摘要: 针对南极地区冰岩夹层井壁稳定风险高的问题，以纳米二氧化硅、硅烷偶联剂、甲基丙烯酸和甲基丙烯酸月桂脂为原料，利用反相乳液聚合法，研制了一种适用于超低温环境的有机/无机杂化封堵剂（GSF），并通过红外光谱仪、激光粒度仪、金相显微镜对GSF的结构进行了表征。结果表明，封堵剂在−50℃低温钻井液中分散性及配伍性良好，随着封堵剂加量增加，钻井液对砂床的侵入深度越低，砂盘的滤失量减少；当加量为5%时，封堵效果最优，侵入深度为7.0 cm，滤失量为76 mL。Abstract: An organic/inorganic hybrid plugging agent GSF has been developed for dealing with the borehole wall destabilization problem encountered in drilling the ultra-low temperature rocks interbedded in the icesheets in Antarctic area. GSF was synthesized using inverse emulsification polymerization method with such raw materials as nano silica, silane coupling agent, methacrylic acid and lauryl methacrylate. Characterization of the molecular structure of GSF with IR spectrometer, laser particle size analyzer and metallurgical microscope showed that GSF has good dispersion performance and good compatibility with other additives in a drilling fluid in −50℃. Increasing the concentration of GSF, the invasion of the drilling fluid filtrate into the sand-bed tester becomes shallower, and the filtration rate of the drilling fluid decreases. At a concentration of 5%, GSF exhibits optimum plugging performance; the depth of invasion by the filtrate is 7.0 cm and the filter loss is 76 mL.
