摘　　要：文章详细介绍了靳39井在鄂尔多斯盆地伊陕斜坡的钻井地质设计和工程设计中的关键技术要点及应对措施。作为一口预探直井,靳39井周围多口井在马家沟组、盒8、山西组等地层中显示出良好的气显示。通过对邻井资料的综合分析,预期该井在古生界可能有多层系复合含气,尽管钻探风险相对较小,但仍需关注地质风险。文章首先概述了区域地质特征,详细阐述了井身结构设计,并提出了不同井段的施工优化技术措施,为后续同类井型的钻探提供了宝贵经验。This paper introduces in detail the key technical points and countermeasures in the drilling geological design and engineering design of Well Jin 39 in the Yishan slope of Ordos Basin.As a pre-exploration vertical well,several Wells around Jin 39 show good gas display in Majiagou Formation,He8 formation and Shanxi Formation.Through the comprehensive analysis of the adjacent well data,it is expected that the well may have multi-layer complex gas bearing in Paleozoic,although the drilling risk is relatively small,but still need to pay attention to the geological risk.The paper first Outlines the regional geological characteristics,elaborates the well structure design in detail,and puts forward the construction optimization technical measures for different well sections,which provides valuable experience for the subsequent drilling of similar well types.
