При разработке водонефтяных зон наблюдается образование конусов подошвенной воды, что ведет к увеличению обводненности скважинной продукции и снижению коэффициента извлечения нефти (КИН). В качестве одного из методов борьбы с данным явлением возможно применение технологии, описанной в патенте RU 2 730 163 C1. В данной статье представлены результаты моделирования данной технологии в гидроди-намическом симуляторе. During the development of oil-water zones, the formation of bottom water cones is observed, which leads to an increase in the water cut of the well production and a decrease in the oil recovery factor. As one of the methods to combat this phenomenon, it is possible to use the technology described in patent RU 2 730 163 C1. This article presents the results of modeling this technology in a hydrodynamic simulator.

The quality of feedstock used in base oil processing depends on the source of the crude oil. Moreover, the refinery is fed with various blends of crude oil to meet the demand of the refining products. These circumstances have caused changes of quality of the feedstock for the base oil production. Often the feedstock properties deviate from the original properties measured during the process design phase. To recalculate and remodel using first principal approaches requires significant costs due to the detailed material characterizations and several pilot-plant runs requirements. To perform all material characterization and pilot plant runs every time the refinery receives a different blend of crude oil will simply multiply the costs. Due to economic reasons, only selected lab characterizations are performed, and the base oil processing plant is operated reactively based on the feedback of the lab analysis of the base oil product. However, this reactive method leads to loss in production for several hours because of the residence time as well as time required to perform the lab analysis. Hence in this paper, an alternative method is studied to minimize the production loss by reacting proactively utilizing machine learning algorithms. Support Vector Regression (SVR), Decision Tree Regression (DTR), Random Forest Regression (RFR) and Extreme Gradient Boosting (XGBoost) models are developed and studied using historical data of the plant to predict the base oil product kinematic viscosity and viscosity index based on the feedstock qualities and the process operating conditions. The XGBoost model shows the most optimal and consistent performance during validation and a 6.5 months plant testing period. Subsequent deployment at our plant facility and product recovery analysis have shown that the prediction model has facilitated in reducing the production recovery period during product transition by 40%.

Исследована зависимость выхода масла, массовой доли сырого протеина и остаточной масличности в жмыхе от содержания плодовой оболочки в перерабатываемом материале. Объектом исследования была ядровая фракция семян дыни сорта Амири, выращенной в Таджикистане. Предварительно семена дыни масличностью 35,3 обрабатывали ИКоблучением с нагревом до 90С. Затем их обрушивали однократным ударом в модернизированной центробежной рушке. Из полученной рушанки готовили образцы модельной смеси ядровой фракции семян дыни с содержанием плодовой оболочки 8, 14, 20 и 25. Перед отжимом масла каждый образец ядровой фракции нагревали до температуры 6870С в установке с ИКэнергоподводом. Влажность образцов составляла (6,0 0,2). Отжим масла из семян дыни проведен в стендовых условиях на шнековом прессе DUO (Farmet a.s., Чехия) при установленных оптимальных параметрах работы шнекового пресса: частоте вращения вала 40 об/мин диаметре выходного отверстия съемной насадки 6 мм величине зазора между основанием шнека и прессующей головкой 3 мм. Установлено, что при снижении содержания плодовой оболочки в ядровой фракции до 8 выход дынного масла увеличивается до 37, содержание сырого протеина в жмыхе на абсолютно сухое вещество повышается до 56, масличность получаемого жмыха уменьшается до 9. При этом улучшаются качественные показатели дынного масла. По результатам исследований получены уравнения для расчета показателей выхода дынного масла, содержания сырого протеина и масличности жмыха в зависимости от содержания плодовой оболочки в ядровой фракции семян дыни, которые можно использовать для оперативного управления технологическим процессом и прогнозирования показателей качества получаемой продукции. The dependence of the oil yield, the mass fraction of crude protein and the residual oil content in the cake on the content of the fruit shell in the processed material was investigated. Sound fraction of melon seeds variety Amiri grown in Tajikistan has been the object of study. Preliminary melon seeds with oil content of 35,3 were treated with IRirradiation heated to 90C. Then melon seeds were brought down by a single blow in a modernized centrifugal hulling machine. From the obtained hulling seeds samples of the model mixture of the sound fraction with the content of the fruit shell 8, 14, 20 and 25 were prepared. Before pressing the oil, each sample was heated to a temperature of 6870C in an IRenergized installation. Humidity of samples was (6,0 0,2). Extraction of oil from melon seeds is carried out in bench conditions on the screw press DUO (Farmet a.s., Czech Republic) at the set optimal parameters of the screw press: shaft speed of 40 rpm the diameter of the outlet of the removable nozzle 6 mm the gap between the base of the screw and the pressing head 3 mm. It was found that when the fruit shell is reduced to 8 in the sound fraction, the yield of melon oil increases to 37, the content of crude protein in the cake increases to 56 and the oil content of the obtained cake decreases to 9. This improves the quality of melon oil. According to the results of studies of the equation for calculating the yield of melon oil, crude protein content and oil content of oil cake, depending on the content of the fruit shell in the sound fraction of melon seeds obtained. These equations can be used for operational control of technological process and forecasting of indicators of quality of the received production.

Current geopolitical and economic conditions for the functioning of railway transport in most post-Soviet states are such that it is extremely difficult to provide required quality of transport services and break-even operations at high expenses for maintaining the railway infrastructure and rolling stock. Dynamics of transportation of the Tajik Railway (TSR) is shown, which displays that most of its sections are classified as low-intensity ones. The paper proposes methodical principles, setting and qualitative analysis of the task of rationalization of operational work and organization of car flows for international transportation, taking into account the specifics of the Tajik Railway. There is a problem of complex maintenance of the efficiency of operational work in modern conditions based on the synthesis of the tasks of self-management (rational internal operational technology of the Tajik Railway) and coordination tasks (technological interaction with railway administrations of other states). Author substantiated the necessity of solving this problem. Proposed classification of technological restrictions and controlled variables in the performance of transport takes into account methods for changing external conditions for the functioning of the railway landfill and methods for increasing internal efficiency of its operation. The search for the solution of the problem involves direct search of variants along its ordered set with clipping of groups of variants that do not correspond to constraints, with the subsequent finding of compromise control over a set of effective alternatives.

AbstractX oilfield is a typical sandstone reservoir with big bottom water in the Bohai Sea. The viscosity of crude oil ranges from 30 to 425 cp. Single sand development with the horizontal well is adopted. At present, the water content is as high as 96%. The water cut of the production well is stable for a long time in the high water cut period. The recoverable reserves calculated by conventional methods have gradually increased, and even the partial recovery has exceeded the predicted recovery rate. This study carried out an oil displacement efficiency experiment under big water drive multiple to accurately understand an extensive bottom water reservoir's production law in an ultra-high water cut stage. It comprehensively used the scanning electron microscope date, casting thin section, oil displacement experiment, and production performance to analyze the change law of physical properties and relative permeability curve from the aspects of reservoir clay minerals, median particle size, pore distribution, and pore throat characteristics. Therefore, the development law of horizontal production wells in sandstone reservoirs with big bottom water is understood. It evaluates the ultimate recovery of sandstone reservoirs with big bottom water. It provides a fundamental theoretical basis and guidance for dynamic prediction and delicate potential tapping of sandstone reservoirs with big bottom water at a high water cut stage.
