摘　　要：在正钻开发井中发现设计外新油层是一项勘探开发各方都十分关注的工作,对现场录井具有重要意义。围绕这一内容,通过对不同类型油气藏的分析,指出了各类油气藏发现新油层的主要目标及途径,对现场发现设计外油层的录井经验进行了总结,阐述了发现设计外油层应把握的5个重点环节———做好钻前预测、取全取准资料、加强随钻分析、精细解释评价和与老井复查相结合补充完善随钻动态分析,并应用部分实例进行说明。强调指出精细解释评价是重点环节的核心,而精细解释评价的关键是做好“差别化”和“综合化”分析。Finding the new oil zone out of planning during drilling a development well is an interest work concerned with by both parties of the exploration and development and has significant meaning for well-site mud logging. In view of it, the authors pointed out the main targets and ways for finding new oil zones in various oil and gas reservoirs, summarized mud logging experience for finding oil zones out of planning on well-site with part of the examples, and stated 5 key links that should be grasped in finding oil zones out of planning, which were performing the pre-drilling prediction, getting perfective and accurate data, enhancing analysis while drilling, carrying out the fine interpretation and evaluation, and replenishing and perfecting dynamic analysis while drilling with old well reexamination. The paper emphasized that the fine interpretation and evaluation were the key points and doing the work well should insist on the analysis of “difference”and “composition”.
