薄层深侧向测井仪

王德贵，李振芬，褚霞光，丁柱．薄层深侧向测并仪．测井技术，１９９４，１８（５）：３７８～３８３薄互层剖面的合理评价要求电法测井具有纵向高分辨率和径向深探测范围。这是长期以来没有解决的矛盾，薄层深测向测井使这一难题得到初步解决。经测井资料分析表明其分辨率达０．１ｍ、探测深度与深三侧向相当；可用于确定岩性，扣除储集层中的钙质、泥质夹层，准确地划分有效厚度，是判断水淹层、评价储层参数的较好方法。本文就该仪器参数、指标，研制技术要点及依据作了介绍。

Thin Bed Deep Lateral Logging Tool.

The evaluation of thin interbeded profile needs high vertical resolution and deep radial investigation from electrical log. However the trade-off between the two factors has not been obtained for a long time. Thin bed lateral logging tool has made it possible. Its vertical resolution teaches 0.1m and depth of investigation is equivalent to Deep LL3. It can be used to identify lithology, deduct calcium and shale interbeds, and thus determine the efficient thickness of the reservoir. It is a good method to locate water-flooded formation and to evaluate reservoir parameters. The tool specifications, performance and technical considerations are given in the paper.
