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: Monoalkylbenzenes in oils of the Vendian-Cambrian deposits

Количество страниц: 10 с.

Peculiarities of the distribution of high-molecular normal alkylbenzenes in the Vendian-Cambrian oils of the Siberian platform are studied according to the data of chromatomass-spectrometry. The predominance of high-molecular homologues with the odd number of carbon atoms in a molecule is established. The possible biochemical precursors and the probable mechanism of the formation of “odd” monoalkylbenzenes are suggested.

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: The effectiveness of energy resources and successive technological stages

Количество страниц: 12 с.

This article discusses criteria for comparing the effectiveness of energy resources. It focuses on the interrelationship between the effectiveness of energy resources and movement from one technological stage to another. What emerges is the consistent pattern of change in existing technologies, and increasingly evident is that, at their current stage of development, neither nano- nor biotechnology will lead to an evolution from the current and fifth technological stage to a sixth. Of note is that at present oil remains the key energy resource, which means that in the near future peak oil will force us to confront an unprecedented event in industrial history: energy degradation, which can be viewed as a regressive movement in the existing technological stage.

Заглавие: Study of the methane hydrates obtaining process in static conditions

Количество страниц: 10 с.

We have studied the process of artificial methane hydrates obtaining in static conditions from distilled and "secondary" water (prepared by the decomposition of methane hydrate), as well as the additional metal surface using inside of cameras. It was found dependence from the type of the liquid phase and the presence/absence of additional metal surface inside the camera; in the same initial conditions of temperature and pressure, it can be obtained samples with different degrees of transformation of the "water-gas" to hydrate and various crystalline morphology.

Заглавие: Use of a kinetic study for the effectiveness evaluation of asphaltene-resin-paraffin deposits (ARPD) solvents

Количество страниц: 8 с.

The process of the paraffin type asphaltene-resin-paraffin deposits dissolution in the alkane base gas condensate, hexane-benzene mixture (HBM) and hexane at 10 and 25°C is investigated. These deposits are formed during oil production in the Irelyakh field. The comparative effectiveness evaluation of studied solvents is performed by the widely used in practice "baskets" method and the results of kinetic studies.
