| 中文摘要:甘肃省文县阳山矿区地质构造复杂，地层破碎蚀变强烈，多层位漏失，钻探施工漏失现象普遍。在研究地层漏失机理的基础上试验应用了聚合物凝胶堵漏技术。ZK2232孔的现场应用表明，聚合物凝胶堵漏剂与其他惰性桥堵剂配合使用，能很好地解决钻进过程中的恶性漏失问题，堵漏效果较好。在堵漏施工中，聚合物凝胶堵漏不受漏失通道的限制，能够通过挤压变形进入裂缝和孔洞空间，最终达到封堵漏层的目的。 |

| Abstract:Gansu Yangshan mining area geological structure is complicated, broken strata alteration strong, multi layer leakage, drilling leakage loss is a common phenomenon. On the basis of in-depth study of the mechanism of formation leakage, the polymer gel plugging technology is explored and tested. In the construction, polymer gel plugging is not limited by the leakage passage, which can enter the space of cracks and holes, and ultimately achieve the purpose of sealing leakage. In ZK2232 field application shows that the use of polymer gel plugging agent and other inert bridging agent can be used to solve the leakage of the drilling process, and the effect is better. |
