| Abstract: |
| Many oil and gas fields or traps developed in the frontal area of Longmen Mountains thrust belt by hydrocarbon exploration ,and they mainly locate in Anxian transfer zones and Guanxian transfer zones. By analyzing the sedimentary and tectonic characters of the transfer zones，the control effects of the transfer zones on hydrocarbon accumulation were studied.The results show that the two special areas have favorable terrestrial clastic reservoirs and some preferred structural traps, such as pop-up traps in shallow-middle depth and some duplex traps in deep. The transfer zones have profitable hydrocarbon exploration. |
