Impact of hydrocarbon drilling mud on mud motor elastomers at different temperatures

The paper describes the experimental research of hydrocarbon drilling mud impact on engineering parameters of mud motor elastomer samples. It is believed to be urgent due to an increase in using mud motors in oil and gas well construction now, and the issue of intense exploitation is currently topical. The test results of elastomer IRP- 1226 dependent on the temperature are shown in the paper. It is proved that the hydrocarbon drilling muds have a significant impact on wearing of mud motors elastomers under the condition of a temperature increase

Vertical section construction of wells at Kuyumbinsky oil field via percussive-rotary drilling with DTH hammer

The article presents the analysis of sequential use of mobile percussive-rotary drilling sets with DTH hammer and bottom-hole cleaning by foam mud in construction of vertical sections along with at Kuyumbinsky oil field. On the basis of the analysis, an engineering solution is proposed to prevent disastrous mud loss that is the key factor of efficiency in implementation of resource-saving technologies

Climatic variability of the mean flow and stationary planetary waves in the NCEP/NCAR reanalysis data

NCEP/NCAR (National Center for Environmental Prediction – National Center for Atmospheric Research) data have been used to estimate the long-term variability of the mean flow, temperature, and Stationary Planetary Waves (SPW) in the troposphere and lower stratosphere. The results obtained show noticeable climatic variabilities in the intensity and position of the tropospheric jets that are caused by temperature changes in the lower atmosphere. As a result, we can expect that this variability of the mean flow will cause the changes in the SPW propagation conditions. The simulation of the SPW with zonal wave number <I>m</I>=1 (SPW1), performed with a linearized model using the mean flow distributions typical for the 1960s and for the beginning of 21st century, supports this assumption and shows that during the last 40 years the amplitude of the SPW1 in the stratosphere and mesosphere increased substantially. The analysis of the SPW amplitudes extracted from the geopotential height and zonal wind NCEP/NCAR data supports the results of simulation and shows that during the last years there exists an increase in the SPW1 activity in the lower stratosphere. These changes in the amplitudes are accompanied by increased interannual variability of the SPW1, as well. Analysis of the SPW2 activity shows that changes in its amplitude have a different sign in the northern winter hemisphere and at low latitudes in the southern summer hemisphere. The value of the SPW2 variability differs latitudinally and can be explained by nonlinear interference of the primary wave propagation from below and from secondary SPW2

APPLICATION OF INNOVATIVE MARKETING TOOLS IN EDUCATIONAL ACTIVITIES OF HIGHER EDUCATION INSTITUTIONS

The main tools of innovative marketing in the educational activities of higher education have been considered. Features and possibilities of their application have been defined. New conditions of educational activity have been designated. The necessity of using the marketing methodology in educational activities due to the active development of the higher education market has been substantiated. It has been proposed to allocate a separate place to marketing in the quality management system of educational services. The principles of quality management system of educational process of higher educational institutions on the basis of use of technologies and tools of innovative marketing have been defined. The improved schemes of interrelation and succession of processes of training have been offered. A set of parameters and indicators to assess the effectiveness of innovative marketing tools has been recommended
