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.
