Middle section operation, to guarantee the normal operation of the stabilization and screw feeder of flow；
(3), the preparation of fracturing fluid:
Suitable driving screw feeder 18 or auxiliary screw feeder 21 are selected, powder drag reducer is packed into corresponding trunk powder
Defoaming agent is packed into liquid additive tank 11 or liquid inlet tube 12 is inserted into defoaming agent material by feed bin 19 or auxiliary dry powder feed bin 20
Bucket opens water inlet gate valve 3, starts centrifugal water pump 4, and the flow of the aperture regulation centrifugal water pump 4 of adjustment water outlet gate valve 3 starts liquid
Body additives pump 13, opens ball valve Vb15, starts driving screw feeder 18 or auxiliary screw feeder 21, opens ball valve Va7 or ball
Valve Vc25 completes the addition of fracturing fluid powder drag reducer and defoaming agent, while powder drag reducer is filled online with liquid, starting
Fracturing blender truck, while other additives and proppant is added；
(4), start fracturing unit truck, start fracturing work；
(5), when stopping construction, successively stop driving screw feeder 18 and auxiliary screw feeder 21, close ball valve Va7 and ball
Valve Vc25 closes ball valve Vb15, stop liquid additive pump 13, then stops centrifugal water pump 4, closes water inlet gate valve 3.
