    Product Detail

    Product Description

    DLA-1 is polymerized by aluminium salt and various complexing agents through complex coordination polymerization. Under low pH condition, DLA-1 forms a large number of precipitate to seal pore throat and micro-fracture, so near borehole will be solidified and borehole stability will be enhanced. DLA-1 can inhibit clay from hydrating and swelling, and has slight impact on the rheology and filtration control property. Its recommend dosage is 3.5 – 7.0ppb.
