Cationic Clay Stabilizer

Chemical ingredients: Cationic Quaternary Ammonium Salt Polymer.

Properties:

Cationic clay stabilizers (including novel cationic polymers such as quaternary ammonium salts and polyamines) are strongly cationic aggregation electrolytes. They appear as transparent to pale yellow viscous liquids with a specific gravity of 1.02 g/cm³. Their decomposition temperature is 150°C. Most products are chlorine-free, low-toxicity, and biodegradable, meeting environmental protection requirements.

Cationic clay stabilizers exhibit outstanding core performance, adapting to diverse operating conditions and systems. Certain types demonstrate temperature resistance exceeding 200°C. Their strong resistance to water washing makes them suitable for demanding scenarios like high-temperature steam injection and thermal recovery. They also offer excellent compatibility, working well with fracturing fluids, acid solutions, polymer systems, and other acid agents or fracturing agents.

The mechanism of action for cationic clay stabilizers is well-defined, offering significant application value. By neutralizing negative charges on clay surfaces, they effectively prevent the hydration, dispersion, and migration of bentonite minerals. This extends water injection cycles and ultimately achieves the application goal of enhancing oil production.

Specification:

Using:

1. Fracturing Fluid System

Application Scenario: Suitable for reservoir stimulation processes such as hydraulic fracturing. Can be used as a pre-treatment fluid for formation conditioning or directly blended as an additive into water-based fracturing fluid systems.

Core Function: Suppresses swelling issues caused by contact between water-based fluids and formation clays during fracturing. Simultaneously reduces fluid loss and minimizes damage to formation matrix. Maintains fracture conductivity to ensure fracturing effectiveness.

Recommended Dosage: 0.3%~0.8% (based on total fracturing fluid mass). Adjust to upper limit for high-clay formations.

2. Water Injection Development

Application Scenarios: Suitable for conventional water injection, zoned water injection, and other development modes. Particularly well-suited for low-permeability, ultra-low-permeability, and highly water-sensitive reservoirs. Enables long-term stable injection operation.

Core Function: Mitigates pressure buildup caused by clay swelling and particle blockage during water injection. Enhances reservoir water absorption index. Improves water injection coverage. Ensures water injection development efficiency.

Recommended Addition Ratio: Conventional reservoirs is 0.1%~0.5% (based on total injected water mass). Low-permeability and highly water-sensitive reservoirs may be adjusted upward to 0.5%~0.8% as appropriate.

3. Acidizing, Workover, and Completion Operations

Application Scenarios: Covers matrix acidizing, fracturing acidizing, workover fluid circulation, completion fluid immersion, and other operational phases. Compatible with acid fluids and various water-based working fluid systems.

Core Function: Prevents reaction between acid fluids/water-based working fluids and formation clays. Avoids secondary reservoir damage caused by clay swelling and dispersion migration. Effectively preserves original reservoir permeability.

Recommended Dosage: Acid Fluid Systems: 0.5%~1.0% (based on total acid fluid mass). Water-Based Workover/Completion Fluids: 0.3%~0.6% (based on total working fluid mass).

Packing and storage:

Cationic clay stabilizer should be packed 200kg plastic drum or 1000kg/IBC drum. Stored at room temperature, the storage period is one year.
