Sulfonated Lignite (SMC) | Drilling Fluid Fluid Loss Reducer<\/div>\n
1. Product Introduction<\/strong><\/div>\n
\n
\n<\/div>\n
Sulfonated Lignite (SMC) is a high-efficiency water-based drilling fluid additive. It is produced by cross-linking lignite humic acid with sulfonic acid groups (-SO3Na) and chromium salt. The product has three core functions: viscosity reduction, fluid loss control and wellbore collapse inhibition, with excellent cost performance. It can be well compatible with various drilling fluid additives such as CMC, SPNH, Xanthan Gum and K-PAM without adverse chemical reactions, serving as a versatile and reliable multifunctional treatment agent for water-based drilling systems.<\/div>\n
2. Product Applications<\/strong><\/div>\n
\n
\n<\/div>\n
2.1 Core Drilling Fluid Functions<\/strong><\/div>\n
SMC is mainly used as a fluid loss reducer and viscosity stabilizer for water-based drilling fluids. It effectively controls mud filtration loss, improves the compactness and smoothness of filter cake, and inhibits hydration, dispersion and expansion of clay minerals. Under high-temperature and high-salt downhole conditions, it prevents mud thickening, performance degradation and solid phase settlement, and maintains stable rheological properties of drilling fluids throughout the drilling process to ensure continuous and efficient operations.<\/div>\n
2.2 Application Scenarios<\/strong><\/div>\n
It is widely applicable to conventional wells, medium-deep wells, directional wells and high-salt complex oil and gas reservoirs. Compatible with fresh water, salt water and saturated brine drilling fluid systems. It can be compounded with various conventional oilfield additives to build high-stability and high-temperature resistant mud systems suitable for complex downhole working conditions.<\/div>\n

4. Product Advantages<\/strong><\/div>\n
\n
\n<\/div>\n
Reliable High-temperature Resistance<\/strong>: It maintains stable performance at 150\u2103-180\u2103 without performance attenuation, perfectly adapting to high-temperature drilling environments of medium and deep wells.<\/div>\n
Excellent Fluid Loss Control<\/strong>: It significantly reduces drilling fluid filtration loss and forms dense, impermeable and high-quality filter cake to stabilize wellbore and ensure downhole integrity.<\/div>\n
Superior Salt and Calcium Resistance<\/strong>: It remains stable in high-salinity and calcium-containing formation water without deterioration, ideal for complex salt-bearing oil and gas reservoirs.<\/div>\n
Excellent Compatibility<\/strong>: Fully compatible with all conventional water-based drilling fluid additives without any negative impact on mud system performance.<\/div>\n
High Cost Performance<\/strong>: With stable quality and low comprehensive application cost, it is the preferred additive for large-scale conventional and medium-deep well drilling operations.<\/div>\n
5. Packaging and Storage<\/strong><\/div>\n
\n
\n<\/div>\n
Packed in 25kg paper-plastic composite woven bags with excellent sealing and moisture-proof performance. Store in a dry, cool and well-ventilated warehouse. Avoid moisture, rain and long-term exposure to humid environments to prevent agglomeration. Under standard storage conditions, the product can maintain stable performance for a long time.<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
