Abstract
A quinary copolymer filter loss reducer for use in high temperature and high salinity environment has been developed with AM, AMPS, DMDAAC, DMAM and SAS as monomers through water solution copolymerization using redox initiation system. The optimum synthesis conditions were determined laboratory experiment. The synthesized filter loss reducer was characterized with IR spectrometry and thermogravimetry, and was evaluated for its properties in water base drilling fluid. The experimental results show that the synthesized quinary copolymer is resistant to high temperature to 180 ℃, to salt contamination to saturation, and to calcium contamination to 1.25％. Fresh water base mud, saturated saltwater base mud and base mud containing 1.25％ treated with 2％synthesized quinary copolymer had filtration rate of 6.4 mL, 15.6 mL and 7.2 mL, respectively after being aged for 16 hours at 180 ℃. Compared with similar additive Driscal, the synthesized quinary copolymer is more effective in resisting high temperature, salt contamination and calcium contamination. The filtration rates as mentioned above are only about 50％ of the same base muds treated with 2％Driscal, respectively.关键词
