This article focuses on the possibility of using technology in Azerbaijani for drilling into low pressure regions that would not normally be possible using classical methods. To meet the growing demand for technology in oil production in Azerbaijan requires comprehensive solutions that ensure safe and efficient drilling with a negative differential pressure.
A method based on a multifractal approach is suggested in order to diagnose the current state of layer system. This method allows on-line decisions to be made concerning regulation and control of exploration for oil deposits. Undermultifractal fluctuation method field data analysis the dynamic change of generalization fractal dimension for time series of current oil production was investigated. The dynamic analysis evaluates self organization of the development process, aimed at selection of the most efficient stimulation methods and their purposeful correction at different stages of field exploitation.
In accordance with established composition of complex fishing tools for emergency response equipment for downhole ESP we have developed the principal design for fishing equipment for emergency response in wells operated by ESP. The presented scheme can simplify the ESP work over and accelerate their re-entry into service after repairs.
Many deposits are characterized by a high degree of depletion of reserves and water cut. Production of most fields in Western Kazakhstan (30) are high-paraffin and viscous oil. These include "Uzen", "Zhetybai", "Karamandybas", oils which are extremely rich in dissolved paraffin (26%), resins and asphaltenes (20%) and contain corrosive gases (H2S, CO2). In this regard, this paper analyzes the effectiveness of enhanced recovery of oil from the "Zhetybai" field. The analysis of commercial materials identified the amount of work by type of technology used. The effectiveness of the technologies for intensification of oil was determined in several ways: by an increase in oil rates, the increase in specific productivity index and the stocks involved. The effectiveness of injection wells was estimated from the increase in oil production in the surrounding wells. As a result, the conclusions of the study reccomend to increase the productivity of wells by means of stimulation and the bottom-hole zone.
On the basis of a theoretical study the quantity of deposits in pipeline transportation of oil is determined. It is shown that with increase in pipeline capacity the deposit velocity also increases and at the lowest working capacity of pipeline (Q = 300 m3/hour) hardly any sediments appeared over a period of 150. The velocity also increases with increasing deposit density. According to the analytical formula obtained, numerical calculation has been carried out on example of the oil pipeline Dubendi-Beyukshor, Dashgil-Puta and the mass of different deposits depending on time at several rates is determined. It is established that during the initial period deposits of paraffinasphalt-resin compounds of sand and sulphur occurred rapidly and then decreased.
The standard procedure for determining the permeability of porous media according to APZ Code No. 27 (first edition, October 1935) is based on the fundamental assumption that, as long as the rate of flow is proportional to the pressure gradient, the permeability constant of a porous medium is a property of the medium, and is independent of the fluid used in its determination. Although this is true for most liquids, the permeability constant as determined with gases is dependent upon the nature of the gas, and is approximately a linear function of the reciprocal mean pressure. This effect can be explained by taking into account the phenomena of slip, which are related closely to the mean free paths of the gas molecules. The apparent permeability extrapolated to infinite pressure gives a permeability constant which is a characteristic of the porous medium only.
In work it be proved that the partial differential equations which describe nonstationary filtration of homogeneous liquid in crack-porosity medium are parabolic by Petrovsky system of equations. The initial-boundary problem of nonstationary liquid filtration in crack-porosity medium with circular form is considered at boundary conditions on external border of reservoir in view of present of two mediums. The conditions of existence and uniqueness for problem’ solution have determined.
