SF Silicon Fluoride for Drilling Fluid Anti Collapse and Filtration Reducing Agent
Product Details
This product is an oil field chemical. It is a fluid loss reducer for drilling fluid. Its function is to greatly reduce the water loss of drilling fluid, improve the quality of mud cake and prevent wellbore collapse. The product is mainly composed of natural minerals and a variety of fine chemical raw materials. It is non-toxic and harmless. It is a safe, green and environment-friendly product. It is widely used in oil drilling.
Product Introduction
1. It can be used at 180 ℃ and has good water loss reduction performance and extensive anti pollution ability.
2. The viscosity effect is low, and the drilling fluid has excellent rheology and high lubricity.
3. It has good wall protection and anti sloughing function, and minimizes the occurrence of abnormal conditions in the drilling process.
4. When used together with sf260-i, II and III high temperature silicon fluoride viscosity reducer, the drilling fluid has better performance, can save a lot of other drilling fluid materials, and has better comprehensive economic benefits.
