| 摘 要： | 基于C30重排藿烷（C30DH）和C30藿烷（C30H）热稳定性差异，研究了C30DH/C30H作为油气运移方向和充注途径的可行性.结果发现:C30DH结构稳定性高于C30H，C30DH/C30H参数具有成熟度属性；同时对比分析C30DH/C30H参数与咔唑类参数的相关性，认为两者之间正相关性明显，表明C30DH/C30H参数不仅是良好的热成熟度参数还是良好的石油充注运移参数.M油田位于Fula凹陷东部，M油田原油为弱氧化-还原、淡水-微咸水环境下低等藻类与高等植物混源生成，属于同一族群原油.利用C30DH/C30H参数示踪Fula凹陷M油田石油充注方向，油气运移途径主要为自北向南，同时还发育自西向东的运移途径；咔唑类参数也验证了C30DH/C30H参数示踪油气运移的准确性.结果表明C30DH/C30H参数是示踪石油充注途径的有效参数.

| Abstract: | Based on the differences in thermal stability of C30 diahopane(C30DH) and C30 hopane(C30H), this paper studied the feasibility of C30DH/C30H in tracing oil migration orientation and filling pathways.The result shows that the thermal stability of C30DH is considered to be higher than C30H, C30DH/C30H parameters have maturity properties. Meanwhile, contrast C30DH/C30H parameters with carbazoles, found that the C30DH/C30H parameters and carbazoles have great positive correlation. Indicate that the C30DH/C30H parameters not only is a good thermal maturity parameters but also a good in hydrocarbon charging migration. M oilfield is located in the eastern Fula depression. The oils are all normal and the source materials are dual contributions of lower hydrobiont and terrigenous higher plants, the environment is fresh to slight saline water oxidizing to reducing sedimentation, belong to the same group of crude oil.Using C30DH/C30H parameter tracer M oilfield reservoir group of hydrocarbon charging migration direction in Fula depression.The migration path of oil and gas is mainly from north to south, and it also develops from west to east. The classic carbazoles parameter also verified the C30DH/C30H tracer the accuracy of the oil and gas migration. Preliminary results show that C30DH/C30H arameters is an effective parameter for tracer oil filling way. |
