摘要
The comparative analysis of sand genetic mechanism and difference between the meandering river delta and braided river delta is conducted. It is suggested that the hydrodynamic condition, transport capacity and erosion ability of the braided river delta are more powerful and better sand interconnectivity than the meandering river delta, by which three sand genetic geologic models are developed, and the corresponding three traps and their composite types are studied by using different exploration approaches. It is concluded that the lithologic trap corresponding to the isolated sand model of the upper sub-member of second member of Sangonghe Formation could be the main target for petroleum exploration in Block-1 of central Junggar Basin.
