摘要
针对大庆油田持续开发给注水剖面测井带来的新问题,采用新工艺制造了适用于低注入量井的注入剖面测井;开发了5参数组合测井仪,用管内流量、静态井温、流动井温与放射性同位素示踪资料综合解释,提高了资料的准确性和可靠性;新研制的高可靠性脉冲氧活化测井仪和新开发的示踪相关流量测井技术能基本满足对注聚合物井进行注入剖面测井的需要。大庆油田现已规模应用了注入剖面测井新技术,并总结出了优选应用方法。
Radioisotope microball tracer which was produced by new process is applicable to injection profiling in low injection rate wells. Five-parameter combo logging tools were developed, which enhance accuracy and reliability of log by integrating interpreting flowrates inside tubing, shut-in and flowing well temperatures and tracing results. Reliable impulse oxygen-activation logging tools and a tracer logging method with correlation arithmetic were developed to meet the need of profiling polymer injectors. These new techniques are widely used in injection profile logging at Daqing oilfield.
