This set of components can rotate to the back leakage discharge hole and pump the bottom of the alignment.
这样可以使整套部件旋转至背板漏液排出孔与泵的最底端对齐。
In the course of transmission, mud pulse signal mainly disturbed by drilling pump, engine in the bottom hole, air bladder contained in mud and movement of drilling equipment.
泥浆脉冲信号在传输过程中主要受钻探泵、井底动力机、泥浆中的气泡及活动钻具的干扰；
This can render the entire set of components to rotate back leakage from the hole and pump alignment at the bottom.
这样可以使整套部件旋转至背板漏液排出孔与泵的最底端对齐。
To pump the drilling fluid until a sample from the bottom of the hole reaches the surface.
泵送流体直到岩样从井底到达地表为止。
