临界流速的确定及其在油田开发中的应用

Determination of Critical Rate and Its Application in Oio-Field Development

临界流速在油田开发中具有重要的意义，本文从储层速度敏感性评价实验出发，给出确定临界流速方法，并推导出室内临界流速转换为油藏条件下临界流速公式，同时将临界流速与油田开发结合起来确定合理开采速度、速敏损害半径及开发试验中驱替速度大小。

Critical rate is of great inportance in oil field development. On the bsis of the evaluation test of reservoir rate sensitivity, this paper presents the method of determing critical rate, and derives the formula of transforming lab critical rate into the critical rate under reservoir condition. At the same time, critical rete is combined with the oil field development to determine reasonable production rate, sate sensitivity damage radius and displacing velocity in development tests.
