云南滇中红层地区抗旱救灾水井钻井方法探讨与成效

Study on Water Well Drilling Method for Drought Resistance in Red Layer Region of Central Yunnan and the Effect

摘要:

在2010年初的西南地区抗旱会战水井施工中，根据当地的施工环境和条件，针对滇中红层采用不同的钻探设备和钻进成井工艺，快速、有效地成井，取得了良好的技术经济效果和重大的社会效益。介绍了在该地区加快钻井速度、提高成井质量的工艺技术方法与施工经验，供今后在类似条件下的钻井工程借鉴。

Abstract:

Based on the construction environment and the conditions, according to the characteristics of red layer of central Yunnan, different drilling equipments and well completion technologies were adopted in the southwest drought resistance at the beginning of 2010. Favorable technically economic effect and important social benefit were gained by fast and effective well completion, drinking water crisis was solved for local people and domestic animals. This article describes the technology methods and construction experience of improving well quality and drilling speed in the red layer of central Yunnan, such experience can be used as reference to the future drilling projects with the similar conditions.
