水井调剖半径与地层吸水参数关系式的确定

Determination of Relation Formula for Radius of Profile Control and Injection Parameters of Reservoir

针对文明寨、卫城、马寨油田注水井调剖的实际情况，统计分析了大部分调剖井的调剖半径、地层吸水参数等资料，根据注水井调剖的基本原理，导出了调剖措施半径与地层吸水参数之间的关系式，并由此求得了确定措施半径的经验公式。经应用验证，与实际情况吻合程度较高，对今后注水井调剖具有一定指导作用。

According to the condition of profile control in Wenmingzhai,Weicheng and Mazhai Oil Fields, this paper counts and analyzes a lot of information,which includes measure radius and injection pa rameter of oil reservoir etc. On the basic principle of profile control, the author gets the relation formulas between radius of profile control and injection parameters of oil reservoir. The experience formulas to de termine measure radius are also given at the same time. Verified by application,the formulas are in accor dance with practical condition.
