Phenolic Resin SMP-2

Phenolic Resin SMP - 2 1. Product Description Chemical Name Phenolic Resin. Type SMP - 2, a sulfomethylated phenolic resin, is water - soluble. Appearance It shows as brown or dark - brown powder/granules. Characteristics Exhibits great high - temperature, salt, and pollution resistance. Effectively cuts drilling fluid's fluid loss and stabilizes wellbores. Action Mechanism Adsorbs on wellbore and clay particle surfaces, forming a compact filter cake to minimize filtrate entry into the formation. 2. Performance Indicators Temperature Resistance Outstanding high - temp resistance, suitable for over 200 C environments. Salt Resistance Maintains stable performance even in saturated brine. Fluid Loss Markedly reduces API fluid loss, usually < 10 mL/30 min. pH Value Aqueous solution is weakly alkaline (pH 8 - 10). Solubility Easily dissolves in water, forming clear or slightly turbid solutions. Environmental Friendliness Low - toxicity, low - pollution, meeting environmental standards. 3. Scope of Application Drilling Fluid System For water - based drilling fluids, especially in high - temp and high - salinity scenarios. Geological Conditions Appropriate for complex strata like high - temp/high - pressure, salt - gypsum, and mud shale formations. Temperature Range Suits high - temp conditions (over 200 C). Application Scenarios High - temp deep and ultra - deep wells. Salt - gypsum and mud shale formations. Drilling in complex formations. 4. Usage and Dosage Usage Direct Addition Slowly add SMP - 2 powder to drilling fluid and stir well for even distribution. Premix Dissolution Dissolve it in a small amount of water first, then add the concentrate to the drilling fluid. Dosage Regular Dosage Recommended 1% - 3% (by weight) of total drilling fluid volume. High - temp/High - salinity Environment Can increase to 3% - 5% in such conditions. Dynamic Adjustment Adjust dosage according to downhole factors like rock type, temp, and pressure. 5. Application Scenarios High - temperature Deep Wells Reduces fluid loss and stabilizes wellbores in high - temp deep and ultra - deep wells. Salt - gypsum Layers Prevents wellbore collapse and excessive fluid loss in salt - gypsum layers. Complex Formations Works for mud shale and sandstone formations to avoid wellbore collapse and high fluid loss. 6. Advantages High - efficiency Fluid Loss Reduction Significantly cuts fluid loss and stabilizes wellbores. High - Temperature/High - Pressure Resistance Performs stably in high - temp and high - pressure settings. Salt Resistance Stable in saturated brine. Environmental Safety Low - toxicity, low - pollution, environmentally friendly. Cost - effective Small dosage, great results, high cost - performance.
