摘要	The calculation of water content of subsurface formations is mainly influenced by the porosity and saturation. Through laboratory tests of core samples of coal seam and its roof and floor, the relations between porosity and compressional and shear wave velocities are statistically set up. Then combined with the P- and S-wave velocities inversed from 3-component seismic exploration, 3-dimensional porosity data of the coal measure strata are calculated. By the lithological-electrical parameters testing results and Archie Formula, the water saturation of subsurface formations is derived. With the methods above, predictions of comparative water content in three coal seams were tried in Huainan Coal Field; with the help of 3D three-component seismic data, well logging and samples tests, quantitative prediction of 3-dimensional water content of the coal seam is realized. Compared with conventional methods such as borehole controlled evaluation, the new method can calculate 3-dimensional water content in a relatively fine and quantitative way, and the method may provide useful references for estimating water content distribution in coal and gas exploitation.
