In the article the author considers the stages of development of strategic planning approaches and tools, analyzes the shortcomings of each approach, and creates conditions under which it is expedient to use various strategic planning tools. The main stages of the evolution of scientific schools of strategic planning are systematized: school of design, planning, positioning, entrepreneurship, cognitive school, teaching, power, culture, environment, and configuration.
Presented are modern approaches to strategic planning, widely applied in practice by domestic and foreign companies. The practice of using modern approaches to strategic development planning by oilfield service companies has been studied, and a number of differences between Russian and foreign companies have been revealed. Strategic planning for the development of foreign companies is of a long-term nature. In spite of the fact that there is a well-defined plan, in fact planning is very flexible and with the slightest change in the market, corrections are immediately made to the created plan and are adjusted to the current situation. A great deal of attention is paid to the problems of increasing the productivity of production, as well as to increasing the cost of business.
Studying the experience of strategic planning of Russian oilfield service companies shows that they actively use such strategic directions as integration, diversification, access to new markets. Based on the study, the main problems of strategic planning for the development of Russian oilfield services companies were identified. Domestic companies have difficulties in conducting analysis and forecasting of economic processes within the company, determining their strategic position in the market, developing and evaluating alternative development options. The need to improve the methodological support of strategic planning for the development of oilfield service companies, taking into account industry specifics, is determined.
Rational Software main transport natural gas in a reduction of gas mains load is accompanied by the increasing complexity of technology and the improvement of traffic management systems gas. An important role is given to the development of the system of dispatching management, one of the areas which is to implement the results of research evidence of system performance based on advanced mathematical models and technologies. Applied Information Systems are increasingly used in the problems of effective use of the equipment in the main gas transport.
Priority scientific and technical challenge of PJSC «Gazprom» is to improve the technology of gas trunk line.
In this regard, one of the most promising areas of research is the creation of mathematical models and methods of forecasting the volume of pumping natural gas through main pipelines for solving rationing problems and dispatching management planning. Developed earlier prediction technology focused mainly on the stationary conditions and the use of specific norms of consumption of natural gas for its own needs of compressor stations. Modern conditions of functioning of the gas transmission system characterized by a decrease in pumping volumes of natural gas each year.
In this paper we propose a method that allows to predict the volume of transit of natural gas through MG, taking into account the seasonal, daily and hourly unevenness of gas consumption (harmonic oscillation with random amplitudes and random phases).
To monitor the daily and seasonal hours the dynamics of gas consumption shows the possibility of presenting the dynamics of the volume of pumping natural gas through pipelines on the basis of time-series visualization in the form of fractal surfaces, which allows you to select components of the random time series.
Efficient natural gas trunkline transportation in conditions of gas trunklines load reduction accompany increasing complexity of technology and natural gas traffic management systems improvement. An important role is given to development dispatching management systems one of which trends is implementing practical research of equipment results based on advanced mathematic models and technologies. Increase applied information systems use for solving problems of gas trunkline equipment effective operation.
Priority sci-tech challenge of PJSC «Gazprom» is improving technologies of gas trunkline transportation.
In this regard, one of the most promising areas of research is mathematic models and forecasting volume of pumping natural gas through main pipelines methods development for solving rationing problems and dispatching management planning. Earlier prediction technology focus mainly on the stationary conditions and use specific natural gas consumption norms for technological needs of compressor stations. Modern conditions of gas transmission system functioning characterize by decreasing pumping volumes of natural gas each year.
Decreasing pumping volumes and increasing inequality of gas supply may cause increasing gas consumption for pumping needs and reducing economic indicators due to changing operation parameters of compressor stations.
The paper evaluate the type of data distribution in terms of pumping gas through three thread corridor gas trunklines through which 1/5 of the total natural gas produced in the Russian Federation is pumped. Recommendations on estimates natural gas pumping volumes in case of declining load of main gas pipelines obtained.
This article describes the types of corrosion and the patterns of their use of inhibitors, depending on the operating conditions of the pipeline.
One of types of anticorrosive actions is the inhibitory protection of an internal surface of pipelines based on use of chemical reagents — corrosion inhibitors. Conducting chemical inhibitory protection is one of the most effective, technologically available and at the same time economically reasonable methods of fight against internal corrosion of field pipelines.
In article it is shown that certain requirements are imposed to inhibitors of corrosion: this ensuring required protective action both in the conditions of high pressures and temperatures, and in case of usual conditions — temperature of +40 °C and normal atmospheric pressure, and in the conditions of high speeds of a flow and availability in it abrasive particles, and also inhibitor shall have the low temperature of hardening (at least – 50 °C), good solubility in the corrosion environment and a high adsorptive capability, inhibitor shall not influence stabilization of water oil emulsions.
Therefore it is necessary to select carefully inhibitors for specific conditions of operation.
However the used reagents not always provide rather high protective effect. It is connected with solubility (dispersancy) of inhibitor in formation fluids, low degree of its compatibility with reservoir waters, the wrong matching of reagent for specific conditions. Usually in practice this problem is solved increase in a dosage of reagent, but such method not always gives the necessary effect. Therefore, creation of new inhibitory compositions which could provide high protective effect in broad range of conditions of application or improvement of quality of already existing structures is necessary.
Examples of tests of corrosion inhibitors, described the process and conditions for their implementation. The evaluation of the effectiveness of corrosion inhibitors, and conclusions are drawn about the possibility of their use.
This article the first time presented the energy and resource saving, import substitution, environmentally friendly nanotechnology surface hardening rapidly wearing parts, which allows the hardening of large parts of ordinary steels on an industrial scale to obtain the structures of nanoscale range. The technology has been checked and implemented in various industries under extreme wear: on bandages shunting and mining locomotives, trams, wheels lifting machines, on the details of cable-suspended road rollers soil mixers brick factories, drums and rollers winches for lifting vessels on fingers joints scoop chain dredges, grabs, on rollers and friction undercarriage tracked vehicles, brake drums and others.
Not limited and often groundless use for the manufacture of these components found environmentally dangerous steel 110G13 containing 15% manganese. Their example shows the huge material damage to nature and society, associated with environmental problems and technological progress.
As a result, poisoning of the environment the second century comes a myriad of toxic substances, most of which can be eliminated.
The age-old problem and not solvable overnight. But that allows even to a small extent to preserve nature and the planet’s resources for future generations should be subject to public scrutiny.
