摘要
示踪流量测井法和集流式测井法是目前环空井常用的测井方法,通过对两种测井方法的技术特性和影响因素分析,提出了环空测井系列优选的依据,得出垂直或斜度较小、井筒周围不含高放射性物质、产量中等的油井应采用示踪流量测井法;斜度大、含水高、产量低的油井则应采用集流式测井法,并在实际应用中见到了良好的效果。
At present radioactive tracer flow log method and confluent-liquid mode log method are common logging ways in annular wells. Through an analysis of the two methods about technological features and factors influenced, it offers an optimum selection evidence for the annular logging series, and indicates that we should adopt radioactive tracer flow log method for producers with vertical or lower deviation, without high radioactive material around the borehole and with modest oil production. Confluent-liquid mode log method will be used for wells with higher deviation, high water cut and low production. The practical application results are good.
