摘　　要：深海钻探往往伴随着高温、高压,对钻井用堵漏材料提出了新的要求。首先通过对颗粒状、纤维状和片状堵漏材料的耐高温筛选,制作了HTD-3型高温堵漏材料。然后使用DL-3A型高温堵漏评价仪器对该堵漏材料的抗温、承压和封堵性能进行了测试,利用SEM电镜扫描对堵漏材料架桥情况进行了观察和分析,最后以5%梯度浓度进行了配伍性实验。测试结果表明,HTD-3型高温堵漏材料除对钻井液密度影响稍大外,对钻井液其他基本性能影响较小,在该材料中,不同级配的颗粒状材料完成了架桥,纤维状和片状材料完成了充填,形成了强度较高的封堵墙。通过实验证明:HTD-3型高温堵漏材料不仅有着较好的抗温、承压能力,还有较好的封堵效果。HTD-3型高温堵漏材料的研制为未来深海钻探堵漏提供了一种可行的选择。Deep sea drilling is often accompanied by high temperature and high pressure,which puts forward new requirements for plugging materials for drilling.The HTD-3 high temperature plugging material was produced through the high temperature resistance screening of granular,fibrous and flaky leakage plugging materials.Then,the DL-3A high temperature plugging evaluation instrument was used to test the temperature resistance,pressure bearing and plugging performance of the plugging material.SEM was used to observe and analyze the bridging condition of the plugging material.Finally,the compatibility test was carried out at 5%gradient concentration.The results show that the HTD-3 high‑temperature plugging material has some impact on drilling fluid density,but has little impact on other basic properties of drilling fluid.In this material,granular materials with different sizes completed bridging,fibrous and flaky materials completed filling,forming a high‑strength plugging wall.HTD-3 high‑temperature plugging material not only has a good temperature bearing and pressure bearing capacity,but also has a good sealing performance with plugging effect.The development of HTD-3 high temperature plugging material provides a feasible choice for deep‑sea drilling plugging in the future.
