| 中文摘要:安徽铜陵铜金多金属矿集区在以往的钻探生产中施工难度大,溶洞、裂隙发育，导致钻孔施工中冲洗液漏失严重，施工周期长，成本高。通过配制沥青球对ZK6616孔冲洗液漏失的灰岩及大理岩裂隙地层进行堵漏，取得了良好的效果，降低了冲洗液的消耗，提高了钻探效率。与此同时，对采用常规堵漏手段无法封堵的漏失地层，也有着良好的借鉴作用，沥青堵漏的研究对漏失地层钻探施工有着重要的意义。 |

| Abstract:The drilling construction was difficult in Tongling copper-gold polymetallic ore concentration area of Anhui, where caves and fissures developed; long construction period and high cost were caused by serious drilling fluid loss in the drilling process. But good result was achieved by the preparation of asphalt balls which were used in ZK6616 hole for limestone and fractured marble formations plugging. This case can be a good reference to those formations where the conventional plugging means have no effect; and at the same time, it has an important significance for the loss zone drilling. |
