  decline
With increasing the amount of salt, there was hardly influence on the growth rate along c-axis, whereas an obvious decline was observed in the growth rate along either a-axis or b-axis, which enlarges the boundaries between the surface crystals.
      
Results show that the coefficient of variation (Cv) of throughfall tends to decline as rain intensity increases.
      
The biomass ratio of the slow growth group trees tended to increase and the fast-medium group trees tended to decrease as the community developed, which was reveresed in the decline development stage.
      
However, as the level of burial increases, the positive response starts to decline until it becomes a negative value.
      
The elevated concentration of atmospheric CO2 may result in a decline of leaf nutritional quality (especially N) and an increase in some kinds of defensive secondary components (such as phenolics).

On the basis of the differential equation for decline of production by Arps, J.J., the paper derived the exponent decline, harmonic decline and hyperbolic decline. Conditions causing the harmonic decline to occur and the factors affecting the initial decline rate are proved theoretically. The constants in the equation are simply determined by means of plotting, thus, making this method described in the paper more applicable to the field.

本文从Arps,J.J.的产量递减率微分方程出发,严格推导了产量递减的三种基本规律,即指数递减、调和递减和双曲线递减.从理论上证明了产生调和递减的条件以及影响初始递减率的因素,并用图版法简便地确定了计算公式中的常数项,使本方法更便于在矿场中推广应用.文中还用大量的实际资料检验了应用产量递减曲线预测油田开发动态指标的准确性,并对油田已出现综合递减的区块进行了预测.

本文从水驱孔隙性砂岩油田开发的基本理论出发,在分析大庆油田实际资料的基础上,采用数理统计方法,找出采油指数、井底流压、含水上升率随含水率变化的数学表达式。通过其相互关系的研究,给出在油田稳产期内,预测产油量自然递减的经验方法。经实际资料检验,此方法预测产量的相对误差最大不超过10%。

The YL oil field is a carbonate reservoir with double porosity under bottom water drive, The initial reservoir pressure is 308 atm, and saturation(bubble point) pressure is 14 atm. Active bottom water drive has been observed at early stage of development This paper, based on the practical field data gives some methods of reservoir behavior analysis to be used in its declining period. These methods can be used to predict the performance of similar oil reservoirs and predicting recovery efficiency of the YL oil field is fairly low and will be less than 25% of the initial oil in place of the volumetrieal method.

YL油田是一个双重孔隙介质、底水驱动的灰岩油藏。原始地层压力为308大气压,饱和压力为14大气压,而在开发初期表现出了活跃的天然底水驱动作用。本文基于YL油田产能递减阶段的实际开发数据,提供了一些开发动态的分析方法。这些方法可以用于预测同类油田的开发动态,也可用于估算在废弃条件下的最终采收率。YL油田的最终采收率不高,而将不会超过原始地质储量的25%。
