大孔道地层注水剖面测井技术

同位素示踪载体法是目前国内各注水开发油田普遍采用注水剖面测井方法，但在现场测井应用中，注水地层孔隙结构的变化使示踪载体粒径的选择很困难，造成的同位素测井施工中无法准确地录取大孔道地层的注水剖面资料，通过对大孔道地层同位素注水剖面测井失败的原因分析，提出了一套针对大孔道地层的注水剖面测井方法，较好地解决了存在大孔道地层注水剖面测井资料的录取问题，取得了较好的测井成果。

Logging Method for Water Injection Profile in Macropore Formation

At present, isotope tracer carrier method is universally used for testing water injection profile in waterflooded development China oilfield. But it is difficult to select proper grain size of tracer carrier in field logging because of variations of pore structure in waterflooded zone. As a result, it is impossible to accurately obtain water injection profile data of macropore formation during isotope tracer logging operation. In this paper, a set of logging method for water injection profile is addressed after analyzing the cause of logging failure in macropore formation. This method solves the problem of data acquisition in water injection profile logging in macropore formation and gets better logging result.
