But the influx of dollars created upward pressure on the exchange rate of the Vietnamese dong, which could have hurt exports. 但是,美元进入越南给越南盾汇率的上升造成压力,越南盾的汇率上升将影响越南的出口贸易。
However, it is not practical and not precise to calculate the dimensionless water influx rate by available table-lookup method. 通常无因次水侵量的计算采用查表的方法,既不实用,精度又低。
The influences of oxygen impurity influx rate and confinement time on intensity and switch-on time of line emissions are surveyed numerically. 用数值计算分别考察了氧杂质进入通量和约束时间对谱线峰值强度和起始时间的影响。
Both here and abroad there are many scholars toward water invasion question who have processed a lot of foundational work, they supposed clearly assorted water invasion models, and deduced some kinds water influx rate calculation method. 国内外不少学者对于水侵问题进行了大量的基础性研究工作,假设了各种各样的水侵模型,并且推导出若干种水侵量计算方法。
A New Method for Calculating Dimensionless Water Influx Rate 无因次水侵量计算新方法
The calculation of dimensionless water influx rate has to be made for both reserves estimation and performance prediction in process of development of natural water drive reservoirs. 天然水驱油气藏的开发过程中,无论储量计算还是动态预测,都离不开无因次水侵量的计算。
Optimized Method for Calculating Water Influx Rate of Reservoir with Edge and Bottom Water 边底水油藏水侵量计算最优化方法
Key problems, such as the disposal of produced sand and the estimation of critical pressure differential and sand influx, sand delivery and equipments corrosion rate, and so on, are discussed. 讨论了海上油田应用适度出砂技术应解决的关键问题,包括砂子产出后的处理问题、临界压差和出砂量预测问题、砂子输送预测问题、以及设备侵蚀率预测问题等。
