摘要
煤炭地质勘查水文地质勘探孔一般洗井方法有活塞洗井、压缩空气洗井、酸化洗井、多磷酸盐洗井、液态二氧化碳洗井、水泵抽水洗井等。根据近两年的钻井施工管理经验,总结了煤炭地质勘查水文地质勘探孔的一般洗井方法及流程。
There are well-flushing by piston,by compressed air,by acid,by polyphosphates,by liquid carbon dioxide and by pump etc..For the well-flushing methods of hydro-geological exploitative hole in coal geological exploration,according to recent two year's management experience of drilling construction,the paper summed up general well-flushing methods and process of hydro-geological exploitative hole in coal geological exploration.
