الملخص EN

It is a hot topic for deep/ultradeep wells to improve rock-breaking efficiency and drilling speed by available downhole energy.

Based on different downhole energies and working conditions, specialized plunger pump is proposed to convert longitudinal vibration of drilling string into rock-breaking energy.

Technical design is developed to generate high-pressure water jet.

And then a simulation model is built to verify feasibility of the technical design.

Through simulation, the influence law of key factors is obtained.

On this basis, this device is tested in several wells.

The result indicates this device can increase drilling speed as much as 136%.

Meanwhile the harmful vibration can be absorbed.

The energy from drilling string vibration is of high frequency and increases as well depth and formation anisotropy increase.

By reducing adverse vibration, this device is able to increase the drilling speed and the service life also meets the demand of field application.

The longest working time lasts for more than 130 hours.

The performance of this device demonstrates great application prospect in deep/ultradeep resources exploration.

To provide more equipment support for deep/ultradeep wells, more effort should be put into fundamental study on downhole drill string vibration and related equipment.
