琼东南盆地天然气水合物成矿远景

Abstract

Abstract: The latest survey and study in the Qiong Dongnan basin found a lot of seismic reflection interfaces with suspected BSR (bottom simulating reflector) features, but the BSR features aren't typical. Accurate identification of BSB is very important for evaluation of gas hydrates. To evaluate gas hydrates is a challenge where BSR features aren't obvious. We conducted the correlative analyses between the gas hydrate occurrence and tectonics, sedimentation, and origin gas. All evidences indicate that in the central depression belt of the Qiong Dongnan basin, a large number of gas chimneys and the shallow sea bottom near the seabed should be the key target areas for the development of natural gas hydrates. This study will help to find out the conditions of the mineralization of gas hydrates, and contribute to the resource assessment of gas hydrates.

Key words: gas hydrate, hydrocarbon source rock, gas migrate passage, bottom simulating reflectors, Qiong Dongnan basin
