This paper uses a large amount of dynamic and static data which are obtained in the process of development in Hailaer burial hill reservoir,to demonstrate migration rules generated from hydrocarbon along unconformity surface,faults and sandbody,and understand control factors for hydrocarbon migration dominant channel.

The concept of dominant channel of waterflooding is put forward, a streamline based numerical simulating technique is used to study the effect of the dominant channel attribute on reservoir development.

Based on the physical analysis,the temperature dependences of channel potential,threshold voltage and subthreshold current for 6H-and 4H-SiC MESFET s are investigated.
