摘　　要：传统方法是直接将持水率值测量后未经校正就用于科学计算,这样存在着较大误差。经过持水率仪器实验和测试分析研究一套持水率校正算法,并用计算机软件实现,能降低生产测井解释含水率误差,准确的计算出油气水各相产出层的含水率值,提高了生产测井找水精度。通过实验图版研究出油气两相持水率校正图版和气液两相持水率校正图版,采取分段拟合的思想,推算出持水率校正公式。通过软件实现,达到了精确计算持水率值的目的,经测试得知校正后的持水率值推算出来的含水率误差与生产实测误差最大为6.42%。There are big errors with the traditional method which is direct to use the measurement water holding rate value without correction for scientific computing.With water holding rate Instrument experiment 、testing analysis and with the computer software to realize,one water holding rate correction algorithm can reduce the production logging interpretation of water content error,accurately calculate the water phase output of oil gas water layer rate value,improve the accuracy of production logging for water.Oil-gas two stalemate water rate correction charts and gas-liquid two stalemate water rate correction chart have been studied out by the experiment chart.And then,the water holding rate correction formula has been calculated with the subsection fitting method.The precise calculation water holding rate value has been achieved through the realization of software.The testing results show that the moistue error differs from production test error with the maximum error of 6.42％ through calculating with the correction water holding rate values.
