| Abstract: | The steel casing in oil well is considered as a large diameter wave guide. And it is possible to measure the water hold-up of mixed fluid in the casing using electromagnetic wave propagation method. This paper produces a wave guide method analysing electromagnetic wave propagation properties of guided wave system formed by oil well casing, and inspects the possibility of the method using numerical and physical modeling results. It is shown that this method possesses some special advantages and has bright applying prospect. |
