Over past few years, the research in glutamate receptors and their genes suggested that glutamate receptors are diversified in structure and function due to multiple genes,alternative splicing, RNA editing and heteromeric formation.
Through the summary of sealing capacity, types of hydrocarbon spilling (orleaking) and differential entrapment model, the authors discussed the hydrocarbon migra-tion and entrapment model within faulted structure and top leaking differential entrapmentfor series of fault traps by taking Biyang depression as an example.
