Drilling design and construction of Well Mengsudi-1 in Yingen-Ejinaqi Basin
-
摘要: 蒙苏地1井是中国地质调查局部署在银额盆地艾特格勒凹陷的一口大口径重点油气地质调查井,根据该区块地层地质概况和钻井施工技术难点,从井身结构、钻具组合、钻头选型和钻进工艺等方面对蒙苏地1井钻井工程进行了优化设计。综合采用 “简化井身结构+非常规钻具组合+常规钻头选型+强抑制性泥浆”的钻井技术方案,解决了中生界巴音戈壁组和二叠系上部地层的高硬度、可钻性差、裂缝构造易井斜及井壁失稳等一系列难题,顺利完成了该井的钻井施工任务。该井完钻井深2763.66 m,完钻口径215.9 mm,平均机械钻速3.51 m/h,成功揭示了中生界和石炭-二叠系岩石组合特征及含油气性,优质、高效、零事故完成各项目标任务。Abstract: The Well Mengsudi-1 is a large-diameter key oil and gas geological survey well deployed by China Geological Survey in the Aaitegle Sag, Yingen-Ejinaqi Basin. In view of the geological conditions and technical difficulties in drilling in this block, optimization has been made for the drilling works of the Well Mengsudi-1 from the aspects of the wellbore structure, the drilling assembly, bit type selection and drilling technology. A drilling technical plan with the combination of “simplified wellbore structure+unconventional drilling assembly+conventional bit selection+strong inhibitory mud” was adopted and eliminated a series of problems such as high hardness, poor drillability, easy well deviation and wellbore instability in fractures in Mesozoic Bayingebi Formation and Upper Permian, leading to the successful completion of the Well Mengsudi-1. Drilling of the well was completed at 2763.66m with the diameter of 215.9mm, and the average drilling rate of 3.51m/h. The well successfully revealed the characteristics of Mesozoic and Carboniferous Permian rock assemblages and oil and gas potential, meeting various objectives and tasks with high quality, high efficiency and zero accidents.
