| Abstract: | The hydrocarbon accumulation period of Taizhou Formation in Haian Sag is determined according to the characteristics and homogenization temperature of fluid inclusion,and combining the forming time of traps and the history of hydrocarbon generation and expulsion.The analysis of the samples shows that there is two-period fluid inclusion.In Ⅰperiod inclusion,there is only salt-water inclusion but no organic inclusion,and its homogenization temperature is 65~75 ℃.In Ⅱperiod inclusion,there are hydrocarbon inclusion and salt-water inclusion,and salt-water inclusion is more developed.The hydrocarbon inclusion presents light yellow and tan,and it presents light yellow and yellow under fluorescence.The homogenization temperature of Ⅱperiod inclusion is 75~115 ℃ and the main peak of the homogenization temperature is 80~110 ℃.The hydrocarbon accumulation period of Taizhou Formation in Haian Sag is 19.8 Ma to now,when the fault traps were formed and the hydrocarbon generation was into peak period. |
| Keywords: | Haian Sag Taizhou Formation fluid inclusion homogenization temperature period of hydorcarbon accumulation |
