Product Description
Polyol belongs to polyether modified products, which not only can effectively prevent clays from dispersing, reduce swelling pressure, but also can effectively lubricate and protect oil and gas reservoir. In addition, it is low fluorescent, low toxic, and environment-friendly with the good comprehensive advantages. It can form hydrophobic film on the surface of metal and shale, and the wettability reversal will happen. Because it contains many adsorption groups such as COC and hydroxyl, so it can effectively avoid drilling cuts from flocculating or adhering, prevent bit balling, and increase ROP. It can be directly added into various water-base drilling fluids. Its recommended dosage is 1.0 – 3.0% (v/v).
