摘要
在分析单相流动与多相流动速度剖面校正因子差异的基础上,本文提出了一种利用地面油气水产量和生产测井参数确定涡轮流量计速度剖面校正因子的新方法,这种方法通过流体物性参数计算对地面产量进行井下刻度,得出一个不受井与井差异影响的流量计速度剖面校正因子,在各解释层流型没有显著差异的情况下。可以把该校正因子推广到整个产层进行产量计算。
Based on the analysis of different velocity profile correction factors (VPCF) for single-phase and multiphase flow, this paper presents a new method for determining VPCF of spinner flowmeter with production log parameters, and oil, gas and water production rates. That is to obtain VPCF, which is independent of different well conditions, by computing the fluid physical parameters and converting the output into reserves under downhole condition. If flow parameters have no obvious difference between the analysed zones, VPCF from this method can be used for the entire pay zone to calculate production rate. Example is presented in this paper.
