1)  reperforation
二次射孔
1.
This useful acknowledgement provides some importance to the reperforations.
油田采用聚驱开发时 ,由于原水驱时主力油层含水较高 ,为了在注聚合物前的空白水驱阶段提高生产经济效益 ,对高含水主力油层的聚合物油井在完井时不射开 ,而在注聚合物之后再补孔 ,即进行二次射孔开发。
2)  secondary mesopore
二次介孔
1.
Advances in preparation and application of zeolites with secondary mesopores;
具有二次介孔分子筛材料的制备和应用
3)  Secondary blowhole
二次气孔
4)  Mesopore
二次孔
1.
Study on the Formation of Mesopore during Hydrothermal Dealumination of Y Zeolite;
水热处理USY二次孔形成规律研究
2.
The results show that addition of acid treatment process after the Y zeolites modified procedure can increase the surface area,mesopore volume,and optimize acid sites of th.
氮吸附、XRD、TEM和吡啶吸附-脱附红外光谱法等表征结果表明,酸处理可以有效脱除分子筛中的非骨架铝,增加改性Y沸石的比表面积和二次孔的孔容,并起到优化酸中心的目的。
5)  Secondary pore
二次孔
1.
The result showed that the USY rich in secondary pores or mesopores can be prepared by chemical hydrothermal treatment of NaY under certain conditions, and the secondary pore distribution can be flexibly adjusted to meet the application demand.
采用全自动吸附仪考察了化学超稳分子筛的孔结构,结果表明,NaY分子筛经一定条件改性处理后,可以制得具有发达二次孔结构的超稳分子筛,并且其二次孔分布可以灵活调整,满足不同需要;考察结果还表明:化学脱铝是分子筛造孔的必要条件,水热处理是分子筛造孔的关键步骤。
2.
The results indicate that NHSY has following properties:(1) the aluminum distribution is more homogeneous than USY prepared by hydrothermal treatment and FSEY prepared by treatment with (NH4),SiF6;(2) the framework aluminum defect sites are less than USY and FSEY; (3) the nonframework aluminum content is properly low;(4) the secondary pore system is very developed.
结果表明,NHSY具有Al分布均匀、骨架Al空位少、含非骨架Al少而适量和二次孔体系发达等显著特点。
6)  Secondary Channel
二次孔道
1.
Laboratory Experimental Studies on Optimal Time and Site Selection for Plugging Secondary Channel in Waterflooding Reservoirs;
注水开发油田二次孔道最佳封堵时机和最佳封堵位置的室内实验研究
补充资料:惜别行送刘仆射判官(仆射乃其主将刘乃仆射
【诗文】:
闻道南行市骏马,不限匹数军中须。襄阳幕府天下异,
主将俭省忧艰虞。只收壮健胜铁甲,岂因格斗求龙驹。
而今西北自反胡,骐驎荡尽一匹无。龙媒真种在帝都,
子孙永落西南隅。向非戎事备征伐,君肯辛苦越江湖。
江湖凡马多憔悴,衣冠往往乘蹇驴。梁公富贵于身疏,
号令明白人安居。俸钱时散士子尽,府库不为骄豪虚。
以兹报主寸心赤,气却西戎回北狄。罗网群马籍马多,
气在驱驰出金帛。刘侯奉使光推择,滔滔才略沧溟窄。
杜陵老翁秋系船,扶病相识长沙驿。强梳白发提胡卢,
手把菊花路旁摘。九州兵革浩茫茫,三叹聚散临重阳。
当杯对客忍流涕,君不觉老夫神内伤。
