    摘要
  • 摘要: 抗高温改性淀粉FSL综合性能的充分发挥得益于性能优异的聚合单体、单体分子量的控制、位阻基团的贡献以及吸附水化基团的作用，为改性淀粉提供了性能保障。为了验证抗高温改性淀粉FSL的抗温性能，将该产品应用于CSH1井和AF1井高温井段。CSH1井应用井段为8154~8380 m，井底温度为187℃。在加入2%产品充分循环后，钻井液黏度基本保持不变，且高温高压滤失量明显降低。AF1井应用井段为5713~5810 m，井底温度146℃。在加入1%产品充分循环后，高温高压滤失量有较大降低，且对流变性无影响。在2口井的高温井段均表现出优异的降高温高压滤失性能及高温稳定性。抗高温改性淀粉FSL系列产品表现良好的实际应用效果，具有广阔的应用前景。

     

    Abstract: 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.
