摘　　要：为了提高钻遇断层、大裂缝、溶洞及流水溶洞情况发生的失返性漏失堵漏的成功率,研制了一种新型膨大管柱堵漏工具。该工具直接送达漏层,使堵漏材料在受限空间内凝固,并在井眼轨迹穿过的通道上建立所需体积和强度的堵塞,从而解决失返性漏失问题。介绍了该堵漏工具的结构组成、选材、制造工艺和使用方法。In order to improve the plugging success rate when drilling to faults, large cracks, caves which lead mud loss, a new type of swelling pipe plugging tool was developed. The tool can be sent directly to the leakage layer and the plugging material solidifies in the confined spaces, the formed plug with required volume and intensity through the channel in the well trajectory will solve the no-return loss problems. The paper introduces this plugging tool about its structure composition, material selection, manufacture technology and the using methods.
