| 英文摘要 | By using seismic, sonic logging and geothermal data the distribution characteristics of gas hydrates in Dongsha region north of South China Sea are studied. Bottom simulating reflectors (BSR) and amplitude blanking zone are discovered in seismic profiles. And high-velocity interval and velocity reverse are distinguished in sonic logging curve. The BSR depth is compared with thickness of gas hydrates stability zone from thermal gradient data. The depth of BSR is in agreement with that obtained at ODP site 1144 and 1148, which are 654 and 475 meters below sea floor, respectively. The top of amplitude blanking zone may be related with that of gas: hydrates-bearing strata in adjacent region of ODP site 1144 which is about 450 meters below sea floor. |
