Abstract:

On the basis of the interrelationship of structure and lithology of the trap, the composite traps can be divided into 4 styles, including monoclinal-lithologic trap, anticlinal-lithologic trap, fault block-lithologic trap and nose-lithologic trap. After studying the data of the central structural belt in Shiwu rift,southern Songliao basin, it is found that there are several structural-lithologic composite traps,such as the structure to the west of SN85 well, the structure to the northern SN87 well and North Gujiazi structure. These structural-lothologic composite traps will be the favorable exploration targets in the future.

Key words: structural-lithologic composite trap, style, Shiwu rift
