Material Description
Modified polymer powder with molecules possessing strong adsorption active groups. Adsorb on the surface of cement particles to form a protective film, inhibit the free water filtration of cement slurry, reduce the invasion of filtrate into the formation, and ensure the stable performance of the cement slurry system under different well temperature conditions.
Core selling point
1. Efficiently control the filtration loss of cement slurry and reduce the invasion of filtrate into oil and gas formations
2. Has little impact on the thickening time and compressive strength development of cement slurry
3. Good temperature resistance, suitable for cementing conditions in multiple temperature ranges
4. Improve the comprehensive stability of cement slurry and reduce the precipitation of free water
5. Excellent compatibility, can be used in combination with various cementing additives
6. Both dry mixing and slurry water feeding are available, and the construction operation is flexible
Product Advantages
-Effectively reducing cement slurry filtration, preventing filtrate from damaging oil and gas reservoirs, and avoiding formation fluid pollution of cement slurry
-Not significantly interfering with thickening time, not hindering the normal development of compressive strength of cement stone in the later stage
-Reduce free water precipitation in cement slurry and improve the stability of cement slurry system
-Good compatibility with cementing aids such as retarders, dispersants, and expanders, suitable for different density cement slurry formulations
-The feeding method is flexible, and it can be dry mixed with cement or added to the mixing water for use
Usage
1. It can be dry mixed with oil well cement or mixed with slurry water, and can be used in combination with other cementing additives.
2. Add and use it in the cementing formula for oil and gas reservoirs and easily permeable formations.
3. Conduct indoor formula trials before on-site use, determine the optimal dosage based on well temperature conditions, and then carry out on-site construction.
4. Mix and stir according to the cementing process, and carry out injection replacement cementing operations.
Storage precautions
Sealed and moisture-proof, avoiding exposure to sunlight and rain; Use up as soon as possible after opening; Wear dust-proof protective equipment during operation.
