ABSTRACT
Resource reserves can be effectively controlled through slim borehole horizontal drilling, which can significantly reduce costs and enhance efficiency. Therefore, it has been widely used in petroleum, geothermal, shale gas and water resources exploration. But the large friction between the drilling string and borehole can cause downhole accidents. In this paper, a new method of vibrating drag reduction is proposed, with using turbine to drive the rotary valve to control flow. Axial vibration excitation produced by high-pressure water can greatly reduce the friction. Firstly, a rotary valve mathematical model with flow hydraulic oscillation and vibration is established, whose work characteristics are simulated using numerical methods. And then lab experiments are conducted to verify the design.
