应用地化录井和P-K分析技术综合评价水淹层的探讨

随着油田开发工作的不断深入,老油田综合含水率越来越高,采用常规分析手段对油层水洗程度、水淹状况,剩余油分布的定量研究已不能满足要求。针对这一情况,该文采用地化录井和P-K分析技术对水淹层进行了综合评价,对相关分析数据的处理作了较为详尽的介绍,并结合老油田水淹层分析实例,阐述P-K分析和地化录井技术在水淹层评价方面的作用,拓展了地化录井及P-K分析技术的应用范围。

Multiple evaluation of water-out zone by applying geochemical logging and P-K analysis

With the oil exploration developing,water cut in aged oilfields becomes higher and higher.It is difficult to meet the needs of quantitative research for water-out degree,status and remaining oil distribution with conventional analysing means.According to such conditions, the paper evaluated water-out zones comprehensively by using geochemical logging and P-K analysis technique, introduced the process of related analysing data,stated the role of P-K analysis and geochemical logging in water-out zone evaluation with aged oilfields examples.It has expanded the application range of geochemical logging and P-K analysis.
