The utility model relates to the field of oil well logging, in particular to a sectional type experiment scale device which is composed of a plurality of independent hollow cylindrical containers, theend faces of the containers are tightly attached, different containers are used for containing saline water with different resistivity, and underground stratums with different resistivity are simulated in a sectional mode. The hollow simulation wellbore, the container simulation stratum and the hollow are located on the central axis of the container, all the containers are integrated, non-conducting, non-magnetic and transparent materials are adopted, the state of liquid contained in the containers can be observed more conveniently in the experiment process, and when the wellbore is empty, the open hole well logging environment can be simulated. After a whole section of steel sleeve penetrates into the borehole, the steel sleeve can be used for simulating the well logging environment of the cased well; the device can be used for calibrating open hole well induction type logging instruments and cased well induction type logging instruments, and engineering values measured by the instruments can be calibrated.
