摘要
在我国各油田应用的人工地震增油技术中,所用的起振器的激振力是随激振频率以恒定方式变化的,最佳激励参数的选择不太方便。本文提出了一种新方法,利用具有常力扫频和定频变力功能的起振器,大大方便了最佳激振参数的选择。
おn technique for increasing output of oil with artificial earthquake in oil fields all over China the exciting force of the exciter changes with frequency indentically so that selecting the optimal parameters for excitation is not convenient. A newmethod is presented which uses a exciter possessing sweep function under constant exciting force or variable exciting force under constant frequency and is easy for choosing the optimal excitation parameters.
