摘要(Abstract)：

在"相-势耦合"控藏模式的基础上,融合"源控论"思想,提出"源-相-势耦合"控藏作用定量模型,并利用该模型对东营凹陷南坡金8一滨188井剖面的成藏过程进行了研究。结果表明:根据成藏期"源-相-势耦合"指数的分布,确定了金8一滨188剖面Ⅰ类、Ⅱ类和Ⅲ类有利区;Ⅰ类有利区成藏最有利,从成藏期开始到现今都具备优越的成藏条件;Ⅱ类有利区成藏较有利,在成藏期的大多数时间都具备优越的成藏条件;Ⅲ类有利区至少在成藏期内的一段时间具备优越的成藏条件。在金8一滨188井剖面缓坡带的滩坝砂具有最高的"源-相-势耦合"指数,是Ⅰ类有利区;位于坡底的浊积岩透镜体、同沉积断层上升盘构造圈闭以及缓坡带的三角洲具有好的"相"和"势",是Ⅱ类有利区;位于坡底的深部滩坝砂在超压对油气的驱动下也可以成藏,是Ⅲ类有利区。
On the basis of the reservoir controlling mode of "facies-fluid potential integration",combined with the theory of " source rock control",the quantitative model of reservoir control by " source rock-facies-fluid potential integration" is presented;at the same time,with the help of the model,the hydrocarbon accumulation process isresearched for the cross section from Well Jin 8 to Well Bin 188 on the south slope of Dongying Sag.The results show that according to the index distribution of the above integration in the period of hydrocarbon accumulation,three hierarchies of favorable blocks are determined across the above section;the most favorable block is labeled as Hierarchy Ⅰ area,which has the super accumulation conditions from the very beginning to nowadays;the moderate favorable block is shown as Hierarchy Ⅱ area,which has advantageous accumulation conditions in the most period;the rest block having the advantageous conditions in a certain time is regarded as Hierarchy Ⅲ area.There are the highest integration index in the beach-bar sand on the gentle slope belt of the above section,so this region is considered as the most favorable(Hierarchy Ⅰ) areas;the turbidite lenses at the bottom of the slope,the uplifted-wall structural trap of the synsedimentary faults and the delta of the gentle slope belt show the moderate favorable facies and fluid potential,so they are regarded as relatively favorable areas(Hierarchy Ⅱ);the beach-bar sand at the bottom of the gentle slope can be enriched by hydrocarbon with the help of the overpressure on the hydrocarbon and finally accumulate the reservoirs—Hierarchy Ⅲ favorable block.
