Modified starch is a high-performance water-based drilling fluid additive produced from natural starch through chemical modification. It is primarily used to control fluid loss, protect the wellbore, improve filter cake quality, and stabilize drilling fluid properties. Compared to ordinary starch, modified starch offers superior temperature, salt, and contamination resistance, maintaining stable performance in drilling environments ranging from 120\u00b0C to 140\u00b0C.<\/p>\n
The product effectively minimizes filtrate invasion into the formation and forms a thin, impermeable filter cake, thereby reducing wellbore instability and formation damage. It also improves the rheological properties of the drilling fluid, enhancing overall drilling efficiency. Modified starch is highly compatible with various other additives\u2014such as PAC, PHPA, CMC, and SMP\u2014and is widely used in water-based drilling fluid systems for oil, natural gas, shale gas, geothermal, and horizontal wells.<\/p>\n
