SOME PROBLEMS OF PIPELINE TRANSPORT OIL AND OIL PRODUCTS
http://www.ogbus.ru/authors/Hamzayev/Hamzayev_1.pdf (in Russian)
Work is devoted to research of some questions of pipeline transport of oil and oil products. In the first part of work the problem of a choice of an operating mode of the pump station located on the set site of the pipeline is considered, and in the second part the problem of detection of outflow of oil and oil products in pipelines is investigated.
For the mathematical description of problems the one-dimensional mathematical model of stationary movement of a viscous liquid on the pipeline is used. Thus pressure and the mass charge of a liquid in initial and final sections of the pipeline are considered set. The analytical method of the decision of tasks in view is offered and obvious formulas for definition of an operating mode of pump station, the mass charge on outflow and places of outflow in the pipeline are received.

http://www.ogbus.ru/eng/authors/Fyodorova/Fyodorova_1e.pdf (in English)
http://www.ogbus.ru/authors/Fyodorova/Fyodorova_1.pdf (in Russian)
The paper considers compatibility of formational water of the Irelyakh gas and oil field of the Republic of Sakha (Yakutia) with the highly mineralized solution used as an agent of reservoir pressure maintenance (RPM) with an allowance for factors, which influence solubility of salts, salt effect in particular. Also, possibility of concurrent reactions and specific conditions characteristic of the fields of the southwest Yakutia (by the example of the Irelyakh GOF) have been taken into account. It is shown that with the increase of the time length of wells' flooding with the liquid for RPM the pore space structure undergoes changes due to its calcination and sulphatization, which causes deterioration of reservoir properties and subsequently can complicate the operation of producing wells and the field in the whole.

The analysis of spatial and temporal changes of physical and chemical properties of oils with the high paraffins contents is carried out. The regularities of regional distribution of such oils are considered. Particularities of change of the paraffins contents in oils are investigated depending on occurrence depth. Regularities of changes of oil properties in geological time are considered. It is shown, that the maximal value of the paraffins contents in such oils is observed in Mesozoic and the minimal value - in Proterozoic rocks. Paraffinic oils are on the average low sulfur, resinous, low asphaltenes and with the average contents of fraction IBP 200 0Ñ and with average density.

FEATURES OF FLOWVISION AND ANSYS SOFTWARE'S COMBINED USE FOR THE DETERMINATION OFSTRESS CONDITIONS IN OIL TANKS
http://www.ogbus.ru/eng/authors/Lukyanova/Lukyanova_2.pdf
During operation of vertical cylindrical tanks for storage of oil and oil products significant quantities of compacted sediments can be formed and accumulated. As a result, tank useful capacity, tank farm turnover are reduced, oil storage cost is increased due to the necessity to put tanks out of operation and perform their cleaning. There are methods of cost reduction in case of timely removal of forming sediments by using, for example, various screw-type devices.
In order to determine deformed condition of the tanks during washout and mixing of sediments with movable oil jet produced by operation of the screw-type devices, flowvision and ansys software systems were applied. The article describes some features of solving the task.
