Product Description

WH-7 is formulated with a variety of high-efficiency surfactants, wetting reversing agents, organic solvents and other auxiliaries. It has a strong penetrating effect and can quickly penetrate into the mud cake formed in the well wall during the drilling process. The mud cake is dispersed and eroded away, thereby improving the cementing ability of the cement slurry and the contact surface.

Characteristics

Non-toxic, odorless, non-corrosive.

WH-7 has strong oil-washing properties, which can effectively remove and displace oil-phase materials in the well, and change the oil-wet interface in the well to the hydrophilic interface, thereby improving the cementing ability of cement slurry.

Has good compatibility with oil-based mud.
