双频介电测井技术在河南油田的应用

The application of dual frequency dielectric logging technique in Henan oilfield

双频介电测井通过测量介质的介电常数,能更好地消除矿化度对测井的影响,从而增强淡水水淹层、低阻层、高阻水层的解释精度,文章给出双频介电资料在河南油田的应用实例,并与常规电阻率解释结果相比较,反映出双频介电测井技术在油田开发后期或地层水矿化度未知地区的优越性。

Dual frequency dielectric logging can measure the dielectric constant of medium. Because it can eliminate the effect of salinity to log, it will improve log interpretation of fresh water flooding layers, low resistance layers and high resistance water layers. The paper gives a practical application of dielectric logging data in Henan oilfield. By comparing with general resistance logging interpretation, the advantage of dielectric logging technique is reflected.
