GEOLOGICAL MODEL AND PREDICTION FOR FAVORABLE AREAS OF NATURAL GAS HYDRATE IN SHENHU AREA

In order to deal with the complex sforming factors and tough prediction problem of natural gas hydrate, this paper analysised the sedimentary characteristics, sensitive seismic attributes and physical properties of the natural gas hydrate bearing zone by BSR tracing, based on integrating 3D seismic data, well log data and core data in the Shenhu Area, North Slope of the South China Sea. It is tound that the distribution of natural gas hydrate was restriclto within certain sedimentary facies, seismic attributes and physical properties. Reasonable method was selected to establish sedimentary facies, seismic attributes and physical models according to the actual data. with the three kinds models, favorable areas in sequence V was predicted which was mainly distributed between south well S2, S3 and well S5. Few was distributed around wells S4.
