產(chǎn)品介紹

　　磺甲基酚醛樹脂為棕色自由流動(dòng)粉末，是一種有效的高溫抗污染降濾失劑，加入一定數(shù)量的SMP可在淡水和鹽水鉆井液中得到滿意的API和HTHP濾失量，產(chǎn)品分為兩種類型，SMP-I用于淡水和低濃度鹽水體系，SMP-II用于高濃度鹽水體系，SMP-Ⅲ多用于深井超深井，其抗溫能力為180℃，通常加量為2%～3%。

Sulfomethylated phenolic resin (SMP) SMP is a sulfomethylated phenolic resin. The product is a brown free-flowing powder. SMP is an efficient FL control agent with good high temperature and chemical contamination resistance.By addition of certain amount of SMP,a satisfied value of API or HTHP FL can be surely achieved in fresh water system as well as in salt water system up to saturation.The product is of two types SMP-I for fresh or gentle brackish water systems and SMP-II for high salinity case.Its temperature stability is about 180℃.The routine dosage of SMP may vary in the range of 2%～3%.
