Practice for determining a flow - proportioned average property value for a collected batch of process stream material using stream analyzer data 利用流量分析数据测定加工流动材料集积批平均流动特性值的惯例
Note : ? for intermediate valve positions the flow coefficient table can be used to determine actual flow between graph positions 注意: - -对于中间阀位置,可以利用流量系数表来决定曲线图位置之间的实际流量。
According to the practical situation of production logging in fields , simplification of the functions are introduced so that the basic mathematical model of the oil / water two - phase profile interpretation based on temperature and flowmeter logs as well as its characteristics has been presented 根据现场生产测井实际隋况,对该方程组进行了简化求解,从而提出了利用流量、温度信息确定油水两相产出剖面的基本数学模型,并对模型的数学特点进行了分析。
Because the supply water system is large - scale , the pump stations are many , the ways of supply water are complicated , and the adjustable spare is large , the whole data in the optimization of supply water , the flux and its variety regulations in the control stations ca n ' t be acquired . the paper predicts supply water during the process based on the theory of artificial neural network control . the optimization has two steps 在实际供水系统中很难准确地获取整个管网的所有基础数据,主要难以预知所有节点的逐时流量及其变化规律,因此成为供水系统的优化调度的难点,本文采用人工神经网络对供水量进行预测,应用二级优化调度,第一级以整个供水系统的费用最小为目标,用回归方法求出各供水节点的供水量;第二级利用流量跟踪的方法对每个供水节点(泵站)实现优化运行,以期在泵站内达到最大节能目的。
According to the basic mathematical model of the oil / water two - phase profile interpretation based on temperature and flowmeter logs , a similar idea to that of " first getting the retrieve function then the original function " is employed to solve the model . the recursive arithmetic suitable to computer programming has been presented , which make the profile technique available in practical production 本文根据利用流量、温度信息确定油水两相产出剖面的基本数学模型,提出了一种类似于函数论中常常用到的一种求形式复杂函数的办法对模型进行了求解,从这一思想出发,给出了适合计算机程序实现的递推求解算法,并且编制程序对算法进行了实现。
