When the source, reservoir and seal conditions are available, the hydrocarbon potential of flower structure is superior to that of other structural styles because flower structure not only controls the distribution of petroleum accumulations, but also the site of stress release in the strike-slip fault is usually the s.

Branchs of the fault and aruond them appear flower structures, positive inversion structures and buried hill structures.

This paper,using 3D seismic information and well log data,combined with regional geological features,presents the distribution characteristic of this fault zone and suggests that such a fault is characterized by strike-slip nature flower structure,riband effect,crushed zone and volcanic rock body leap,etc.

Depositional genesis of Anpeng structural nose and fractures distributed in Anpeng deep zones;

A series of techniques are presented for reservoir prediction of structural nose,it uses seismic attribute technique,neural networks to predict the reservoir parameters and log-constraint inversion technique,the sandstone bodies and the hydrocarbon distribution of reservoirs.

The hydrocarbon reservoirs discovered in Biyang Depression at present are circularly distributed around source depressions,where many radioactively shaped nose-like structures are developed,its scale is in proportional with that of hydrocarbon enrichment.

The paper discussed the controlling factor and concentration rule of N1s reservoir genesis from structure,sedimentation and fault and resulted in following knowledge: ①low-amplitude nose-like structure dominantly controls the concentrati.
