Заглавие: Study of the processes occurring at interaction of formation water of the irelyakh gof with the highly mineralized agent for reservoir pressure maintenance

Количество страниц: 8 с.

The paper considers compatibility of formation 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.

Заглавие: Hydrocarbon solvents on the hexane base for oil organic deposits elimination of the irelyakh gas and oil field

Количество страниц: 8 с.

The group composition of asphaltene-resin-paraffin deposits (ARPD) in the Irelyakh field and their solubility in the composite solvents on the hexane base with the additives consisting of nonionic surface-active substances (NSAS) and concentrates of aromatic hydrocarbons is determined. The results of the investigations show that the additives Neonol AF-9-10 and liquid products of pyrolysis (LPP) are most efficient. The use of these additives allows to increase the efficiency of ARPD breaking and dissolving by 1,3 – 1,6 times as compared with a base solvent. It is shown that the increase in the concentration of individual additives from 0,5 to 3 % causes a decrease in the efficiency of detergent compounds.

Заглавие: Study of possible using the polymer solutions as agents of oil displacement in the fields with abnormally low reservoir temperatures

Количество страниц: 12 с.

Rheological, structural and oil displacing properties of the solutions of polyacrylamide (PAA) and carboxymethylcellulose (CMC) are fully investigated in the conditions of abnormally low reservoir temperatures. Physico-chemical processes occurring at a contact of highly mineralized formation water with the polymer solutions of PAA and CMC, which are different in composition, in the pore space of the reservoir are studied. The possibility of increasing the efficiency of hydrodynamic influence on the reservoir in the conditions of the fields of the southwest Yakutia due to the use of displacing compounds on the water-soluble polymer base is established experimentally.

Заглавие: Dynamics of the Ionospheric Convection Systems Observed during The Super-Storm on Nov. 20, 2003

Количество страниц: 3 с.

In the accompanying Papers 1 and 2 was fulfilled timing of the 20.11.05 super-storm. Were detected 4 various types of the magnetospheric disturbances observable at southward IMF, and presented a new model of the field-aligned currents density spatial distribution in the polar ionosphere. In this paper are described the ionospheric convection systems, characteristic for the above various types. Are mentioned the mesoscale spatial inhomogeneities, which are observed more or less regularly but have not been mentioned in the past literature.

Заглавие: Dynamics of the Field-Aligned Current Systems Observed during The Super-Storm on Nov. 20, 2003

Количество страниц: 4 с.

Spatial distribution in the polar ionosphere of field-aligned currents density is studied by using data of the events on 20.11.03. Observable distributions are described in terms of three Regions of Iijima and Potemra, with taken into account in each Region of three types of spatial inhomogeneities. These inhomogeneitie were overlooked earlier. Dynamics of classical substorm current wedge SCW1, and the "current wedges" SCW2 and SCW3, both creating a polarization and amplification of the westward auroral electrojet, are described.

Заглавие: Laser processing of plasma sprayed coatings

Издательство: [s. n.]

Год выпуска: 1988

Количество страниц: 14 с.

The influence of continious CO2-laser processing on structure, composition and microhadness of plasma sprayed Ni-Cr-Si-B, Fe-C-Cr-V, Ni-Al coatings was studied. The change of chemical and phase compositions of the coatings compared with the initial sprayed ones due to alloying with elements of substrate, depending on the processing operation (input power) was determined. Laser processing of plasma sprayed coatings allows to improve substantially their adhesion and in combination with high speed cooling, gives the possibility to regulate the processes of structure formation, dispersion, phase formation, and hence, the properties of forming coatings by means of processing operation.
