注入剖面测井存在的问题及解决途径

Existential problems in injection profile logging and its solving methods

注入剖面测井在油田开发过程中的应用非常广泛,但在放射性同位素示踪注入剖面测井中存在很多问题,例如同位素沾污、窜槽、漏失及井底堆积等,严重影响了资料的解释与应用。通过对近几年孤岛油田注入剖面资料的分析,总结了孤岛采油厂及其它油田在控制和消除同位素沾污、窜槽以及同位素漏失方面所做的工作,阐述了注入剖面测井的发展,建议提高注入剖面测井资料的可靠性。

At present,injection profile logging is widely used in oilfield development,but there are some problems in radioactive isotope tracer injection profile logging,such as isotope staining,channeling,leakage and bottom hole accumulation etc.,severely influencing the logging data interpretation and application.This paper analyzes the injection profile logging data in recent years,summarizes the work of Gudao Oil Production Plant and other oilfields how to solve the above problems,and makes a brief statement on future development of injection profile logging.
