新型旋转井壁取心工具在渤海油田的应用

The Appliation of A New Rotary Wall Coring Tool in BoHai Oilfield

渤海油田自主研发的新型旋转井壁取心工具在渤海探区的成功应用使得此项技术逐步转化为常规勘探技术。阐述了新型钻井取心工具的技术特点,井下工作参数及旋转壁心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、储集层评价、储集层含油气性分析方面发挥的作用。以岩心试验数据为参照基础,旋转壁心与岩心的试验数据误差量级小,说明旋转壁心在一定条件下能代替常规钻井取心。

An independently developed new rotary wall coring tool was successful used in Bohai Oilfield,by which it has been gradually transferred into a conventional exploration technique.The technical characters of the coring tool,down hole operational parameter and the its advantages were described.Well conditions and strata that it could be used were summed up.At the same time,the fundtions of lithologic recognition,reservoir evaluation and as well the evaluation on its oil-bearing property were described in combination with application examples.Based on the study of test data,it shows that the data of rotating wall coring and core analysis are less errors,it indicates that the rotating wall coring can be used to replace the conventional coring under a certain condition.
