鲁东地区地热深水井施工工艺探讨

Discussion on construction technology of deep geothermal wells in eastern Shandong

针对山东省鲁东地区地热赋存地层的特点以及在该地区多年的施工经验,提出了在该地区进行地热深水井施工时采用气动潜孔锤钻进与传统的回转钻进工艺相结合的施工方法,从而达到两种工艺都能发挥自身长处,弥补对方不足,实现大幅度降低生产成本,缩短成井周期,提高生产效率的目的。对在类似地区钻井具有很好地借鉴和推广价值。

according to the characteristics of the geothermal occurrence in eastern Shandong and many years of construction experience in the area for, put forward the construction of geothermal deep wells in the area when using the way combined the pneumatic DTH drilling with the traditional rotary drilling in the construction process,which give play to the advantages of two kinds of technology, compensate for the other discharge, greatly reduce the production cost, shorten the drilling cycle, and improve the efficiency of the production. It can be used for reference in other similar areas.
