| 中文摘要:钻遇渗透性漏失地层、破碎地层及低承压地层时，通常加入随钻封堵材料以防止钻井液漏失、提高孔壁稳定性和地层承压能力。深井高温地层及高温地热、高温干热岩钻探，遇到上述复杂情况时，需采用抗高温封堵材料。本文介绍了我国近年来抗高温随钻封堵材料研究与应用的进展情况，包括由桥接堵漏材料组成的抗高温随钻堵漏剂、膨胀型聚合物堵漏剂、超低渗透处理剂及弹性石墨等新型抗高温随钻堵漏材料。分析了4种抗高温随钻封堵材料的组分及其堵漏原理，并对抗高温随钻封堵材料的研究方向提出了建议。 |

| Abstract:In order to prevent lost circulation, increase the borehole wall stability and formation pressure, plugging material while drilling is usually added while drilling in permeable leakage formation, broken formation and low pressure formation. Especially in high temperature deep well, high temperature geothermal well and high temperature hot dry rock drilling, high temperature resistant plugging material must be added to drilling fluid. In this paper, the new progresses of high temperature resistant plugging material while drilling are introduced, including loss circulation agent while drilling based on bridge loss circulation material, expansive polymer plugging agent and ultra-low permeability agent. The composition and plugging mechanism of different high temperature resistant plugging materials while drilling were analyzed and the research direction of high temperature resistant plugging material while drilling was pointed out. |
