摘要
介绍了姜堰溱湖风景区地热1井的岩性特征、施工技术和成井工艺。该井采用塔式钻具结合,有效地提高了钻井效率又防止了孔壁塌坍、掉块。
The lithologic properties, construction technology and well formation technique are presented in the text. Combining with the towered drilling tools,the drilling efficiency is improved,and the risks like collapse and drops of the wall are prevented as well. The successful exploitation of Qinhu-1 may ensure the technology of geoheat exploitation in North Jiangsu.
