摘要
在油田开发中,童氏标准曲线经常用来拟合实际生产数据。对一些复杂油藏来说,在采出程度较低时用童氏标准曲线预测的含水率往往比实际值高,有必要对童氏标准曲线进行校正。本文通过对童氏图版公式中统计常数7.5的适应性分析,提出了一种新的统计常数的确定方法,使其更加符合单一油藏的含水率与采出程度变化规律。实践表明:用改进后的童氏曲线图版预测油田的含水率是有效的,对评价开发具有重要指导意义。
In the oilfield development,Tong＇s standard curve is often used to fit the actual production data.In the Complex reservoir,the forecast moisture content of the Tong＇s standard curve is often higher than actual value,therefore Tong＇s standard curve need to be improved.By Tong＇s statistical analysis of adaptive constant 7.5 presents,a new statistical constant determining ways to make it more in line with a single reservoir of water content and degree of reserve recovery was studied.Practice has proved that： Using the improved Tong＇s curve,the predicted moisture content of oil fields is effective for evaluating development of important guiding significance.
