Super Flocculated Drilling Fluid Polyacrylamide Used in Drilling

  SHANDONG FAR EAST GREEN TECHNOLOGY CO.,LTD   was founded in 2011, headquartered in Rizhao city, Shandong  Province, the beautiful new Eurasian continent bridgehead.   SHANDONG FAR EAST GREEN TECHNOLOGY CO.,LTD is a high-tech enterprise engaged in water pollution treatment, sewage treatment, soil ecological restoration, environmental protection equipment, environmental protection design and construction and other businesses. The company has passed the ISO-9001, ISO45001 and ISO-14001 system certification, has a number of product invention patents and utility model patents, more than 30% of the annual revenue invested in product research and development and innovation.  Polyacrylamide is mainly used as drilling fluid in drilling, which can play the following roles:First, polyacrylamide has strong flocculation, which can flocculate mud and cuttings in the drilling process to form a larger flocculation group, which is convenient to clean the bottom of the well. Secondly , polyacrylamide not only has a strong flocculation, but also has a good viscosity and rheology, in the drilling process can lubricate the drill bit and drill pipe, reduce friction, reduce resistance, improve drilling speed, reduce drilling costs.Thirdly , polyacrylamide can protect the sol particles in the drilling fluid, prevent the filtrate from entering the formation to cause clay water swelling, and prevent the wall collapse through multi-point adsorption, adhesive protection and adhesive plugging. Four, in the process of drilling, due to the geological structure, the drilling fluid will be lost, with polyacrylamide can be used to crack, loose rock plugging.  AppearenceSolid Content %Molecular weight ( M)Degree of Ion %Dissolving Time ( Min)Shelf lifeWhite powder > 90%3-25Low-Medium-High
