Drilling fluid plugging agent - chelating aluminum. CS-FCS
Product Features and Applications
CS-FCS is a drilling fluid plugging agent mainly composed of water-soluble complex. This product has both acidic and alkaline properties. Under alkaline conditions, CS-FCS can quickly dissolve in the mud. During drilling, high pH filtrate penetrates into the formation and contacts with neutral or slightly acidic formation water, causing a decrease in pH value. ZK-FCS reacts quickly in the low pH environment to form precipitation and deposit in the micro-cracks of the formation, while forming a dense protective film, effectively plugging the pores and micro-cracks of the formation, and stabilizing the wellbore. It is suitable for various water-based drilling fluid systems, including fresh water and salt water systems.
Product Advantages
Heat-resistant up to 150℃;
It has both acidic and alkaline properties, existing as a soluble complex under alkaline conditions and reacting quickly and precipitating under neutral or slightly acidic conditions;
Effectively seals micro-cracks in the formation and forms a dense protective film on the wellbore rock surface to prevent filtrate from penetrating into the formation and stabilize the wellbore;
No fluorescence interference, does not affect geological logging and testing;
Environmentally friendly and non-toxic.
