摘 要：
运用烷基二苯并噻吩系列参数4/1-MDBT、4,6-/(1,4+1,6+1,8)-DMDBT对高邮凹陷赤岸油田油气运移路径进行了研究:4/1-MDBT、4,6-/(1,4+1,6+1,8)-DMDBT值总体呈自东北向西南减小的趋势,反映油气自韦11井断块沿NE走向断层向其他断块运移;4/1-MDBT值在单个断块内部由东向西降低,指明断块内部油气东西向的运移路径。研究结果表明,烷基二苯并噻吩类参数亦是良好的运移参数,对同源的断块型油气藏同样适用。

摘 要：
The alkyl dibenzothiophene parameters 4/1-MDBT and 4,6-/(1,4+1,6+1,8)-DMDBT are used to trace the hydrocarbon migration direction of Chi'an Oilfield.The results indicate that these two parameters decrease regularly from the northeast to southwest,which represents the crude oil migrated from Fault Block Wei 11to other blocks with the NE strike faults'connectivity.Meanwhile,4/1-MDBT ratio reduces regularly in single fault block,which suggests the oil migration direction in single fault block from east to west.In summary,alkyl dibenzothiophenes are good trace parameters which are applicable for the same origin fault block reservoirs.
