Effective fluid-loss control in oil wells is a critical concern for the industry, particularly given substantial reserves situated carbonate reservoirs globally. The prevalence of such expected to rise with slow depletion hydrocarbons, intensifying need address challenges related deteriorating reservoir properties post well-killing operations. This deterioration results significant annual losses hydrocarbon production at major enterprises, impacting key performance indicators. To tackle this...
Acrylic polymers have been used in the oil industry since 1970s, and are considered to be highly effective as filtration reducers. Subsequently, influence of various homologues this series, well molecular weight, on aspects drilling mud functionality was revealed. After USSR collapse 1991, research base field acrylic polymer synthesis lost, a number developments were never brought industrial production, which competitors took advantage filled resulting vacuum. A stream imported poured into...
Introduction.Cement microstructure imaging is an emerging field of non-destructive compositional investigation.Some data may be available via one method but not the other due to various physical and chemical mechanisms that could cause cement decay.In order quantitatively qualitatively evaluate stone, it necessary investigate as a complex multi-phase composite material, identify its crystalline phases, estimate precise size nanoparticles.Materials methods.This work presents results...
В статье кратко рассмотрены особенности глубоководного бурения скважин на шельфе Гвинейского залива (Кот-д’Ивуара), а также промысловые данные по пробуренным скважинам, отмечены недостатки и пути совершенствования промывочных жидкостей. The article provides a summary of the characteristics deep-water drilling for wells on shelf Gulf Guinea (Côte d'Ivoire). Additionally, it presents field data drilled wells, identifies challenges, and suggests potential improvements to fluids.
In the current drilling technology today pointed out problems associated with instability of work downhole motors , they stop, short service life working devices (WD) and accidents (lapels, destruction elements DDM) layout drill string (DS). particular, timing engines, depending on size operating conditions, ranging from 90 to 235 hours. Failures DDM according companies Gazprom CSA Deutag» - 5 12 per year; which leads long-term recovery efforts in well, or complete elimination latter. From...
Рассмотрено программное обеспечение (ПО), как инструмент для проверки квалификации при приеме в штат кандидатов организации осуществляющих сервис бурении нефтяных и газовых скважин (НГС) с применением забойной телеметрической системы непосредственно буровых предприятии, а так же проблемы обучения принципам порядку проводки наклонно-направленных Учебно-Образовательных Учреждениях. Особое внимание уделено вопросу внедрения ПО соответствующие области применения технологии наклонно-направленной...
Most of the main types complications in process drilling wells, such as collapses, taluses, collapses walls, formation caverns, etc., are associated with external mechanical and hydrodynamic effects on walls wellbore. Therefore, ensuring stability borehole is one urgent difficult technological fluid pressure processes rocks when they opened a directional well, especially horizontal wells. This article provides solutions to problems hydraulic fracturing well condition its prevention,...
One of the complex technological tasks in process drilling is to ensure stability wellbore walls, as well their modeling for further forecasting state and likelihood hydraulic fracturing. This due fact that most complications factors affecting equilibrium wall are associated with external influences. The article discusses mechanical partially aspects solving described problems walls predicting As a result calculations, necessary data obtained making decision on density fluid considered...
Ensuring the completeness of oil and gas production from subsoil by using modern techniques technologies for controlling inflow into well is an urgent task, especially wells with long horizontal ends. Inflow control devices (ICD), used in conjunction packers downhole measurement devices, are part such systems, covered concept «smart well». In general, systems make it possible to (flow rate) individual intervals or vertical multilayer fields while operating simultaneously order optimize...
The almost ubiquitous complication of drilling conditions led to increase depth, namely longest measured depth extended-reach wells. use combination becomes more relevant. total weight the used drill string acquires an important role, since depending on friction and wear against borehole wall, as well general stress-strain state increase. An aspect in this issue is ensure reliable operation string, which extreme temperatures loads. latter significantly affects technical economic parameters...
Актуальность исследования состоит в том, что решением преждевременного прорыва воды или газа горизонтальной скважине из-за неоднородности профилей притока вдоль оси горизонтального ствола, является изменение пластового давления на различных участках, а также при разработке контактных месторождений, особенно по мере истощения залежи, могут служить устройства контроля флюида. Различают активные Interval Control Valve (ICV) пассивные Inflow Device (ICD) устройства. Устройства ICD способны...
The article discusses the development of technology for directional drilling oil and gas wells in perspective modeling downhole operations. most significant mathematical models developed by Soviet foreign scientists XX century are listed. An example calculating reaction on a bit based widely used method initial parameters is shown. In process typical calculation deflecting force bit, it was possible to set boundary conditions bottom hole assembly (BHA) supports natural form, using well-known...
В статье рассмотрены этапы разработки забойного бурового оборудования и развития технологических приемов для бурения наклонно направленных горизонтальных скважин (далее ННГС) в период с 20-х годов XX века до настоящего времени.

The article is about problem of drilling deepwater oil and gas wells that consists in complicating increasing cost their well design due to narrowing mud window at different depths. authors analyse technology developed applied practice offshore with a dual gradient drilling, which allows significant intervals without overlapping an intermediate casing string. Based on analysis these technologies taking into account disadvantages the proposed tested new placement all necessary innovative...
Improving the operational properties of lubricants increases service life mechanisms and increase durability rubbing joints, which has a positive effect on indicators technical economic efficiency equipment safety. Therefore, great attention in tribology is paid to analysis state friction units technology assessment their resource characteristics, makes it possible life. The research aim study general provisions lubricants, as well features boundary layers formation surfaces observed...
The use of several types drilling fluids is a compromise based on the need to maintain given project technological parameters (performance -inhibiting, rheological, tribological properties) during unstable clay deposits, at opening producing formation, ensure high quality well casing, etc. This especially true for construction wells with horizontal and directional zenith angle deposits more than 70 degrees. A new type emulsion muds developed, i.e. reversible invertible mud (RIDM). RIDM...
