API modified starch API drilling starch oil grade corn starch,China ZKTQ price supplier

Common Name: Modified Starch

Product Code: FLO

Product Description:

 Modified starch for drilling is modified from natural maize starch. Under certain temperature and moisture, the chemical bond between molecules is broken and molecule structure changed. Starch derivative is achieved through further drying and grinding. The product swells and dissolves in cold water and forms Paste liquid of certain concentration, which absorbs water, condenses and deposits less, and easily applied. Oilfield starch is non-toxic, pollution-free, degradable and environment-friendly.

Standard:

This oil grade Corn Starch reaches GB/T5005-2010 standard.

Scope of Application:

The product belongs to water-based drilling fluid additive range, applicable to non-reservoir interval as fluid loss control agents.

Key Feature:

Derived from natural starch, the product is mainly used as fluid loss additive in salt water or saturated salt water. It is comparative with CMC in reducing fluid loss but better than CMC in salt tolerance. The product affects little to rheology of mud, non-tackifying and compatible with other additives.

Usage:

The product can be added into drilling fluid directly or used to prepare compound solution with other additives for mud treatment or performance maintenance. The common dosage is 1% ~ 3%.

Application Temperature:

The product is designed for normal temperature. Its temperature resistance reaches 100 °C .

Packaging and Storing:

Triple bag with PE lining, 25 Kg/bag

The product requires ventilation and drying, away from moisture, fire and high temperature.
