The shaft friction value is still in the linear growth phase. The self-balanced method may resolve the problem that the shaft friction is not ful used in Guizhou Province.

侧摩阻力值还处于线性增长阶段，且数值十分可观，据此有望解决贵州省目前桩基承载力侧摩阻力不能充分利用的问题。

When the drilling is finished, water, combined with chemicals designed to reduce friction and serve other purposes, is injected from the surface into the well shaft at very high pressures, thereby fracturing the shale rock formations far below, and making it possible to extract economically the natural gas embedded in the shale.
