Potassium Polyacrylate Inhibitor
1. Product Description
Chemical Name: Potassium Polyacrylate. It's a polymer from acrylic acid monomers in potassium salt form. Appears as white or light yellow powder/granules. Features good water solubility, inhibition, and stability, effectively curbing clay hydration swelling in drilling fluid and stabilizing wellbores.
2. Performance Indicators
Medium - molecular - weight (10â?¶ - 10â?· Daltons). Soluble in water, forming clear or slightly turbid solutions. Inhibits clay mineral swelling, reducing drilling fluid filtrate loss. With good heat resistance (over 120�°C), suitable for high - temperature deep wells. Aqueous solution is weakly alkaline (pH 8 - 10), and it's non - toxic, meeting environmental standards.
3. Scope of Application
Ideal for water - based drilling fluid systems, especially those needing to control clay swelling. Suited for mud shale and high - clay - content strata, preventing wellbore collapse and diameter reduction. Applies to medium - to - high - temperature wells (â?¥120�°C), used in land and offshore drilling, deep/ultra - deep well operations, and drilling in complex formations like mud shale and salt - gypsum layers.
4. Usage and Dosage
Can be added directly to drilling fluid and stirred, or pre - dissolved in a small amount of water to form a concentrate before adding. Recommended dosage is 0.1% - 0.5% (by weight) of total drilling fluid volume. In high - clay or unstable - wellbore scenarios, it can be increased to 0.5% - 1%, adjusted according to downhole conditions.
5. Application Scenarios
In mud shale formations, it averts wellbore collapse from clay swelling. In high - temperature deep wells, it maintains drilling fluid stability. In complex formations, it prevents wellbore diameter reduction and drill sticking. Its eco - friendly nature makes it suitable for offshore drilling and environmentally sensitive areas.
6. Advantages
Highly efficient in inhibiting clay swelling, ensuring wellbore stability. Environmentally safe, non - toxic, and pollution - free. Adaptable to various drilling conditions. Cost - effective with a small dosage bringing notable effects.
7. Precautions
Ensure full dissolution to avoid agglomeration. Test compatibility with other additives. Store in a dry, ventilated place, away from moisture and heat. Wear gloves and masks during use to avoid skin and eye contact.
Conclusion
Potassium polyacrylate inhibitor is an efficient and eco - friendly drilling fluid additive, crucial for various complex formations and high - temperature deep wells due to its outstanding inhibitory and stable properties. Contact for more info or customized services.
