They show distinctively different logging response for the high conductive formation layer and the low conductive cementlayer.
对高电导地层，低电导水泥环有明显的测井响应；

Correction system for resistivity logging in cased hole has been established in paper, including on condition of non-uniformity casing, formation having shoulder, cementlayer.
文中建立的套管井电阻率测井校正系统，包括套管非均匀性、地层上、下围岩和水泥环的校正。

Research results show:(1)the original temperature field of cementlayer surface were quickly destroyed in initial coil pipe leakage, while the changes of floor surface were weaker;
