| 1 | 采用海泡石纳米颗粒控制膨润土基钻井液性能显示文摘提出在膨润土基钻井液中添加海泡石纳米颗粒来控制其性能,并通过实验研究了不同温度压力条件下海泡石纳米颗粒对膨润土基钻井液流变性、滤失性等性能的影响。测量了添加海泡石纳米颗粒前后膨润土基钻井液在不同温度压力条件下的塑性黏度、动切力和滤失量,并在储集层温度压力条件下对添加海泡石纳米颗粒前后的膨润土基钻井液进行了岩心驱替实验,对比了钻井液的滤失量及对地层的伤害程度。结果表明:添加海泡石纳米颗粒可以提高清水和盐水膨润土基钻井液的塑性黏度和动切力;海泡石纳米颗粒可以在较大的温度和压力范围内特别是高温高压条件下保持钻井液流变性的稳定;储集层温度压力条件下,海泡石纳米颗粒降低了钻井液的滤失量,抑制了砂岩岩心渗透率降低。海泡石纳米颗粒是一种理想的膨润土基钻井液添加剂。 | AL-MALKI Needaa POURAFSHARY Peyman AL-HADRAMI Hamoud ABDO Jamil | 2016 | 石油勘探与开发2016，43，4： | 7 |
| 2 | Nitrogen Deep Placement Combined with Straw Mulch Cultivation Enhances Physiological Traits,Grain Yield and Nitrogen Use Efficiency in Mechanical Pot-Seedling Transplanting Rice显示文摘To assess the effects of straw return coupled with deep nitrogen(N)fertilization on grain yield and N use efficiency(NUE)in mechanical pot-seedling transplanting(MPST)rice,the seedlings of two rice cultivars,i.e.,Yuxiangyouzhan and Wufengyou 615 transplanted by MPST were applied with N fertilizer at 150 kg/hm2 and straw return at 6 t/hm2 in early seasons of 2019 and 2020.The experiment comprised of following treatments:CK(no fertilizer and no straw return),MDS(deep N fertilization and straw return),MBS(broadcasting fertilizer and straw return),MD(deep N fertilization without straw return),MB(broadcasting fertilizer without straw return).Results depicted that the MDS treatment significantly increased the rice yield by 41.69%-72.22%due to total above-ground biomass,leaf area index and photosynthesis increased by 54.70%-55.80%,38.52%-52.17%and 17.89%-28.40%,respectively,compared to the MB treatment.In addition,the MDS treatment enhanced the total N accumulation by 37.74%-43.69%,N recovery efficiency by 141.45%-164.65%,N agronomic efficiency by 121.76%-134.19%,nitrate reductase by 46.46%-60.86%and glutamine synthetase by 23.56%-31.02%,compared to the MB treatment.The average grain yield and NUE in both years for Yuxiangyouzhan were higher in the MDS treatment than in the MD treatment.Hence,deep N fertilization combined with straw return can be an innovative technique with improved grain yield and NUE in MPST in South China. | LI Lin ZHANG Zheng TIAN Hua Umair ASHRAF Yousef Alhaj HAMOUD Al Aasmi ALAA TANG Xiangru DUAN Meiyang WANG Zaiman PAN Shenggang | 2022 | Rice science2022，29，1： | 5 |
| 3 | Effects of irrigation water regime, soil clay content and their combination on growth,yield,and water use efficiency of rice grown in South China显示文摘To investigate the effect of irrigation regime,soil clay content and their combination on growth,yield,and water productivity of rice,a shelter experiment was conduct using Randomized Complete Block Design(RCBD)with a factorial arrangement of treatments with four replications.Irrigation regime was the main treatment investigated,set in three levels as R(30 mm-100%)(100%of saturation and 30 mm flooded),R(30 mm-90%)(90%of saturation and 30 mm flooded)and R(30 mm-70%)(70%saturation and 30 mm flooded),respectively.The sub-treatment was soil type,set in three levels as 40%,50%and 60%clay content,respectively.Results showed that irrigation regime and soil clay content had significant effects on growth,yield and water productivity of rice.However,their combination showed no significant impact on panicles number,root biomass,harvest index and irrigation water productivity.Higher soil clay content results in increase in growth,yield,and water productivity of rice.The total water consumption during R(30 mm-100%)was higher than that during R(30 mm-90%)and R(30 mm-70%)because the latter two saturation levels led to the cracking of soil and decrease of total number of irrigations.Cracks were consistently getting more serious with the reduction in soil water content and the increase in soil clay content.Cracks in soil will preferentially become the major routes of water losses,thus water percolation during R(30 mm-70%)was higher than that during R(30 mm-90%)and R(30 mm-100%)after each irrigation event.The total water use under R(30 mm-70%)exceeded the water consumption under R(30 mm-90%)due to the great amount of soil cracking as well as the excessive volume of standing water depth.Considering water consumption and grain yield,the following conclusion can be reached:(i)The reduction in water consumption was greater than the reduction in grain yield in the case of drying soil 10%below saturation before reflooding.(ii)The reduction in water consumption was less than the reduction in grain yield in the case of drying soil 30%below saturation before reflooding;(iii)The increase in water use was greater than the increase in grain yield in the case of maintaining soil moisture at 100%of saturation before reflooding.Therefore,the water use efficiency was recorded in the order of R(30 mm-90%)>R(30 mm-100%)>R(30 mm-70%). | Yousef Alhaj Hamoud Xiangping Guo Zhenchang Wang Sheng Chen Ghulam Rasool | 2018 | International Journal of Agricultural and Biological Engineering2018，11，4： | 3 |
| 4 | Injection of biosurfactant and chemical surfactant following hot water injection to enhance heavy oil recovery显示文摘This study investigates the potential of enhancing oil recovery from a Middle East heavy oil field via hot water injection followed by injection of a chemical surfactant and/or a biosurfactant produced by a Bacillus subtilis strain which was isolated from oil-contaminated soil.The results reveal that the biosurfactant and the chemical surfactant reduced the residual oil saturation after a hot water flood.Moreover,it was found that the performance of the biosurfactant increased by mixing it with the chemical surfactant.It is expected that the structure of the biosurfactant used in this study was changed when mixed with the chemical surfactant as a probable synergetic effect of biosurfactant-chemical surfactants was observed on enhancing oil recovery,when used as a mixture,rather than alone.This work proved that it is more feasible to inject the biosurfactant as a blend with the chemical surfactant,at the tertiary recovery stage.This might be attributed to the fact that in the secondary mode,improvement of the macroscopic sweep efficiency is important,whereas in the tertiary recovery mode,the microscopic sweep efficiency matters mainly and it is improved by the biosurfactantchemical surfactant mixture.Also as evidenced by this study,the biosurfactant worked better than the chemical surfactant in reducing the residual heavy oil saturation after a hot water flood. | Yahya Al-Wahaibi Hamoud Al-Hadrami Saif Al-Bahry Abdulkadir Elshafie Ali Al-Bemani Sanket Joshi | 2016 | Petroleum Science2016，13，1： | 2 |
| 5 | 用甲醇处理凝析气藏凝析堵塞的现场应用显示文摘通过现场试验研究了用甲醇解除近井带凝析油堵塞的有效性。所做的Texas乳状石灰岩及Berea岩心驱替实验表明 ,凝析油积聚 (尤其是当含水饱和度较高时 )会严重降低气相相对渗透率。当井底压力降至露点压力以下时 ,产能下降到原来的 ~ 。对Alabama地区的Hatter’sPond油田气样所做的PVT分析表明它具有反凝析特性。这些高温深气井的表皮系数很大 ,产气量低。对资料的初步分析表明 ,这可能是由于凝析油堵塞和水基泥浆滤失引起的水堵塞造成的。通过配伍性试验 ,确保了注入的滤液和甲醇不会对岩心造成任何伤害。由于储层中盐水含量很高 ,因此需在注甲醇前进行盐析校核试验。基于这些实验结果及对 1口井进行数值模拟后做了现场试验。试验前 ,试验井气产量为 2 5 10 4(标准 )ft3/d ,凝析油产量为 87bbl/d。以每分钟 5~ 8bbl的速度向油管内泵入 10 0 0bbl甲醇进行处理后 ,开始时日产气量增加了 3倍 ,随后产量保持在 5 0〔10 4 (标准 )ft3/d左右 ,而凝析油产量增加到 15 7bbl/d。经甲醇处理后 ,表皮系数降低到 - 1 9,油气增产有效期在 10个月以上。 | Hamoud A Al-Anazi 肖曾利 冯金德 蒲春生 | 2004 | 国外油田工程2004，20，5： | 2 |
