摘要:
油田开发进入中后期,准确掌握注水井各小层的吸水状况能够为油藏综合调整,挖替增效提供可靠的依据。同位素吸水剖面测井已愈来愈不满足实际生产的需求,采用电磁流量计与同位素示踪吸水剖面组合测井能很好地解决诸如地层大孔道以及注聚合物等注入剖面测井难题。在分析测井过程的基础上,提出了多参数组合吸水剖面测井资料解释方法。实例应用表明,多参数组合吸水剖面测井较传统的同位素吸水剖面测井能有效地解决放射性沾污、大孔道等难题,具有良好的应用前景。

Abstract: In the middle and late stage of oilfield development,it would provide reliable bases for overall adjustment of oil reservoir and increasing efficiency to know the water injection of each sub-layer in injection well accurately.Isotope water-injection profile logging couldn't conform to the requirements of producing increasingly.However,combing the electromagnetic flow meter and isotope tracer injection profile logging could solve those injection profile logging problems such as formation of high capacity channel,polymer injection,etc.Based on the analyses of the logging process,a new method to interpret the data of the multi-parameter water-injection profile combination logging was proposed.Practical applications indicate that multi-parameter water-injection profile combination logging can resolve those problems including radioactive contamination,formation of high capacity channel,etc.much better than the traditional isotope injection profile logging.Thus,this logging technology has a good application prospect.
