| 中文摘要:唐山市丰南区ZK1地热井终孔深度3204.8 m，成井深度较深，揭露地层情况较为复杂，采用“四开”井身结构。施工过程中，根据钻遇地层情况的变化，及时调整钻具组合及钻进、钻井液等参数，降低了由于地层变化较大而产生漏浆、掉块、井壁垮塌等造成埋钻、卡钻的施工风险，保证了孔内钻探施工安全及成井质量，为唐山地区相同或此类地层的地热井勘探施工提供了成功经验。 |

| Abstract:The termination depth of ZK1 geothermal well in Tangshan is 3204.8m with “four section” well structure, the revealed formations are complicated. In the construction process, according to the different formations encountered, the BHA and the parameters of drilling and drilling fluid were adjusted timely to reduce the construction risks of drill rod burying and sticking caused by mud leakage, block falling and wall collapse due to large formation changes; the safety and quality of well drilling and completion construction were ensured. This project provides successful experience for geothermal well construction in the same or similar formations in Tangshan area. |
