| 中文摘要:皖含地1井是在和含巢逆冲推覆构造带中段巢湖背向斜构造带部署实施的一口地质调查井。目的在于获取巢湖-含山-无为地区奥陶系-志留系富有机质页岩的各类地质参数，为本区五峰组-高家边组页岩气资源潜力评价及有利区优选提供地质依据。本文主要阐述了皖含地1井的井区概况、钻探施工技术与施工工艺。施工中结合实际情况进行钻井质量控制，在钻进过程中合理调整钻进参数，有效控制钻井顶角，符合地质设计的目的。并对皖含地1井进行台效分析，为后期的钻探积累了经验。 |

| Abstract:Well Wanhandi1 was a geological survey well deployed and implemented in the Chaohu anticline tectonic belt in the middle section of the inrush nappe zone. The purpose was to obtain various geological parameters of Odovic Silurian shale in the Chaohu-Hanshan-Wuwei region， providing geological basis for the evaluation of shale gas resource potential and the optimization of favorable blocks in this region. This paper mainly expounds the general situation of the well site area, drilling techniques and process for Well Wanhandi1, drilling quality control, proper adaption of the drilling parameters during drilling, and effectively control of the borehole inclination, which conforms to the purpose of geological design. Analysis of the rig efficiency is made so as to provide experience for upcoming drilling. |
