Method and results of the investigation of the field of permanent magnets action on the rheology of anomalous oils of the Timan-Pechora Oil and Gas Province

In this paper, we investigated the effect of a magnetic field on the flow curves and the viscosity of anomalous oils in the flow-through processing mode and com-pared the results with the effect of heat treatment. An experimental setup was devel-oped to study the effect of a constant magnetic field of different configurations on the rheological characteristics of oils in steady state and flow-through conditions.

Effect of dissolved gas in oil to technological development indicators under thermo-roasting method of oil production

Hydrodynamic modeling of the Yarega oilfield block was considered for the first time. The block is developed by thermo-mining method. Influence of dissolved gas in oil on technological indicators of development is considered. The positive effect was revealed of dissolved gas on oil production. The mode of the dissolved gas is activated when heat is applied to the reservoir of the Yarega oilfield. Activa-tion factors: oil viscosity reduction; separation of dissolved gas from oil; tempera-ture expansion of free gas. The current energy state of the reservoir makes it possi-ble to use the hydrodynamic model without taking into account the dissolved gas. Problems in numerical modeling are revealed. These problems are related to the quality of the source information. The authors have developed recommendations for eliminating problems.

The application of the theory of catastrophes in the diagnosis of tube bundles of gas air-cooling apparatus at compressor stations

The article deals with the application of the theory of chaos in the diagnostics of tube bundles of gas air coolers at compressor stations. On the basis of the works carried out, it has been established that periodic cleaning of the surfaces of gas air-cooling apparatuses, taking into account the local state of the surfaces of the apparatuses, is ineffective. Based on the theory of catastrophes, a method for estimating the state of the surface of air-cooling devices is proposed, which makes it possible to analytically monitor the intensity and nature of the accumulation of contaminants.

Improvement of technology for development of high-viscosity oil deposits with low thickness

The article presents the developed technology to improve the efficiency of in-volving the reserves of high – viscosity oil concentrated in complex reservoirs, the effective oil-saturated thickness of which does not exceed 6–15 m to maximize the extraction of hydrocarbons, it is proposed to use a horizontal well, which will serve as a production and injection well. One of the main problems is the ability of deep pumping equipment to operate at high temperatures during steam injection. Nevertheless, this problem is solved with the help of new developed technical means

Comparative analysis of the efficiency of various acid compositions and demulsifiers in production wells

Experiments have been carried out to evaluate the efficiency of dissolving car-bonate deposits. The effect of the reactant on the change in the filtration characteris-tics of a carbonate porous medium has been studied. The selection of components for an oil-acid compound based on the chemical product Sulfoil-K for acid fracturing in high-temperature wells was carried out. We showed the possibility of using the Sul-foil-K chemical product as a basis for preparation of acid compounds for cleaning the downhole pumping equipment from deposits of carbonate salts, as well as and additive for preparation of a filter cake removal compound based on hydrogen perox-ide. A comparative analysis of the demulsifiers Reapon OFC-D and Divoil was car-ried out.

Research and formulation biopolymer bridging of the mixture for elimination of lost circulation in permeable rocks

The studies of many domestic and foreign scientists, as well as field experience in drilling operations show that acquisitions are one of the most common and costly types of complications. Therefore, the development of drilling technology in condi-tions of acquisitions is an important task and requires comprehensive study to ensure high-quality insulation of high permeable rocks. However, the situation is complicat-ed by the diversity of mining and geological drilling conditions and absorbing layers, which can vary widely, resulting in the use of “traditional” and the same methods of elimination of acquisitions is ineffective. It is shown that one of the promising and ef-fective methods of absorbing layers isolation is mudding. The article presents part of the experimental studies for determining the intensity of mudding from time to time using a high temperature press high pressure filter. Developed by biopolymer bridg-ing of the mixture to effectively collaterality highly permeable ceramic filters in a relatively short time.

Analysis of the solvent capacity of various hydrocarbon solvents for various types of asphaltene, resin and paraffin deposits (ARPD)

The efficiency of hydrocarbon solvents for ARPD on the basis of by-products of petrochemical products is evaluated. The dissolving efficiency of the absorbents A2, Bottom Residue of Benzene Distillation (BRBD) and Bottom Residue of Ethyl Ben-zene Distillation (BRED) and compositions based on them is defined. It has been found that the solvent capacity of petroleum solvents with respect to ARPD grows as the content of aromatic hydrocarbons increases. Recommendations have been made to enable the hydrocarbon solvent to penetrate the inner layers of ARPD through a water film enveloping asphalt-resin and paraffin agglomerates.

Nonstationary properties of the flow curves of anomalous oils

Experimental studies of the thixotropic properties of the high-paraffin oil of the Kyrtayolskoe field and the high-viscosity bituminous oil Usa permo-carbon field were carried out in the work. Flow curves for different temperatures are recorded, hyste-resis loops are fixed, and loop area dependences, characterizing the degree of thixot-ropy, are plotted against temperature. An experimental method for measuring non-stationary parameters of thixotropic oils using a pulse-intermittent method of defor-mation of an oil sample and recording a flow curve was experimentally realized.
