对异常高压层厚度划分问题的探讨

通过对喇嘛甸油田800多口聚合物井、更新井的厚度划分及对15口井的异常高压层处理的实例，根据异常高压层在电测曲线上的反映特征，准确地将异常高压层识别出来，并采用本井上下相似层对比法、周围邻井砂体预测分析法、新老标准相结合法等综合分析判断方法，正确地划分异常高压层的厚度，将漏划或少划的厚度补划上。给后续的油层对比、水淹层解释、射孔方案的编制及动态、开发综合方案的调整提供准确的基础数据，并为套管损坏的防治、新钻井的异常高压层厚度解释提供了可借鉴的依据。

A Study on the Question of Thinkness Divided for Abnormal High Pressure Layer

According to the result of material of thickness delineate through more then 800 polymer wells and renewal wells include material of abnormal high pressure well delineate,this paper stresses expounding how to judge the abnormal high pressure layer while explaining thickness in well logging, and correctly divides the thickness question of abnormal high pressure layer, providing some basis for the abnormal high pressure layer thickness of new well .
