sf fluorine silicon filtrate reducer for drilling this product is the oil field chemical and mud aids which has the function of minimizing the waster loss and preventing well collapse. this production mainly composes by natural mineralizer and many kinds of fine industrial chemicals, which this kind of product is green and environmental protection with non-toxic, and non-pollution. it is the widespread used aids. a. production description 1. silicon stability agent has strong ability of anti- temperature. the drilling mud still has very good function of failing water and anti-pollution when the temperature is higher than 180℃. 2. excellent mud viscosity reduction rate, rheological adjustment and the high speed of progress. 3. fastening wall against collapse well, reducing the abnormal situation occurrence as far as possible. 4. saving other material, synthetically economic efficiency is better when used with sf260 fluorine silicon high-temperature drilling liquid thinner together. b. performance index table1 physic-chemical performance item index appearance black mobile solid powder ph value ≤ 12 triage amount % ≤ 5 drying lose amount % ≤ 15 table 2 drilling performance item index mud filter loss ml 25 ± 2 apparent viscosity mpa.s 6 ～ 8 drilling fluid filter loss of sample additive 1% ml ≤ 14 apparent viscosity of sample additive 1% mpa.s ≤ 8 shall inflection falling rate % ≥25 c. package transport deposit every three bags in a paper-plastic bag which is sealed by gummed tape, each bag net weight 25 kg±1%. notice to be against leakage. it is non-flammability, non-explosion, non-toxic and harmless. transport management according to non-dangerous product. svchem65.yahoo.com.cn
