Anionic polyacrylamide for oil drilling fluid is a water-soluble polymer designed to modify the rheological properties of drilling muds, improving fluid loss control and borehole stability. This grade is engineered for high-salt and calcium tolerance, making it suitable for offshore and deepwell environments where ionic contamination is common. The product is supplied as a free-flowing white or off-white powder with a molecular weight range tailored for oilfield applications.
The polymer’s anionic charge density enhances its adsorption onto clay particles, reducing viscosity at low shear rates while maintaining gel strength under static conditions. Typical industry specifications for oilfield-grade anionic polyacrylamide include a hydrolysis degree of 20-30% and a molecular weight of 5-15 million g/mol, values aligned with API 13B-1 standards for drilling fluid additives. Its thermal stability allows continuous use at temperatures up to 120°C, a critical threshold for most geological formations.
Primarily used in water-based drilling fluids, this additive is adopted by E&P companies and drilling contractors to minimize fluid loss, prevent differential sticking, and improve hole cleaning. Bulk supply is standard, with packaging options typically including 25 kg multiwall paper bags with PE liners. Buyers should confirm compatibility with their base fluid system, as ionic interactions can vary by formation type and brine composition.

Shandong shuiheng Chemical Co., Ltd. is based in Dongying, Shandong Province, a region known for its concentration of petroleum and chemical industries. The company’s address at No.15 Guangxing Road, Guangrao Town, places it within a key industrial hub for oilfield service providers and chemical manufacturers. Its imported-tier classification indicates a focus on supplying materials that meet international standards for industrial use.
The supplier’s harbor trust tier reflects a baseline verification level, though its response rate is currently unrecorded. This suggests buyers should proactively reach out for technical datasheets, compatibility test results, and bulk supply capabilities. The company’s profile does not list specific certifications, production capacities, or client references, so due diligence is required to confirm adherence to API or other relevant oilfield standards.

Before ordering, verify the product’s molecular weight, hydrolysis degree, and thermal stability through a certificate of analysis or third-party test report. Confirm that the supplier can provide consistent batches, as variations in these parameters can significantly impact drilling fluid performance. Request samples for lab testing in your specific fluid system to assess compatibility and effectiveness under simulated downhole conditions.
Logistics should be coordinated to minimize exposure to moisture and temperature extremes during transit. Confirm the supplier’s lead time for bulk orders, as production schedules may vary. For international shipments, clarify Incoterms (e.g., FOB Qingdao or CIF) and packaging specifications to ensure compliance with import regulations. Payment terms, such as TT or LC, should be agreed upon in advance to avoid delays.
Quality checks should include visual inspection for colour and particle size uniformity, as well as lab tests for molecular weight, hydrolysis degree, and ionic tolerance. Request a material safety data sheet (MSDS) to ensure compliance with handling and environmental regulations. For critical applications, consider third-party inspection of the first shipment to validate the supplier’s claims and establish a baseline for future orders.
