Pond, horizontal inlet are connected to mountain flour tank by powder entering valve, mountain flour pipeline；The other end of mountain flour mixing pump is connected by mixing line
It is connected to mud pit；Mountain flour tank is connect by admission line and source of the gas valve with air compressor machine.
A kind of mud exacerbation technique, comprising the following steps:
(1) base slurry circulation: by sand pump, mountain flour mixing pump, mud line, base slurry in mud pit is made to carry out self-loopa.
(2) mud aggravate: mountain flour in mountain flour tank is gasified by air compressor machine, makes it into mountain flour mixing pump, with base starch into
After row mixing aggravates, slurry flows into mud pit again.
The beneficial effects of the present invention are: aggravate to have completely cut off mountain flour heavy weight additive and extraneous contact in operation process in mud,
Realize mountain flour and mud before entering mud pit it is closed it is uniform mix, solve pollution environment, endanger personnel health, waste stone
The problems such as powder material, meanwhile, weighted mud efficiency is improved, labor intensity is reduced.
