摘要
针对国内首例椭圆竖井施工实践，进行了竖井断面选取的经济技术对比分析，详述了竖井施工流程，对类似竖井延伸施工具有重要参考价值。
In light of the first construction example of oval vertical well, an economic and technical comparison analysis is made on the selection of the section of the vertical well, in which vertical well construction processes are described in details, being very referential to similar wells.
