Abstract

The invention provides a vortex vibration device. The vortex vibration device comprises a casing, wherein a movable valve plate driven by a driving device to rotate is arranged in the casing, a round vortex chamber is formed in the vibration device, at least one liquid inlet groove is tangentially connected with the vortex chamber, and a vortex chamber outlet is formed in the center of the vortex chamber and connected with a liquid outlet; at least one bypass channel is connected with the liquid outlet; a movable valve liquid inlet hole is formed in the movable valve plate and is communicated with the liquid inlet groove and the bypass channel alternately. With adoption of the structure, the vortex vibration device has the beneficial effects as follows: liquid flow entering the vortex chamber and the bypass channel is changed by movable valve plate and fixed valve plate assemblies, the vibration effect caused by a vortex effect produced in the vortex chamber is better than that caused by open area changes, the vibration effect of the whole vortex vibration device is more obvious, and matching with a spring nipple or a jar in a drilling process is not needed.

Description

technical field [0001] The invention relates to the fields of petroleum and natural gas exploitation and drilling tools, in particular to an eddy current vibration device. Background technique [0002] With the wide application of highly deviated wells and horizontal wells, during the drilling process, due to the self-weight of the drilling tool, the friction between the drilling tool and the well wall during drilling is large, resulting in the back pressure of the drilling tool, which seriously affects the drilling of horizontal wells Therefore, reducing friction, increasing dynamic drilling pressure and improving drilling efficiency are urgent problems to be solved in current drilling engineering. It has been found through research that by applying appropriate periodic axial vibration to the drill string, the static friction between the drill string and the well wall can be changed into dynamic friction, which can greatly reduce the friction resistance in the drilling proc...
