为了确定松辽盆地西斜坡区萨二、三油层油气分布规律,对油气运移输导通道与油气成藏关系进行了研究。利用砂体孔隙、断裂和构造之间分布关系,对油气运移输导通道进行研究,找到了西斜坡区存在的4条主要油气运移输导通道:第1条由齐家凹陷经泰康至富拉尔基;第2条由古龙凹陷经白音诺勒至二站和阿拉新;第3条由古龙凹陷经白音诺勒至富拉尔基;第4条由古龙凹陷经巴彦查干至泰来。区内萨二、三油层组油气分布明显受油气运移通道控制:油气主要分布在4条油气运移输导通道上或附近;油气富集程度受运移输导量控制,油气输导量越大,油气富集程度越高。
In order to determine the distribution rules of oil and gas in the second and third reservoirs of the SA 2 in the western slope of the Songliao Basin, the relationship between hydrocarbon migration and transport channels and hydrocarbon accumulation was studied. Based on the distribution of sandstone pores, faults and structures, the migration and transport of oil and gas channels are studied, and four main migration channels for oil and gas migration are found in the west slope region. Fulaerji; Article 2 from Gulong Depression via Baiyinoleole to Erzhan and Allazin; Article 3 from Gulong Depression via Baiyinleole to Fulaerji; Article 4 from Baoliancha Dry to Thailand. The distribution of oil and gas in the second and third reservoirs in the area is obviously controlled by the hydrocarbon migration channel: oil and gas are mainly distributed on or near the four migration channels; hydrocarbon enrichment is controlled by the migration and transport volume, The larger the greater the degree of hydrocarbon enrichment.
