同时由于从井口到井底始终存在着连续的液相流，常规井下动力钻具和随钻仪器的性能不受影响，可以进行正常的井眼轨迹控制。
Meanwhile, the downhole motor and MWD are not affected and wellbore trajectory can be controlled because of the continuous fluid phase flow throughout the bore hole.
井下随钻流量监测技术具有很高的监测精度，能够对井眼压力进行更加精细的控制，还能够对压力梯度范围很好的确定。
The technology of monitoring well bottom while drilling has high precision, which can control borehole pressure more precise, but also the scope of the pressure gradient is well established.
