  • The full play of the performance of the high temperature modified starch FSL benefits from the monomers used to produce the starch. The molecular weight of the monomers, contribution of the steric hindrance groups and the strong effect of the adsorbed hydrational groups all provide performance guarantee to FSL. FSL has been used to drill the high temperature sections of the well CSH1 and AF1 to verify its high temperature performance. The section of the well CSH1 in which FSL was used was drilled from 8145 m to 8380 m, and the bottom hole temperature was 187 ℃. The drilling fluid, after treatment with 2% FSL and full circulation, maintained its viscosity at a level that was almost the same as before, while its HTHP filtration rate was reduced obviously. The section of the well AF1 in which FSL was used was drilled from 5713 m to 5810 m, and the bottom hole temperature was 146 ℃. After the addition of 1% FSL into the drilling fluid and full circulation, the rheology of the drilling fluid was not apparently affected, while the filtration rate of the drilling fluid was greatly reduced. FSL showed its superior HTHP filtration control performance and high temperature stability in drilling the high temperature sections of the two wells. The excellent performance of FSL in field application has proven its broad application prospect. Another real environmentally protective and high temperature modified starch that is in development will technically support the green development of drilling industry.
