I. Brief Product Description:

Adopting the concept of molecular structure design, through the selection of temperature-resistant and salt-resistant monomers, and polymerized by solution method, DYDSP is a brand new polymer filter loss depressant, which can be used in the construction of drilling fluids in deep wells, ultra-deep wells, and high mineralization salt water.

II. Product features:

 DYDSP-1 Temperature resistant 220℃.DYDSP-2 Temperature resistant 180℃.

 Resistant to salt up to saturation, DYDSP-1 Calcium resistance up to 5000mg/L.

 Both can effectively reduce the HTHP filtration loss of drilling fluid and improve the quality of mud cake.

 Recommended dosage 1%~ 2%.

III. Packaging and Storage:

 25 kgs Composite packaging bag or as per clients requirements

 Store in dry area. Avoid open fire, strong oxidant, high-temperature

 Period of validity: 12 months
