High temperature resistant starch for drilling fluids

Main ingredients

High temperature resistant starch for drilling fluid refers to the use of chemical, physical, or biological methods to introduce different substituents into molecules, gelatinize or degrade them, and produce starch derivatives with certain special properties.

Main ingredients

The product is a white or light yellow powder, which has both the salt resistance of starch products and the temperature resistance of polymer products. It is used as a drilling fluid treatment agent and has a significant filtration loss reducing effect in freshwater mud and saline mud.

Specification

Product features

1. Strong temperature resistance, with a usage temperature of up to 180 ℃, stable performance, and low content characteristics
2. Has excellent water loss reduction performance, uniform solubility, and good thickening, shear resistance, and pollution resistance
3. It is easy to prepare, maintain, and handle on site. If solid-free drilling fluid is prepared, it will not cause solid-phase damage to the reservoir.

Usage

Recommended dosage: (volume ratio)

The recommended dosage for freshwater drilling fluid is 1.5% to 3.0%, and for saline drilling fluid is 3.0% to 5.0%.
