水平井和大斜度井中的感应测井响应计算

COMPUTATION OF INDUCTION LOGGING RESPONSE IN HORIZONTAL AND HIGHLY-DEVIATED WELLS

感应测井受井斜影响十分严重，在水平井和大斜度井中，感应测井曲线几乎面目全非．水平井和大斜度井中感应测井响应的正演计算是正确认识这种复杂环境中感应测井响应特征的重要手段，是进行井斜环境影响校正的必要准备，是研究用感应测井曲线探测水平井井眼离最近界面距离的基础，同时也是感应测井理论的新发展．本文将论述水平井和大斜度井中感应测井响应正演计算的理论和方法；分析水平井。

Induction logs are severely influenced by the deviation of borehole,especially in highly deviated and horizontal wells,where they looks fantastic.The forward computation of induction logs in deviated and horizontal wells is a significant way to recognize the behaviors of the induction logs in these situations.It is an imperative preperation for the deviation correction of induction logs,and a fundamentfor the detection of the nearest boundary in a horizontal borehole with induction logs.It is also a new development of the theory of induction logging.In this paPer,the theory of the forward Computation of induction logging response in deviated and horizontal will be discussed. The main features of induction logs of deiated and horizontal wells will be described according to the analysis of the computed logs
