断裂密集带在上生下储油运聚成藏中的控制作用——以松辽盆地三肇凹陷葡萄花油层为例
|
摘要
为了研究断裂密集带在三肇凹陷葡萄花油层油成藏与分布中的作用,利用地震解释结果对断裂密集带发育及构成进行了研究。得到三肇凹陷葡萄花油层发育大量T11断裂。它们主要由断陷期形成坳陷期活动、断陷期形成坳陷期和反转期活动、坳陷期形成和坳陷期形成反转期活动的4类断裂构成。平面上呈29个密集带分布,主要分布在三肇凹陷北部和中部,为北北西、近南北和北北东向展布。由断裂密集带与葡萄花油层油藏之间关系研究得到,断裂密集带与油运聚成藏关系密切。对成藏与分布具有3个方面的控制作用:①断裂密集带边界断裂对油运移的输导,使油大面积分布在断裂密集带及其附近;②断裂密集带交叉处油更富集;③断裂密集带内的交叉构造有利油聚集成藏。
In order to study the controlling of fault condensed belts in accumulation and distribution of oil in Putaohua oil layer in Sanzhao depression,development and constitution of fault condensed belts is researched by use of seismic interpretation.It is considered that there are a large number of T11 faults in Putaohua oil layer of Sanzhao depression.The faults can be divided into 4 types: faults forming in faulted period and faulting in depression period,faults forming in faulted period and faulting in depression period and inversion period,faults forming in depression period and fault forming in depression period and faulting in inversion period.There are 29 fault condensed belts in the plane.They distributed mainly in the north and centre of Sanzhao depression and in NNW,near SN and NNE direction.By studying the relation between fault condensed belts and Putaohua oil layer,it is concluded that fault condensed belts is closely related to oil migration and accumulation and its controlling effects in oil accumulation and distribution are in 3 aspects: ① The boundary faults of fault condensed belts are oil migration pathways,and oil distributed near the fault condensed belts in a large area;② Oil more enriched in intersection of fault condensed belts;③ Cross fault structure in fault condensed belts is favorable for oil accumulation.
