Drilling plugging agent
Drilling plugging agent is a natural plant polymer composite material with good water swelling bridging and plugging kinetic energy, strong adhesion, and is not limited by particle size matching compared to traditional drilling plugging agents. It is suitable for various mud systems, can be used to seal lost circulation layers, and can also protect low-pressure production layers (oil, gas, water, etc.).

Features:
1 pair of pores and micro cracks, with fast plugging speed and good effect.
2. It can quickly form a non permeable shielding belt with a certain strength to prevent the invasion of liquid and solid phases in the working fluid into the reservoir, so as to prevent damage to the reservoir. The shielding belt can be released through reverse perforation.
3 can significantly reduce the filtration loss of mud without affecting its rheological properties, and has excellent temperature resistance.
4. Not affected by electrolyte contamination, non-toxic, and harmless.
Usage:
1. Use 1-2% to prevent leakage.
Seal the pores and microcracks of the sand layer and protect the reservoir with a dosage of 2-4%.
3. Seal the severely leaking layer with a dosage of 4-6%.
Packaging:
The product is packaged in a "three in one" bag consisting of an outer textile bag and an inner plastic bag, with a mass of 25kg per bag and an allowable error of+1%
The product should be placed in a cool and dry place to prevent exposure to sunlight, packaging damage, and moisture.
