Shandong Ecolink Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of drilling fluid additives in China, featured by quality products and good service. If you're going to wholesale high quality drilling fluid additives, welcome to get more information from our factory.
Product Overview
Cationic Polyacrylamide (CPAM), also known as cationic PAM or shale inhibitor, is an important chemical treatment agent used in oilfield drilling operations. It is specifically designed to address issues such as shale and clay swelling upon water contact and wellbore instability or collapse. As a drilling fluid additive, CPAM acts as a "wellbore stabilizer" - requiring low dosage, delivering strong performance, and providing long-lasting effects. It is a core treatment agent when drilling through shale, clay, and other collapse-prone formations. As a highly efficient clay stabilizer, it fundamentally reduces downhole risks caused by water-sensitive formations.
Products Description
To address common customer concerns such as unstable performance and batch-to-batch inconsistency in water treatment chemicals, we implement standardized production processes and strict quality control systems to ensure that our Cationic Polyacrylamide (CPAM) maintains stable and reliable quality.
This oilfield-grade CPAM undergoes multiple layers of testing from raw material selection to final delivery and complies with international standards. It provides customers with greater confidence during long-term use and reduces risks associated with switching suppliers. Whether used as a drilling fluid anti-collapse agent or a water-based drilling fluid additive, our product consistently delivers stable and dependable performance.

Production & Quality Assurance
ECOLINK's Cationic Polyacrylamide (CPAM) is produced using a mature manufacturing process, supported by a full-process quality control system to ensure product stability. All key parameters are strictly controlled during production rather than relying solely on final inspection. Each batch is traceable and accompanied by testing data for customer verification.
Through process control combined with data support, procurement uncertainty is significantly reduced. This allows customers to proactively avoid quality risks and ensure more reliable purchasing decisions. As a professional manufacturer of oilfield drilling fluid additives, we guarantee stable and consistent performance for every batch.
Recommended Dosage
General recommendation: 3–7 ppb (lb/bbl) or 0.1%–0.6% (by volume)
For highly water-sensitive formations: dosage can be increased up to 0.4%
Application Method
- It is recommended to prepare a 0.5%–1% solution first. Slowly add the powder into water under continuous stirring.
- Ensure sufficient mixing to achieve full dissolution.
- Avoid adding dry powder directly into the mud tank to prevent clumping.
- Maintain proper mixing conditions during application.
- When used in combination with potassium chloride (KCl), the potassium ion concentration should not be lower than 60,000 ppm.
