The article analyzes the causes and factors reducing the key indicators of quality and efficiency of construction and operation of wells, which led to a prolonged stagnation in drilling technology. To solve the urgent problems, a systematic approach of multi-technologies set implementation of hydromechanical strengthening of an open wellbore by the synchronized and coordinated action of drilling fluids’ hydro-monitor jets is proposed. The indicators of quality and efficiency of the multi-technologies set, twice or more times exceeding the traditional one, are presented.
Keywords: consistency; multi-technology; thermodynamic processes.

THE STRATEGY OF EXPLORATION DRILLING IN THE RUSSIAN ARCTIC SEAS IN MODERN CONDITIONS (p. 6)

The modern heightened interest of leading world powers in the Arctic is not accidental. The Russian Arctic shelf is considered the most important reserve of hydrocarbons and it is here possible to open large, very large and unique deposits. Exploration drilling in the Arctic seas has already got more than 40-year history. Oil and gas operators accumulated considerable experience in organizing and carrying out exploration drilling during this period. However, it should be noted that there exist significant differences in the strategy of exploration works conducting in the US-Canadian sector and the Russian sector of the Arctic. In the first case, the drilling was carried out year-round due to the development and use of the artificial island equipment and technologies, while on the Russian Arctic shelf it was conducted in the open water conditions. At the sea depths greater than 100 m the wells on the US-Canada Arctic shelf were not drilled, while on the Russian Arctic shelf the entire range of depths available for work of floating rigs was covered by drilling. However, drilling in the areas of the extreme shallow waters (or so-called «transit zone» – up to 5…10 m) has not been conducted in Russia. The current situation analysis as per the design of high icy-class floating drilling rigs of different types both in Russia and abroad shows that their development is at the stage of conceptual projects and cannot be implemented in the near future. Herewith, in the Russian Arctic drilling from artificial islands (including those made of ice), i. e. by more available technologies, is neither carried out now nor it was previously. It should be emphasized, that drilling from artificial islands does not require imported equipment, because the well is built by the traditional technique. Water operating depth for artificial icy islands is 8 m, although the islands can be used to the depth of 12 m without any problems. Further research and development can widen the possibility of artificial icy islands use at greater depths, and make this type of constructions even more reliable and safe.
Keywords: the Arctic; oil and gas production; exploration drilling; drill rig; icy conditions; floating icy platforms; artificial icy islands; water freezing; water spraying; icy road; winter drilling time.

MODERN METHODS OF CONTROL OF A WELLBORE CLEANING QUALITY (p. 16)
Yury Alexandrovich Dobik
LLC «RN-Vankor» 15, 78th Dobrovolcheskaya brigada str., 660077, Krasnoyarsk, Russian Federation, phone: 8-918-011-09-55, e-mail: dobiik83@gmail.com
The article analyzes the methods applied nowadays to control a wellbore cleaning quality of inclined or horizontal wells. It is shown that the well-known devices, used to control drill cuttings amount on the surface, fail to correctly estimate the amount of drill cuttings that are left in the well. Some method of the reliable estimation of the wellbore cleaning quality, based on the amount of the extracted rock removed from drilling site by trucks, is developed. The purpose of this method is to avoid drilling problems associated with poor cleaning of wellbores.
Keywords: wellbore cleaning from the drilled rock; inclined and horizontal wells; drilling characteristics; shale shakers; drilling problems; drill cuttings.

The article provides a streamlined scheme of the absorption process of dioxide (CO2) by methanol to purify oil associated petroleum gas and natural gas with CO2 high content. The technological scheme proposed by the author is based on a relatively high methanol dehydration by means of ÊÀ-Y-brand zeolite followed by dried methanol use as an absorbent for natural gas dehydration in the absorber. The efficiency of the proposed scheme depends on the quality of the methanol to be dried.
Keywords: absorption; adsorption; zeolite of ÊÀ-Y brand; absorber; methanol; natural gas; associated petroleum gas; high pressure column; carbon dioxide.

Transportation of oil and gas leads to the formation of hydrates and complications in the field equipment. To prevent gidratatini at the fields used by various inhibitors. They are expensive and have several disadvantages. The proposed automated pipeline heater PT – P/D for heating oil, gas. As fuel for heating is flare gas. The paper presents experimental studies of the application of heaters of this type, and confirmed the feasibility of their use for combating hydrates to reduce the viscosity of the oil, removing deposits of paraffin.
Key words: oil; hydrate formation; pipeline heaters; flare gas.

At present the wells in Astrakhan gas-condensate field are constructed by washing with the help of Katburr polycationic drilling muds. Use of polycationic systems when constructing wells No 939 and No 1082 in the salt section provided reduction of chemical reagents, increase of drilling mechanical rate and wellbore stability, decrease of time, required for reaming and washing, etc. Thus, application of Katburr polycationic systems in the salt section of Astrakhan gas-condensate field provides improvement of wells construction quality, decrease of material costs and drilling time.
Keywords: polycationic drilling mud Chatburn; well; mechanical velocity; the salt deposits.
