利用早期勘探的几口探井的中途及完井地层测试数据作节点分析,可为探井提供合理的产能预测和配产方案。本文利用节点分析法原理,针对探井早期预测的测试数据,提出了合理绘制流入、流出曲线的基本方程与适合新探区的摩阻系数,并针对实际井提供了配产方案。经国内西部某油田近五年的开采证实,具有很好的现场指导作用。

In application of the formation test data of well drilling and well completion collected from some early exploration wells, node analysis was made so as to draw a reasonable plan for the production forecast and production regulation. On the basis of the node analysis principle and early well test data, the present article suggests the basic equations to draw input and output curves and provides friction-damping coefficient for new prospect areas. The above mentioned method has been proved to be very useful in certain oil fields' production of west China for the past five years.
