摘要：
The use of neutron logs to locate the top of the cement around a casing is described. The theory is that presence of liquids in the annulus outside the casing will increase absorption of the neutrons and reduce secondary gamma radiation compared with a cemented portion. An example neutron log is interpreted to show the cement top.
