| 摘 要： | 介绍了浩布高矿区复杂地层钻进中所采取的护壁堵漏技术措施。根据岩层及孔深情况采用了套管护壁堵漏、冲洗液护壁堵漏、水泥封孔护壁堵漏等措施,在实际工作中均收到了较好的效果。套管护壁堵漏简洁、护壁安全可靠;冲洗液护壁堵漏所用的人工钠土低固相泥浆对孔内坍塌、掉块具有较高的抑制功能;水泥封孔护壁堵漏效果好。套管护壁堵漏及水泥封孔护壁堵漏为绳索取心使用无固相钻井液钻进创造了条件,能有效地提高钻进效率。施工中根据钻孔实际情况所采取相应的堵漏措施,收到了良好的效果。

| Abstract: | The paper introduced the wall protection and leakage control technical measures for drilling in the complex formation of Haobugao mining area.According to the rock formation and the hole depth,wall protection and leakage control by casing,flushing fluid and cement sealing were adopted with good effect.Casing was safe and reliable,manual sodium soil low-solid mud has high inhibition function to downhole collapsing and block-falling,and cement has good sealing effect.Casing and cementing created favorable conditions for wire-line coring drilling with solid free drilling fluid and improved drilling efficiency. |
