摘要(Abstract)：

为了研究松辽盆地北部他拉海地区萨、葡油层油气富集规律，在萨、葡油层油气成藏模式及输导油气通道构成研究的基础上，通过分析断裂和砂体输导油气能力主控因素及其分布特征，结合油气富集特征，对断砂输导油气能力影响因素与油气富集关系进行研究。结果表明：他拉海地区油源断裂输导油气能力的主控因素是成藏期古断距和下伏青一段源岩排烃强度，下伏青一段源岩排烃强度与葡萄花油层油气富集之间关系密切，是造成其油气主要分布在东部的主要原因；油源断裂古断距与萨尔图油层油气富集关系密切，是造成其油气主要分布在西部的主要原因；砂体输导油气能力主控影响因素是古构造脊和优势相砂体发育及分布，古构造脊发育及分布与萨、葡油层油气富集关系密切，其发育及分布是造成油气主要富集在其东部和中北部的主要原因。研究成果为以断砂输导体系为主的勘探地区油气成藏分析提供理论参考。
In order to study oil and gas enrichment law in Saertu-Putaohua reservoirs of Talahai area in northern Songliao Basin, based on study of hydrocarbon accumulation pattern and hydrocarbon transport path composition in Saertu-Putaohua reservoirs, through analysis on main controlling factors of hydrocarbon transport capacity of faults and sandbodies and their distribution characteristics, influencing factors of hydrocarbon transport capacity of faults and sandbodies and relationship with oil and gas enrichment are studied combined with oil and gas enrichment characteristics. The results show that main controlling factors of hydrocarbon transport capacity of oil-source faults in Talahai area are paleo-fault throw during accumulation period and hydrocarbon expulsion intensity of source rocks in underlying Qing1 Member. Hydrocarbon expulsion intensity of source rocks in underlying Qing1 Member is closely related to oil and gas enrichment in Putaohua reservoir, which is the main reason for its oil and gas distribution mainly in the east. Paleo-fault throw of oil-source fault is closely related to oil and gas enrichment in Saertu reservoir,which is the main reason for its oil and gas distribution mainly in the west. Main controlling factor of hydrocarbon transport capacity of sandbodies is development and distribution of paleostructural ridges and dominant-facies sandbodies. Development and distribution of paleostructural ridges are closely related to oil and gas enrichment in Saertu-Putaohua reservoirs, which are main reasons for oil and gas enrichment mainly in their eastern and north-central areas. The research provides theoretical reference for analysis of oil and gas accumulation in exploration areas dominated by faults and sandbodies transport system.
