Module sets stirring depth h, torque value T, pressure value F as conditional parameter, sets running speed V, the interfacial agent stream of drilling machine
Measuring Q, surfactant concentration W is target component；
Step 4: when boring in whipping process under drilling machine, depth h, torque value T, pressure value being stirred according to monitoring result conditional parameter
F is the value range of conditional parameter, and dynamic select and control system execute its corresponding target component (running speed V, interface work
Property agent flux Q, surfactant concentration W)；
Step 5: after being drilled into setting stirring depth under drilling machine, completing intelligent construction operation.
