同位素微球密度和注入水密度的匹配

On Matching between Density of Isotopic Microsphere andDensity of Injected Water

王秀兰等．同位素微球密度和注入水密度的匹配．测井技术，１９９５，１９（３）：１５９～１６３论述同位素吸水剖面测井中合理使用同位素微球密度的重要性。实践证明：颗粒密度大的微球不但对测井资料的质量，而且对注入水井的生产都有影响。（１３１）Ｂａ同位素微球粒密度是根据井下温度、压力条件下的注入水密度值选取的。给出了后者的计算方法和同位素微球出厂粒密度指标的鉴定方法。

Proper isotopic microsphere density is rather important in injection profile log.It has been proved that the sphere with larger grain density not only affects thequality of log data,but also the production of injection well.The grain densityof131Ba isotopic microsphere is selected according to the density of the injected water at downhole temperature and pressure,the equations for the calculation ofwhich is proposed.And how to inspect the grain density of the commercial isotopicmicrosphere is also given.
