Gravity Acceleration

The results of repeated measurements of the acceleration of gravity by the Russian absolute ballistic field gravimeter GABL-M on points of oil and gas deposits in the permafrost over a five year period are presented. The changes of gravity acceleration by the absolute gravimeter and GRACE satellite were compared. The results of comparisons of differences gravity acceleration by ballistic gravimeter GABL-M and relative Canadian gravimeters CG5 were [i]shown. The errors in determination of parameters of the gravitational field ballistic gravimeter GABL-M and CG5 gravimeters group were presented. The method of measurement with the gravimeter GABL-M and the method of determining the vertical gradients relative CG5 gravity meters was described. The necessity of introducing corrections of hydrogeology is caused by influence of hydro geological factors on the gravitational field in the permafrost. They are comparable with the values of the field change in the result of gas pumping.

Since reducing energy consumption is a priority for an enterprise, economic effi ciency in general is directly related to the use of pumping equipment. The demand for electricity for pumping equipment will depend on various factors: the operating modes of pumping stations and installations, the equipment used measures to reduce the cost of electricity consumed, etc. The current practice indicates extremely inefficient operation of pumping equipment. Currently, a large number of pumping stations of water supply and sanitation systems operate in an uneconomical mode. Very often, this is due to incorrect selection of pumping equipment, outdated pumping equipment, the operation of pumps in non- calculation mode. In addition, pumping equipment has been installed in many industries since the establishment of production. Such equipment is morally and technically outdated. Now,technological progress allows us to use more efficient equipment and materials that allow us to reduce energy consumption. The article presents an analysis of the energy consumption of a pumping station of technical water supply on the example of JSC «Omsk Kauchuk», a variant of modernization is proposed in order to reduce the consumption of electricity by pumping equipment. The need to modernize the pumping station of technical water supply is associated with a significant service life and high –energy consumption of pumping equipment. Two pump brands were selected and a comparative analysis was carried out. Based on calculations of energy consumption and technological characteristics, the most profitable and optimal version of the D6300-80-2b pump was chosen, since the pump performance is greater and the power consumption is less than that of the JETEX DS600-750 pump, as well as reducing the wear rate of operating elements, improving the pump’s suction capacity

Gas Pumping

Due to enormous material losses in the case of emergency, it is vital to ensure the operation reliability of the natural gas pipeline compressor stations (CS). The risk of breakdown is rather high for gas turbines (GT) with total operation time approaching the design-estimated life and particularly for those in which the actual period of operation exceeds this value. Over 25% of turbine drives working on natural gas transportation net in Russia have exceeded their design life [1]. For instance, around 600 gas turbines of the GTC-10-4 type (10MW power) are still in service despite their 120,000–160,000 hours of operation (more than 1,000 gas turbines GTC-10 type have been made and installed at natural gas pumping stations in the seventies in Russia). These gas turbines contain several critical components. Most of them are related to the high temperature parts, including inner high-temperature turbine casing (ITC). This ITC is a kind of a collector (duct) connecting a combustion chamber outlet and the turbine’s entry. Combined with an insulation layer, it serves as a protective shield for outer (main) turbine casing against the effect of hot gases. Notwithstanding the fact that the GTC-10-4 turbine has a modest inlet gas temperature (TIT∼800°C), there are various problems with the ITC shape and state during the turbine’s operation. The ITC operates under conditions of dramatic temperature changes, pressure drops, extended periods of high temperature. All these factors can cause the ITC shell deformations, which results in poor turbine performances. Regular maintenance inspections including opening a turbine do not permit to establish reasons for dramatic changes in the ITC shape. A detailed numerical analysis has been performed to better understand the ITC dynamics over its service period of operation. Moreover, it should be observed that ITC forms a flow prior to entering a turbine. Then, gas flow is directed to the first stage nozzles of the turbine. Advanced numerical flow investigation methods were applied to improve hot gas distribution in front of the turbine. A considerable decrease in velocity nonuniformity was achieved both radially and circumferentially through the ITC shape optimization. Great need in this component stimulated introduction of a new manufacturing technology aimed at production of new ITCs and replacement of numerous defective ones still used at natural gas pumping stations across Russia. Results of thermo-deformation analysis and numerical flow investigation for various ITC configurations are presented in the paper. It also contains proposals for improving the state of the ITC and outer turbine casing (OTC) in the result of the fixing unit development and applying a new insulation material.

This paper deals with a mathematical problem statement of unsteady fluid flow in heterogeneous porous media with various hydrogeological characteristics. In order to solve the problem the authors developed an approximate analytical method. The method allows multidimensional differential equation in partial derivatives describing the process of fluid filtration in layered porous media to become one-dimensional differential equation. There was obtained a calculation formula for determining the process of mass transfer between the layers, depending on the operating modes of production wells and hydrogeological parameters of filtration layers. The model and the algorithm can be used as a mathematical support for the processes of development of oil and gas fields.

This article is devoted to methods analysis and systems for maintaining the forebay operating modes of pumping stations, which the minimum cost of resources is provided. In modern conditions there is a need to implement measures and solutions to improve the operational performance of pumping stations, which would lead to a decrease in the cost of water supplied. Such activities include the development of methods and systems for the management and maintenance of stations operating modes, which provide the minimum cost of resources. Based on observations, the uneven operation of pumping units over time and as a result of imperfect design of advance cells, the design hydraulic indicators of flow and operational parameters of pumping stations deteriorate. The relevance hydraulic research of forebay regimes and water intakes indicated at a number of meetings on pumps quality. With the development of the recommended set of measures, it is possible to save water and energy resources. The purpose of the work was to conduct full-scale testing of forebay on a large pumping stations in operation, to develop a new design of forebay and its hydraulic calculation. During work performing, energy-hydraulic methods for determining the parameters of pumping units were used.

And Performance

As a preventative management mode, integrity management which is significantly effective is now applicable in modern industry. Based on the successful application of integrity management for the pipeline, managers expect an extension of the integrity management program for the oil and gas stations such as pumping stations, so as to make the best arrangement of resources and guarantee the safety of station facilities. The differences between station integrity management system in China and abroad are analyzed. It is claimed that the oil and gas station integrity management is more difficult and complicated in China. An integrity management program is developed for the oil and gas stations in China. The authors summarily introduce the station integrity management framework, and determine the processes and elements of management. For the main parts of the stations are plenty of facilities, the authors attempt to carry out the management on each category of facilities in particular. According to the characteristics and working status, field facilities can be classified into three categories: static facilities, dynamic facilities, and electrical instruments. For all these facilities, integrity management approach consists of five steps: data collection, risk assessment, integrity assessment, repair & maintenance, and performance evaluation. Station integrity management system comprises five aspects: system documents, standards & specifications, supporting technologies, management platforms and applications. This paper should be considered as a reference for the oil and gas station integrity managers in the future.
