Composite plugging agent for drilling fluid

Main ingredients

This product is mainly composed of plant hard fruit shells, mica, and other plant fibers.

Nature and Use

Yellow or grayish yellow powder, non-toxic, non corrosive inert material that expands when exposed to water.

Specification

Product features

1. Fast plugging speed and good effect on pore and micro crack leakage.
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. It 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

Recommended dosage: (volume ratio)

1. 1-2% for preventing leakage.
2. Seal the pores and microcracks of the sand layer, protect the reservoir, with a dosage of 2-4%.
3. Seal the severely leaking layer with a dosage of 4-6%.
