Acoustic velocity log numerical simulation and saturation estimation of gas hydrate reservoir in Shenhu area, South China Sea.

With the increase of the sediment burial depth in depth of 50 to 245 mbsf at site SH2, the porosity presents a decreasing trend except for the abnormality caused by borehole conditions in some intervals, and P wave velocity of forward stimulation (S h = 0) slowly increases from 1743 to 1795 m/s.
