| 17 | Bridging performance of new eco-friendly lost circulation materials显示文摘Lost circulation is one of the most important concerns of the drilling industry, causing excessive expenditure and increasing the non-productive drilling time. In this study, various lost circulation materials(LCMs) were used to control the lost circulation of two types of drilling fluids, bentonite mud and a new eco-friendly mud, named RIA-X, which has a remarkable effect on decreasing the amount of lost circulation in fractured and highly permeable reservoirs. The Bridging Material Test(BMT) apparatus was used to investigate the effectiveness of various LCMs in fractures of various sizes and to select the LCM and combination with the best performance. The use of three-dimensional fractures is one of the most notable points of this work, which makes the experimental conditions similar to those of real wells. The lost control performance of the new eco-friendly LCMs in RIA-X mud was tested in field. The outcomes show that the designed LCMs are able to control severe lost circulation that regular processes such as cementing or drilling with foam cannot deal with. | NASIRI Alireza GHAFFARKHAH Ahmadreza DIJVEJIN Zahra Azimi MOSTOFI Masood MORAVEJI Mostafa Keshavarz | 2018 | Petroleum Exploration and Development2018，45，6： | 0 |
| 18 | 油性微乳液的循环气升式反应器的流体力学和传质性能研究(英文)显示文摘This study reports an experimental investigation on hydrodynamics and mass transfer characteristics in a 15.6×10?3 m3 external loop airlift reactor for oil-in-water micro-emulsions with oil to water volume ratio(φ) ranging from 3% to 7%(by volume). For comparative purposes, experiments were also carried out with water. Increase in φ of micro-emulsion systems results in an increment in the gas holdup and a decrease in the volumetric gas-liquid oxygen transfer coefficient and liquid circulation velocity, attributed to the escalation in the viscosity of micro-emulsions. The gas holdup and volumetric mass transfer coefficient for micro-emulsion systems are significantly higher than that of water system. Two correlations are developed to predict the gas holdup and oxygen trans-fer coefficient. | Mona Ebrahimi Fakhari Mostafa Keshavarz Moraveji Reza Davarnejad | 2014 | Chinese Journal of Chemical Engineering2014，22，3： | 0 |
| 19 | Investigation of bubble diameter and flow regime between water and dilute aqueous ethanol solutions in an airlift reactor显示文摘In this study,the effect of ethanol addition into pure water and its concentration on bubble diameter,gas hold-up andflow regimes were investigated in an airlift reactor.Air and water with ethanol(concentration ranging from 0%–1%,v/v)were as dispersed and continuous phases,respectively.Superficial gas velocity was consid-ered as an effective parameter.Bubble size distribution was measured by photography and picture analysis at various concentrations of ethanol and various velocities of gas.Alcohol concentration enhancement caused bubble dia-meter to decrease.Furthermore,the bubbles diameter in pure water was nearly 4 times higher than that of ethanol with concentration of 1%(v/v)and also was 3.4 times higher than that of ethanol with concentration of 0.25%(v/v)at the highest aeration gas velocity inlet.For ethanol solutions in lower superficial gas velocity,a homogenousflow regime was observed.This trend continued to inlet gas velocity of about 0.4 cm/s.The transitionflow regime occurred after this datum although in pure water,a homogenousflow regime was observed up to a superficial gas velocity of 0.7 cm/s.The gas hold-up in dilute ethanol solutions were more than(around 2 times)that of pure water and increased with increasing concentration of ethanol in those solutions. | Baharak SAJJADI Mostafa Keshavarz MORAVEJI Reza DAVARNEJAD | 2011 | Frontiers of Chemical Science and Engineering2011，5，2： | 0 |
| 20 | CFD simulation of the hydrodynamics in an internal air-lift reactor with two different configurations显示文摘Computationalfluid dynamics(CFD)was used to investigate the hydrodynamic parameters of two internal airlift bioreactors with different configurations.Both had a riser diameter of 0.1 m.The model was used to predict the effect of the reactor geometry on the reactor hydrody-namics.Water was utilized as the continuous phase and air in the form of bubbles was applied as the dispersed phase.A two-phaseflow model provided by the bubblyflow application mode was employed in this project.In the liquid phase,the turbulence can be described using the k-εmodel.Simulated gas holdup and liquid circulation velocity results were compared with experimental data.The predictions of the simulation are in good agreement with the experimental data. | Mona EBRAHIMIFAKHAR Elmira MOHSENZADEH Sadegh MORADI Mostafa MORAVEJI Mahmoud SALIMI | 2011 | Frontiers of Chemical Science and Engineering2011，5，4： | 0 |
