断砂配置输导油气时间有效性研究方法及其应用
|
摘要
为了研究盆地内下生上储式生储盖组合中油气的分布规律,针对目前断砂配置输导油气时间有效性研究这一薄弱环节,通过确定断裂输导油气时期和砂体侧向输导油气时期,确定断砂配置输导油气时期,再与烃源岩排烃高峰期对比,建立了一套断砂配置输导油气时间有效性的研究方法,并将其应用于渤海湾盆地南堡凹陷老爷庙构造东二段和东三段油藏。结果表明,老爷庙构造东二段和东三段断砂配置输导油气时期为明化镇组上段沉积期,晚于沙三段和沙一段烃源岩第一次排油气高峰期(馆陶组沉积中期),不利于该高峰期油气运移,但略晚于沙三段和沙一段烃源岩第二次排油气高峰期(明化镇组下段沉积末期),能输导烃源岩该期排出的一定量油气,较有利于油气聚集成藏,与目前东二段和东三段已发现油气分布相吻合,表明该方法用于研究断砂配置输导油气时间有效性是可行的。
In order to study the distribution of hydrocarbon which was generated in the lower source rocks and accumulated in the upperreservoirs in the source-reservoir-caprock combinations of a petroliferous basin, aiming at the time effectiveness of fault-sand configurationtransporting hydrocarbon currently, and based on the determination of fault transporting-and sand transporting-hydrocarbon time, the timeof fault-sand configuration transporting hydrocarbon is determined. Then compared with the hydrocarbon expulsion peak time, the paper establishes a method to study the time effectiveness of fault-sand transporting hydrocarbon and applies the method in Ed_2 and Ed_3 reservoirsin the Laoyemiao structure of the Nanpu sag. The study results show that the fault-sand transporting hydrocarbon time of Ed_2 and Ed_3 reservoirs in the Laoyemiao structure should be the deposition period of the upper Minghuazhen formation, later than the first hydrocarbon expulsion peak(middle deposition period of Guantao formation) of the source rocks of Es_3 and Es_1, which was not conducive to the hydrocarbonmigration in this first peak period. However, the period of fault-sand configuration transporting hydrocarbon was slightly later than the second hydrocarbon expulsion peak(late deposition period of the lower Minghuazhen formation) of the source rock of the Es_3 and Es_1 and a certain amount of hydrocarbon could be transported, which was good for hydrocarbon accumulation. The results are consistent with the distribution of the hydrocarbon discovered in Ed_2 and Ed_3, which shows that the method is feasible to be used in time effectiveness research ofthe fault-sand configuration transporting hydrocarbon.
