XX Международная научно-практическая конференция имени профессора Л.П. Кулёва512for the contact time 0.5, 1, 5, 15, 30, 60 and 150 minutes. The values of specific surface and specific pores volume for the sorbent and its components are shown in Table 1. As evident from the table, the active compo-nent in the form of iron oxyhydroxide and the pre-pared sorbent had the most values. One the other hand, the lowest parameters of specific surface and specific pores volume were characteristic of the he-matite and the aerated concrete. The results of the sorption experiments are shown in Figure 1. It can be seen from the figure that already in the first minute there is an almost complete purification of the model solution from As (III) ions at a concen-tration of 5.17 mg/dm3. The solution with a concen-tration of 40.21 mg/dm3 with a small process time is cleared worse and only after prolonged contact with the sorbent, the degree of extraction is almost equal to the degree of extraction from solutions with smaller concentrations of arsenic.References 1.

APPLICATION OF OPTIMIZATION TECHNOLOGY FOR THE STUDY OF THE CHEMICAL AND PETROPHYSYCAL PROPERTIES CONTAINER ROCKV.A. MorevScientific adviser – PhD, associate professor O.S. ChernovaNational Research Tomsk Polytechnic University 634050, Russia, Tomsk, 30 Lenin Avenue, viktmorev@rambler.ruEffective conducting of geological exploration complex and subsequent construction of geological models of oil and gas fields are possible only with full study of core samples.The rocks which form the oil-bearing forma-tions are filled with hydrocarbons, that is why, it is essential not just to be aware of mineral composi-tion of rocks, but also know the chemical and petro-physical properties of the reservoir rocks (carbonate content, apparent porosity, gas permeability, densi-ty, clay content, compressibility, residual water sat-uration, wettability, electrical resistivity, etc.).Techniques effectiveness increasing is a cru-cial direction in improving the methodological ap-proaches which are used to conduct laboratory stud-ies of core samples.The purpose of this work is to study the fea-sibility of practical implementation of method-ological approaches which allow to improve the efficiency of the sample preparation process during petrophysical studies.It is known, that for conducting standard and special studies, core samples undergo several stag-es of sample preparation, including cleaning and drying process. During cleaning oil, bitumen, water and salts are eliminated from pore spaces. Then, af-ter extraction, but before drying, it is necessary to split samples into 2 groups [1, 2]. The first group of samples with high clay content (> 30 % clay miner-als content) must be dried at a temperature of 70 °C. However, Standards of both countries do not spec-ify the procedure of how to select heavily clayish core samples from all core samples.Thus, it is worthwhile to note that the gran-Table 1.

The degree of transparency of water solution of meth-ylene blue after the interaction with the rock was analyzed.In the present work, the general mineralogi-cal compositions of samples were determined us-ing x-ray phase analysis (XPA). The mineralogical compositions of the samples were determined from the ratio of principal diagnostic reflections in dif-fraction patterns obtained under rigidly constant ex-posure conditions with observance of special safety requirements for working with sources of ionizing radiation.The optical density of the indicator solution was determined on a KFK-3-01 photoelectric pho-tometer using the optimum spectrum recording conditions. Solution optical density was measured at wavelength 665 nm, which corresponded to the absorption maximum of an aqueous solution of methylene blue. For the experiment, several samples from the productive formations of the Western Siberia region were taken, represented by fine-grained sandstones. It is crucial to note that for siltstones and sandstones visual determination of clay content is the most dif-ficult procedure. The clay content in the samples varies from 14 to 33 %. Clayey minerals were primarily kaolinite and chlorite. Water solutions after interaction with the sam-ples with high clay content (> 30 % clay minerals content), do not have any color. Consequently, the temperature in oven, where dry core sample, should not exceed 70 °C.Thus, indicator solution method in laborato-ry practice of chemical and petrophysical studies makes it possible to increase the efficiency of clay minerals content determination. It is crucial to note, that incorrect core samples separation based on their clay content may cause the structural damage of their pore space.References1. ASTM (2013).

INVESTIGATION THE EFFECT OF DIESEL FUEL FRACTIONAL COMPOSITION ON THE EFFECTIVENESS OF LOW-TEMPERATURE ADDITIVESY.P. Morozova, N.S. Bagdasaryan, I.A. BogdanovScientific adviser – PhD-student I.A. BogdanovLinguistic advisor – PhD-student I.A. BogdanovNational Research Tomsk Polytechnic University 634050, Russia, Tomsk, 30 Lenin Avenue, yanamorozovaa@mail.ruThe consumption level of the diesel fuel (DF) in Russia considerably increases every year. The climate of some country regions is cause of need for winter and arctic brand of diesel fuels. The simplest way to achieve the required low-temperature prop-erties of the fuel is the using of additives. However, additives effect different on various fuels, because of existence of interaction between the additives components and the hydrocarbons which diesel consist [1].
