| 中文摘要:具有中生界海相和海陆相交互沉积、且被多次构造运动改造后的三江盆地，其覆盖层均为软塑地层，并且厚度较大；针对三江盆地厚覆盖层软塑地层保直钻进施工存在的难点，从钻进方法、井身结构、钻井液护壁、工艺措施等方面进行研究，分析得出适合于在三江盆地软塑地层不下套管的情况下，实施保直取心钻进的技术措施，并且在生产实践中解决了钻进技术难点，取得较好的经济效果。 |

| Abstract:Sanjiang basin, with the Mesozoic marine and land sea interaction deposition and after the transformation of multiple tectonic movements, its covering layer is thick soft-plastic formation. According to the stratigraphic characteristics of Sanjiang basin and drilling difficulties in drilling construction, the study was made on drilling methods, borehole design, flush fluid and process measures, the technical measures suitable for highly straight drilling were carried out without casing in thick overburden strata of soft plastic formation in Sanjiang basin, and the drilling difficulties were solved in the practice with good economic effect. |
