🛡️ Product Description

Nano-polyester for Drilling Fluid NP-1 is a multi-polymer consisting of alkane sulfonate, alkyl ester, and crosslinking agent. It utilizes special technology to form nano-solid sealing material. The unique functional groups on the molecular chain exhibit strong adsorption ability and adhesion properties.

NP-1 effectively reduces pore-pressure transmission by sealing pore throats and micro-fractures due to its reasonable size distribution in muds. It is suitable for various water-based drilling fluids as well as some oil-based drilling fluids, with a recommended dosage of 3.5-10.5 ppb.

❓ Frequently Asked Questions

1. What are the primary functions of NP-1 in drilling fluids?

NP-1 serves as a nano-solid sealing material that reduces pore-pressure transmission by effectively sealing pore throats and micro-fractures. It helps maintain borehole stability and the integrity of cuttings.

2. What is the maximum temperature resistance for this product?

NP-1 is designed to resist high temperatures up to 240ºC, making it suitable for deep and high-temperature drilling environments.

3. Can NP-1 be used in oil-based muds (OBM)?

Yes, it is suitable for various water-based drilling fluids and some oil-based drilling fluids. However, a compatibility test is required before adding it to OBM systems.

4. What is the recommended dosage for optimal performance?

The recommended dosage typically ranges from 3.5 to 10.5 ppb (pounds per barrel), depending on the specific drilling conditions and fluid requirements.

5. Does NP-1 interfere with geological exploration?

No, NP-1 has low fluorescence properties, which means it can be safely applied to exploration wells without interfering with the analysis of geological samples.

6. How should NP-1 be stored and handled?

It should be stored in a shady, dry, and well-ventilated area. During handling, avoid contact with eyes, skin, and clothing. If contact occurs, flush immediately with clean water.
