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

It can be prepared into an aqueous solution for use or directly added to the drilling fluid circulation system. When adding directly, attention should be paid to the feeding speed, and a uniform slow addition or intermittent addition method should be used.

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