Study of boundary layers of oil and water in the case of reservoir floodin

Key words: residual oil saturation, NMR method, boundary layer of bound oil, surface wettability, viscosity, asphaltenes, resins.

The article presents the results of complex NMR-study of natural and model oil boundary layers properties on the surface of the pore channels of reservoir rocks after flooding. It is found that the thickness of the boundary layer is a function of permeability, residual water, wetting and surface temperature. It is shown that asphaltenes are the main components of the anomalous boundary layers of oil in the pore channels of the collectors. To minimize the thickness of the boundary layers of oil the effect of thermal, chemical, acoustic and magnetic influence is investigated. It is shown that the maximum effect is observed in the thermal and acoustic methods, in which the effectiveness is a function of the external energy input.

Key words: eismic surveys, Slip-Sweep method, spread shooting, vibroseis source, performance rating.

The paper presents the experience in performing the MOGT-3D seismic and exploration jobs on an industrial scale using the Slip-Sweep method. It was illustrated that the application of this method exceeds the classical seismic study by the parameters like tine to perform the jobs, information content in the materials obtained in challenging seismic/geological and surface conditions. Slip-Sweep method was initially applied on a commercial (for 455 sq. km) and not a test mode at the Russian territory. Considering the fact that the performance of these jobs became possible in the conditions with highly-developed infrastructure, in the areas with high forest coverage, at the agricultural lands with numerous rivers and cross-country terrain the authors consider that the performance of these jobs based upon Sleep-Sweep method is perspective also for other Russian regions.

Influence of low-amplitude tectonic faults on the effective development of multizone fields of Western Siberia

Key words: reservoir, fracturing, strike-slip faults, well productivity, well efficiency.

The strike-slip faults at the bottom of the sedimentary cover have a great influence on the higher reservoirs of the cross-section and where a porous reservoir is expected, there can be a porous-fractured reservoir. In some cases, benches meet vertical nonuniformity that’s appeared at the lower Jurassic and has tectonically conditioned genesis. These zones are a complex of small faults and they can’t be recorded definitely with the help of standard seismic methods, but they have a great influence on the well work.

Extension of sucker rod pumps’ application for well-to-well formation water pumping

Key words: well-to-well water pumping, high wellhead pressure, sucker-rod pumping units, novel wellhead and downhole equipment, extension of application range.

Application of conventional sucker-rod pumping units for well-to-well formation water pumping to energize formation in waterflood pool development projects is commonly limited by high loads on sucker rods and failure to seal polished rods at high pressure. The paper discusses the extension of sucker-rod pumps’ range of application for well-to-well water pumping. The solutions provide for a downhole booster pump and a plunger-and-barrel assembly located below the polished rod to ensure a reliable sealing. The algorithm has been specified; also, the results of calculations related to the extension of application range in terms of the vertical head at 14 MPa wellhead pressure are presented.

Heat exchange calculation at the design of the condenser of seasonally acting cooler unit

Key words: finning, heat exchange, condenser, seasonally acting cooler unit, permafrost soil.

The attempt to define the coefficient of heat transfer from the surface of the condenser of seasonally acting cooling unit is made. The calculation takes into account features of the geometric parameters of the condenser (fin size and spacing, the size of the pipe), and also the finning material. According to the results of the developed technique the bundled software, which allows to simulate the processes of condenser heat exchange and to determine the most optimal finning design parameters, is created.
