| 摘 要： | 奥连特盆地主要生烃灶位于盆地西南部,但目前已发现油藏主要分布在盆地北部地区,油气成藏特征独特。以盆地油气运移及成藏特征为基础,分析了T区已发现油田的油藏地质特征及油气分布规律,认为油源断层控制着有利成藏区的分布,构造和沉积体系联合控制着油气成藏的有利位置,断层、构造及沉积体系展布为T区油气成藏的主控因素,并以此为基础进一步指出了该地区下步勘探方向。

Main controlling factors analysis of hydrocarbon accumulation in T area of Oriente basin,Ecuador |

| Abstract: | Main source kitchen of Oriente basin is located in the southwest.At present,the discovered reservoirs are mainly distributed in the northern basin,with unique hydrocarbon accumulation characteristics.Based on hydrocarbon migration and reservoir characteristics,reservoir geological characteristics and distribution regularities of oil and gas in T area have been analyzed.The results believe that favorable hydrocarbon accumulation zone was controlled by oil source fault,favorable location of hydrocarbon accumulation was jointly controlled by structure and sedimentary system.Faults,structure and sedimentary system are main controlling factors of hydrocarbon accumulation in the T area,and on the basis of the factors,further prospecting direction in the region has been pointed out. |
