Rheological properties of polymer solutions and ways to improve the efficiency of development of high-viscosity oil fields in Uzbekistan

The results of experimental research on studying the filtration properties of polymer solutions and the mechanism of the displacement process in porous medium were presented in this article. The methodology of experimental studies in a specially designed laboratory setup is given. In the present work the rheological properties of polymer K-9 are considered. At the same time, the relaxation time of viscoelastic particles of K-9 polymer filtered in porous medium is experimentally found. Also, the results of experimental studies on oil displacement of fields with high content of asphaltene-resinous substances by polymer solutions on artificially created reservoir models to determine the optimal concentration of polymer solution and the size of the rim with the purpose of increasing oil recovery. Experimental studies on displacement of high-viscosity oils with a thickened water rim established that this method gives the greatest increase in water-free and ultimate oil recovery of reservoirs, within the range of change in the concentration of polymer solution 0.2-0.4%, with the size of the rim more than 70% of the oil saturated volume of the reservoir. Studies on displacement of high-viscosity oils by polymer solutions show that the use of this method of increasing oil recovery factor in practice is not always economically feasible, because of the need to ensure high injection pressures and high concentration of expensive polymer solution

Факторы развития острого почечного повреждения при острых инфекционных диареях, протекающих с гемоколитом, у детей

Outcomes of severe variants of acute infectious diarrhea in children with acute renal injury/failure (ARI/ARF) remain unsatisfactory, and mortality reaches 70% and more. ARI/ ARF therapy requires high material costs, which represent significant burden on health financing systems. It makes us consider AFR as one of the most important medical and social problems.The aim of our study was to investigate predisposing factors contributing to the development of renal dysfunction in acute infectious diarrhea associated with hemocolitis (AIDH), as well as to study the relationship of the developed renal dysfunction with the severity of endogenous intoxication, damage of vascular endothelium and hemostasis system.We examined 60 sick children with AIDH, divided into two groups: with ARF and without kidney pathology.Susceptibility to ARI/ARF in severe forms of AIDH is mediated by early childhood (up to 3 years in 89,5% of patients), artificial and mixed feeding (in 52,6% and 36,8% of children respectively), pathology of pregnancy in the first trimester, mother diseases during pregnancy (84,2%) and the late admission to hospital (89,5%) on the 4,9±0,2 day of the disease, i/m administration of furosemide without volume circulating blood restoration, i/m administration of nephrotoxic antibacterial medicines. Shigella spp. and Escherichia coli as etiologic factors of diarrhea in 42,1% and 47,4% of cases respectively. Thus due these parameters we can predict the loss of kidneys adaptation ability in diseases with severe course including acute infectious diarrheas.Interrelationships between elevation of the number of antigen binding lymphocytes to tissue antigens of vascular endothelium up to 8,1±0,6% in children with ARF and development of hemorrhagic syndrome (decrease of PTI to 72,5%) and intensity of endogenic intoxication (average molecular peptides up to 9,7±0,6 g/l) and worsening of AFR signs were established.Thus, it was found that AKI most often develops when rehydration therapy is started late or inferiorly performed, when nephrotoxic antibiotics and loop diuretics are prescribed without circulating blood volume (CBV) compensation and is accompanied by an increase in the degree of endogenous intoxication and vascular endothelial damage. Исходы тяжелых вариантов острых инфекционных диарей у детей с острым почечным повреждением/недостаточностью остаются неудовлетворительными, а летальность достигает 70% и более. Терапия острого почечного повреждения/острой почечной недостаточности требует больших затрат, которые ложатся тяжелым бременем на систему финансирования здравоохранения. Все это заставляет рассматривать острую почечную недостаточность в качестве одной из важнейших медико-социальных проблем.Цель: изучение факторов, способствующих развитию дисфункции почек при острых инфекционных диареях, протекающих с гемоколитом, и взаимосвязи развившейся острой почечной недостаточности с выраженностью эндогенной интоксикации, поражением эндотелия сосудов и состоянием системы гемостаза.Обследовано 60 детей с острыми инфекционными диареями, протекающими с гемоколитом, разделенных на две группы: с и без острого почечного повреждения/ острой почечной недостаточности. Формированию предрасположенности к развитию ОПП/ОПН при тяжелой форме ОИДСГ у детей явился более ранний возраст (до 3 лет – 89,5%), искусственный и смешанный вид вскармливания(52,6%/36,8%), патология беременности, заболевания матери в первом триместре беременности (84,2%) и поздний срок поступления в стационар (89,5% поступили на 4,9±0,2 день заболевания), внутримышечное введение фуросемида без восстановления объема циркулирующей крови, введение внутримышечно нефротоксичных антибактериальных средств, этиологический фактор диареи (шигеллы в 42,1% и диареегенные эшерихии в 47,4% случаев). Основываясь на этих показателях, мы сможем прогнозировать утрату адаптационной способности почек при различных заболеваниях с тяжелым течением, включая острые инфекционные диареи.Отмечена взаимосвязь между повышением уровня антигенсвязывающих лимфоцитов к тканевым антигенам эндотелия сосудов до 8,1±0,5% у больных детей с ОПП/ОПН и развитием геморрагического синдрома (снижение ПТИ до 72,6±0,9%) с выраженностью степени эндогенной интоксикации (повышением уровня среднемолекулярных пептидов до 9,7±0,3 г/л) и усугублением признаков острого почечного повреждения.

Oral anticoagulation in end-stage CKD and atrial fibrillation

Leading cardiovascular diseases (arterial hypertension, coronary heart disease and diabetes mellitus) are often accompanied by such complications as atrial fibrillation (AF) and chronic kidney disease (CKD). As kidney function worsens, the risk of AF increases. The incidence of AF and CKD ranges from 5:1. At the same time, the risk of developing of end-stage CKD (ESCKD) increases in patients with AF. The combination of AF and ESCKD, on the one hand, increases the risk of thromboembolic complications, and on the other hand, it can cause hemorrhagic complications, which makes it difficult to decide whether to start oral anticoagulant therapy

Experimental study of the features of filtration of non-Newtonian oils in a porous medium

The current state of development of deposits with high-viscosity oils is characterized by a low value of the achieved oil recovery with a high water cut in the produced wells. However, ways to improve the implemented development systems in order to increase the recovery factor in conditions of high water cut in well production, especially in the late stage of operation requires further research. Therefore, this research intended to investigate features of filtration of non-Newtonian oils in a porous medium. Oil fields with a complex geological structure have been discovered in many oil and gas regions of the world. These fields are characterized by a small oil-saturated thickness of the reservoirs, low reservoir properties, high viscosity of reservoir oil and heterogeneity of productive horizons. To study the filtration process, a specially designed installation was used. Clearly, the main elements are a column (core holder) with a water jacket, an oil tank, a thermostat and a high-pressure air tank (compressor). A research experiment was undertaken in two oil fields, which are X and Y. The results of physicochemical properties of oil field X showed that the density was 0.878g/cm3, followed by sulfur content (1.51%), pitches (21.89), asphaltenes was 4.19, and paraffin was 5.18
