Product Description

GTD95_200C through casing resistivity logging tool selects flexible connection mode and is pushed to the well wall through special hydraulic drive in casing, and it needs no well washing and scraping before measuring. Electrode of return circuit is connected to the casing of adjacent well, making current line perpendicular to the casing of original well, reducing the effect of surrounding rock, enhancing longitudinal resolution, deepening the probing depth of tool. To decrease the effect of nonuniformity of casing thickness on measuring result, the tool chooses the power supply mode of top and bottom electrode in turns to acquire formation resistivity.

Features

  • It measures in casing without well washing and scraping.

  • It has monitoring software for pushing quality, the measuring data is true and reliable and consistent with the data of borehole resistivity logging.

  • It has no requirement on formation porosity and salinity.

  • Investigation radius is more than 100 m.

  • Investigation process has no pollution.
