| 1 | Emergence of nanotechnology in the oil and gas industry:Emphasis on the application of silica nanoparticles显示文摘The application of nanotechnology in the oil and gas industry is on the rise as evidenced by the number of researches undertaken in the past few years.The quest to develop more game-changing technologies that can address the challenges currently facing the industry has spurred this growth.Several nanoparticles,of different sizes and at different concentrations,have been used in many investigations.In this work,the scope of the study covered the application of nanotechnology in drilling and hydraulic fracturing fluids,oilwell cementing,enhanced oil recovery(which includes transport study,and foam and emulsion stability),corrosion inhibition,logging operations,formation fines control during production,heavy oil viscosity reduction,hydrocarbon detection,methane release from gas hydrates,and drag reduction in porous media.The observed challenges associated with the use of nanoparticles are their stability in a liquid medium and transportability in reservoir rocks.The addition of viscosifier was implemented by researchers to ensure stability,and also,surface-treated nanoparticles have been used to facilitate stability and transportability.For the purpose of achieving better performance or new application,studies on synergistic effects are suggested for investigation in future nanotechnology research.The resulting technology from the synergistic studies may reinforce the current and future nanotechnology applications in the oil and gas industry,especially for high pressure and high temperature(HPHT)applications.To date,majority of the oil and gas industry nanotechnology publications are reports of laboratory experimental work;therefore,more field trials are recommended for further advancement of nanotechnology in this industry.Usually,nanoparticles are expensive;so,it will be cost beneficial to use the lowest nanoparticles concentration possible while still achieving an acceptable level of a desired performance.Hence,optimization studies are also recommended for examination in future nanotechnology research. | Muili Feyisitan Fakoya Subhash Nandlal Shah | 2017 | Petroleum2017，3，4： | 10 |
| 2 | 空心杆泵上循环热水加热降粘的数值研究显示文摘稠油开采过程中,准确预测井筒温度及原油的粘度变化对选择合适的采油工艺具有指导意义。运用计算流体力学(Computational fluid dynamics,CFD)数值模拟方法,建立空心杆泵上循环热水加热降粘数值模型,进行数值求解,得出循环热水及原油沿程温度和粘度变化规律,并建立目标函数研究平均降粘及减阻效果。结果表明,根据循环热水进口温度的不同,原油在距离进口30~35 m附近温度达到峰值,随后温度呈降低趋势;循环热水入口温度为分别为80℃、70℃和60℃时,原油全管程的降粘率分别为97.3%、96.7%和94.6%。 | 史维秀 李惟毅 潘利生 谈西峰 | 2011 | 机械工程学报2011，47，2： | 4 |
| 3 | 过热蒸汽改善驱油效果实验及机理分析显示文摘为探究注过热蒸汽对驱油效果的改善情况,通过室内单管驱替实验,研究蒸汽质量、注汽速率对采收率的影响,并从黏度、渗透率、热膨胀系数和蒸馏率4个方面对驱油机理进行分析。结果表明,当注汽速率为1.8mL/min时,最优注入蒸汽质量为注过热15℃蒸汽,最终采收率可达77.8%;按照最优注入蒸汽质量注汽,最优注汽速率为1.3mL/min,最终采收率可达79.6%;过热蒸汽驱替后,50℃原油黏度减小40.7%;实验用油平均热膨胀系数为0.000653℃^-1,原油温度增加300℃,体积增加19.6%;过热蒸汽促使蒙脱石和高岭石向绿泥石或伊利石发生转化,物理冲刷会使孔隙通道增大,改善储集层渗流状况。 | 郭彬 林日亿 王泽宇 马强 王新伟 | 2019 | 新疆石油地质2019，40，4： | 3 |
| 4 | 空心抽油杆热水循环降黏效果影响因素显示文摘在高凝油油田开发过程中,采用空心抽油杆热水循环工艺的伴热方式可有效提高油田稠油开采效率。针对空心抽油杆热水循环加热工艺,通过流体流动特性和地层物质间传热特性建立数学模型,利用多物理场耦合的有限元计算方法,选取含水率、连续管内径和注入水工作参数,以平均降黏率为衡量指标,对该工艺的降黏效果进行研究。结果表明:计算结果与现场实测数据的误差小于5%,可靠性高;该工艺在含水率相对较低的油井中具有更好的降黏效果,采用较细连续管可有效提高工艺降黏效率;与增加注水量相比,增加注水温度具有更佳的技术经济效果。 | 王小兵 刘阳 李森 李景波 吕雷纲 龚浩宇 王多琦 杜明智 | 2020 | 大庆石油地质与开发2020，39，4： | 1 |
| 5 | 超稠油氧化催化剂的制备及性能显示文摘以金属Ni、Cu、Fe的硫酸盐分别和乙酰丙酮为原料合成了3种金属盐催化剂CT1、CT2和CT3,CT1和CT2催化剂在330℃均具有很好的热稳定性。考察了在地层温度150℃下含水量、空气压力以及反应时间对稠油氧化后的酸值、吸氧量、族组成和黏度的影响。实验结果表明:氧化催化反应产物的饱和分增加、胶质降低。提高空气压力、延长反应时间以及降低含水率有助于催化氧化过程中酸性物质的生成和氧气的消耗,含水率降低容易导致稠油过度氧化而缩合生成沥青质,进而形成焦炭。CT1的催化降黏效果优于CT2和CT3。CT1注空气催化氧化稠油的适宜反应条件为:油水质量比7/3,反应压力1.0MPa,反应时间24~36h,在此条件下稠油降黏率大于76%。 | 贾霖 邓科 郑延成 吴川 连响 郝栩麟 田雨 | 2019 | 精细石油化工2019，36，4： | 0 |
