In the "Energy Strategy of Russia until 2030" even set an indicator of the strategic development of the oil complex "increase oil recovery from 0.3 to 0,35-0,37." However, what these values ​​of CIN, as far as they are relevant and consistent with the realities of oil production in Russia? According to the author, in many cases are discussed and publicized in the press, as well as included in the official documents of little sound and strategic areas for action. Analysis of the key issues of oil extraction in Russia and the justification of the possible priorities for action in relation to international practice and the subject of this article. {Tab = ABSTRACT} At present there is a wide discussion in the country at various level related to EOR aspects during the oil field development process, that is referred to oil quality decrease in recoverable reserves and obvious drop in ultimate negative dynamics of design oil recovery factors. The 2030 Russian Energy Strategy contains the following strategic oil economy index of development as "to increase the oil recovery rate from 0.3 to 0.35 - 0.37". However, what is backing these indices up, what is the level of their urgency and whether these coincide the actual status of oil recovery in Russia? Following the opinion of the author mass media discusses and advertizes and official documents contain the poorly substantiated positions and strategic ways of actions. The present paper is dedicated to the analysis of Russian major problems in oil recovery and substantiates possible priorities on the way as compared to the international practice.

Аннотация

Представлен новый подход к очистке жидкости глушения. В настоящее время несколько десятков бригад ТРС в г. Нижневартовске и г. Ноябрьске постоянно и успешно применяют мобильные фильтры DUOFLO≥. Их внедрению способствовали, с одной стороны, обеспечение высокого качества фильтрата, с другой - легкость, удобство и экономия времени при обслуживании. Технология тонкой финальной фильтрации на устье скважины показала, что она применима даже в экстремальных зимних условиях.

ABSTRACT

The author presents the new approach towards well kill fluid treatment. At present several well maintenance crews in Nizhnevartovsk and in Noyabrsk are constantly and successfully using the DUOFLO≥ mobile filters. On the one hand their application had resulted in obtaining high-quality filtrate, and on the other hand it has provided the simplicity, convenience and time-saving during their maintenance. The procedure of final fine filtration at the well-head has shown that it is applicable even in the extremely cold weather conditions.
