摘　　要：高分辨率阵列感应(HDIL)测井技术克服了常规电阻率测井纵向分辨率低、探测深度较浅和不能解释复杂侵入剖面及划分渗透层能力较差等缺点,采用多频率阵列测量和软件数字聚焦等技术并经过趋肤影响、井眼、井斜影响等环境校正后,得到3种纵向分辨率、6种探测深度的电阻率测井曲线;时运用一维、二维反演技术准确确定地层真电阻率、冲洗带电阻率及侵入深度,从而对侵入剖面进行直观形象的描述。重点介绍高分辨率阵列感应测井在大港油田储层评价中的实际应用效果。High definition induction logging technology overcomes many defects that conventional resistivity logging tools have, including low vertical resolution, shallow depths of investgation, non-interpreted complex invasion profile and difficult identification of the permeable zones. It adopts multi-frequency array and software focusing technology to achieve three kinds of vertical resolution matched curves and six curves of different depths of investgation after applying skin effect, borehole and dip effect corrections. It can also determine other curves such as the formation true resistivity, flushed zone resistivity, the length of invasion by using 1D and 2D inversion, so the invasion profiles are seen clearly and directly. Effective results of reservoir interpretation and evaluation in Dagang Oilfield are detailed.
