Sealing Of Oil Reservoir As A Result Of Deformation And Sedimentation Of Various Additives

Ab.H. Rzayev, G.I. Kelbaliyev, S.R. Rasulov, G.R. Mustafayeva, V.V. Orujov

It is necessary to mention that a lot of macroscopic parameters of oil reservoir depend on its porosity, change of which is determined by the natural sealing and clogging of pores with various additives and the asphalt-resin compositions. The equation of porosity flow rate is based on the mass-transfer during the laminar and turbulent regimes. The damping of fil- tration process is described as model of relationship between permeability coefficient and porosity in time. A provided comparison between the theoretical and experimental values of flow rate shows a satisfactory conformity and the damping pulsation character of the rela- tionship between the filtration speed and time.

Technogenic Impacts From Exploration And Exploitation Of Hydrocarbon Reserves And Carbon Pollution Problems Of The Caspian Sea

M.I. Aliyev, N.Z. Askerova

The problems of technogenic impact of oil and oil products on the environment are reviewed in this paper. The ecological problems associated with the well drilling and a variety of meas- ure to free the oil-field areas from the drilling waste and contaminants are disclosed in details. The condition analysis is provided and a method of modeling of non-linear dynamic regres- sion is proposed to predict the levels of oil pollution of the Caspian Sea. The ways are set to ensure the environmental security and the regional cooperation in the field of environmental activities in the Caspian Sea.

E.E. Hasanov

The paper presents the calculated dependences that allow to fully analyze the stress-de- formed state of the bottom of docking structures employed in hydraulic engineering and erected on the swelling clay using the Fuss-Winkler model.

The Theoretical Analysis Of Crude Oil Vapour Pressure And Cavitational Technologies Studying Of Physical And Chemical Properties Of Transported Oil In The Course Of Cavitation

V.H. Nurullayev

Vapour pressure testing is an important safety check in the transport, storage and blending of crude oil.In article the general information about cavitation is resulted and at present and conditions- known at present and consequences of its occurrence, as hydraulic phenomenon are listed. It is noticed, that despite negative influence cavitations’ the phenomena can be used it for the useful purposes.And also application of these effects in meso is shown and micro-spaces with new nano-objects expands the list of possible perspective technologies. Under laboratory conditions were analysis physical - chemical features oils Azerbaijan with small content paraffin on borders cavitation the zones which results are resulted in the table. The carried out researches show that having applied cavitation technologies to oils and to mineral oils, it is possible to im- prove them rheological characteristics and quality indicators. On the basis of the resulted facts, perspectives of application cavitation technologies affirm at transport and oil refining.
