. Traditional perceptions of carbon structural condition in composition of carbon-iron alloy are enough dissonant. In view of recent developments on carbon structure and on revelation of fullerenes C60 and C70 in composition of iron-carbon alloy a hypothesis for fullerene substance of carbon in iron matrix has been developed. IK-Fourier spectroscopy showed perfect convergence of spectrum of reference specimens of fullerenes C60 and C70 after fluorhydric acid treatment and spectrum of iron-carbon alloys.

Number of wells which are equipped by sucker rod pump units steadily increasing in most part of Western Siberia oilfields, due to passing to last or final stage of their usage. Accidents, first of all back off and parting of sucker rods and tubing, lead to significant increase of price of extracting oil. The reason of back off is torque which originates in string rods during it’s deformation under action of resistant forces against downward moving of plunger, “Lubinskii effect” and spatial curvature of borehole. As these factors can’t be eliminated during operating process, their action on threaded connection of sucker rods can be minimized by using of hinge joints.
Increasing operability of sucker rods and tubing is possible by decreasing of torque, acting on breakout of threaded connection during operating process. The purpose is to reduce frictional torque in hinge, which is transmitting element of a string, with the help of constructive solutions.
Relevance of back off problem is confirmed by oilfield data analysis. Analytically obtained constructive opportunities of reducing the torque, being transmitted by hinge. Hinge couplings which were made according to analytical investigations allowed to increase overhaul period up to two times.

The estimations of possible and expedient scales of using wind power plants (WPP) in Russia for the liquid gas production are given in the paper. The results are based on three points. The first is the required increase of energy efficiency and equipment of Russian oil-gas industry in connection with the realization of its program’s development. The second is the standards of energy equipment of liquid natural gas production, and the third is the revealed wind resources and technical-economical potential for the energy supply in many regions of Russia. According to the calculated results the total capacity and annual electricity production of WPP, economically expedient for the use in liquid gas production in Russia, may reach 21 GW and 70 billion kWh.
