摘要： 中海油服技术中心机电研究所研发的新型旋转井壁取心工具在渤海油田探井作业的成功应用已使此项技术逐步转化为常规勘探技术。文章阐述了该取心工具的技术特点、井下工作参教及其相对火药壁心和钻井取心的优势,总结了其适应的井况及地层条件,同时结合应用实例说明旋转壁心在复杂岩性识别、储层评价、储层含油气性分析等方面所发挥的作用。以岩心试验数据为基准,旋转壁心与岩心的试验数据误差量极小,说明旋转壁心在一定条件下能够代替常规钻井取心。

Abstract: Successful application of the new rotary sidewall coring (R-SWC) tool independently developed by the Electromechanical Research Institute of Technical Center, China Oilfield Services Limited has made R-SWC technology a conventional exploration technology. This paper stated the characteristics, downhole operational parameters, and the advantages contrasting to common SWC and drilling core of the new tool, and concluded its applicable hole conditions and formation conditions. Meanwhile, it presented the importance of the new tool in complex lithology identification, reservoir appraisement, and reservoir hydrocarbon-bearing property analysis with application cases. Core test data showed that the error rate was under control, which indicated that R-SWC could replace drilling core under certain conditions.

Key words: independent research and development, SWC, R-SWC, drilling core
