Rigid plugging agents for drilling fluids

Main ingredients

The rigid plugging agent for drilling fluid is made from calcite, polypropylene fiber, and elastic particles as raw materials.

Nature and Use

This product is made of white or light white particles, which can quickly and effectively seal complex geological conditions encountered during drilling, reduce drilling fluid loss, prevent solid and liquid phases from entering the reservoir, and stabilize the wellbore.

Specification

Product features

1. Good compressive and temperature resistance,
2. Reduce leakage and plugging frequency,
3. Reduce production costs, improve cost-effectiveness,
4. Effectively solved the problems of poor pressure bearing capacity and plugging effect of plugging agents, easy leakage, high production cost, and low cost-effectiveness.

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%.
