Multiple linear regression equation between LST and brightness temperatures of AVHRR channels 4 and 5 was almost at the significant level (p＜0.05), and the level was not improved by adding brightness temperature of AVHRR channel 3 as a regressor. Path analysis is a statistical technique that partitions correlations into direct and indirect effects, and differentiates between correlation and causation. The results of path analysis showed that the direct effects and indirect effects of brightness temperatures of AVHRR channels 4 and 5 to LST were strong, respectively, the direct effect and indirect effects of brightness temperature of AVHRR channels 3 to LST were weak. These implied the brightness temperatures AVHRR channels 4 and 5 should be involved in retrieving LST.

多元线性回归分析结果表明，土地表面温度与AVHRR第4、5波段亮度温度间的回归方程接近5％的显著水平；通径分析的结果表明，AVHRR第4、5波段的亮度温度对土地表面温度的直接作用和间接作用均较强，而AVHRR第3波段的亮度温度对土地表面温度的直接作用和间接作用均较弱，因此，在反演土地表面温度时必须同时考虑AVHRR第4、5波段的亮度温度。

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.
