In the practical operation of oil and gas exploration, the trap assessment is multi-sample,only limited data are obtained, plus the complexibility of the geological conditions, all these make the geological assessment of traps uncertain assessment model.

Application of gray correlative analysis to structural trap assessment in early exploration has succeeded in solving the problem of trap optimization in the periblock of relatively low degree exploration of Daqing exploration area and shortening the cycle of exploration.

Reservoir prediction and trap evaluation in North Jingbei area;

BP neural networks in trap evaluations in south-west part of Jianghan basin;

Integrated 2D seismic interpretation and trap evaluation on the western block of Mahuang Mountain;

Properties of geometry and kinematics related to hydrocarbon traps in Qiulitag anticline zone of Kuqa Depression;

The objective of hydrocarbon traps exploration is hankering for maximum profit.

Based on the reinterpretation of seismic profiles and compilation maps which have already been obtained in the strdy area, the hydrocarbon traps in this area can be classified into three types and ten subtypes.
