SF260-Ⅱ Silicon Fluorine High Temperature Viscosity Reducer for Drilling Fluid
Product Details
Product Introduction
In order to meet the needs of deep and ultra deep well drilling of various types of wells under complex geological conditions, Silicon Valley Research Institute has developed a new generation of silicon fluoride viscosity reducer sf260 - Ⅱ with high temperature resistance and composite salt resistance. The product not only maintains the characteristics of sf260, but also significantly improves the ability to inhibit shale hydration, improve the wall building function of drilling fluid, high temperature resistance (Shengke 1 # successfully passes when drilling 7002m and bottom hole temperature 240 ℃) aging performance and rock salt and salt gypsum layer pollution resistance, greatly simplifies the composition of ultra deep well drilling fluid, and has stable performance and downhole safety. It is unique at home and abroad. It shows super viscosity reduction and stability under complex conditions such as ultra-high temperature and high density (more than 2.3g / cm3), and can extend the mud stability period by 3-5 times. It is conducive to improving the drilling efficiency and benefit of deep and ultra deep wells, and realizing the purpose of rapid and safe drilling. The recommended dosage is 1 ~ 2%.
