The log data of Samandepe gas field in the Amu Darya Right Bank of Turkmenistan are old in logging suites, limited and inconsistent in logging items between early exploratory wells and later development wells. Based on the correlation of different log data, the suitable log data are selected from the available logging suites to build up a mathematical statistical model of artificial fitting acoustic curve. The non-linear correction of neutron and gamma ray data was performed to ensure the relative rationality and uniformity of log interpretation.
