摘　　要：汶川地震断裂带科学钻探工程的地层条件十分复杂,岩层破碎,膨胀缩径,不确定因素多,出现多次卡、断、落等孔内事故,但都科学诊断、成功处理。通过优化钻进方法、钻具结构及泥浆体系等多种事故预防措施,最大限度地减少事故发生,保证了科学钻探工程的顺利进行。The formation conditions of Wenchuan earthquake fault scientific drilling project are very complicated. Broken rock formation, lost circulation and borehole shrinkage are encountered frequently. As a result, many drilling accidents, such as drill pipe sticking, drilling pipe breaking, objects dropping and so on happened and were successfully solved. Technical measures for preventing accidents, including scientific diagnosis and optimizing drilling method, drill tool structure and drilling mud system, have been taken to minimize accidents and ensure the smooth progress of scientific drilling project.
