Adaptive hydraulic shaker

By designing an adaptive hydraulic oscillator, utilizing the cooperation of the moving and stationary valve discs and the baffle structure, combined with a turbine and drive shaft, adaptive parameter adjustment for complex downhole conditions is achieved. This solves the problem that existing hydraulic oscillators cannot adapt to complex conditions, and improves drilling efficiency and wellbore control accuracy.

Abstract

本发明涉及石油天然气钻井井下工具技术领域，公开了一种自适应水力振荡器用于连接钻铤和钻具，包括套筒组件、静阀盘、动阀盘、涡轮、传动轴和挡板。静阀盘设置于通道内，且与通道的内壁固定连接，静阀盘上设置有第一通孔。动阀盘上设置有第二通孔，动阀盘的侧壁与静阀盘朝向第一端的侧面滑动配合。传动轴分别与涡轮和动阀盘固定连接。挡板绕通道的轴线可转动地设置于通道内，挡板的侧壁与静阀盘朝向第二端的侧面滑动配合，挡板上设置有第三通孔，且第一通孔、第二通孔和第三通孔沿通道的轴向位置对应。本发明可解决现有水力振荡器无法自适应调节过流面积、流体脉冲强度、振荡参数，不能适配复杂多变的井下工况的问题。
