摘要
通过大庆长垣东西两侧扶杨油层天然气成藏条件的比较 ,指出二者在 3个方面存在着差异 :青山口组源岩向扶杨油层的排烃条件 ,大庆长垣以东地区优于大庆长垣以西地区 ;沙河子组—营城组源岩向扶杨油层的供气条件 ,大庆长垣以东地区优于大庆长垣以西地区 ;大庆长垣以东地区扶杨油层油溶损失气量小于大庆长垣以西地区。由此造成大庆长垣以东地区扶杨油层天然气勘探效果明显优于大庆长垣以西地区。
This paper compares the reservoir formation condition of natural gas in eastern and western Fuyang reservoirs in Daqing Placanticline and shows their difference. The area to the east of Daqing Placanticline has a better hydrocarbon exhaust condition from Qingshankou Member source to Fuyang reservoir than the western area. It has an better gas supply condition from Shahezi Member Yingcheng Member source to Fuyang Reservoir than the western area. Its oil soluble lost gas is less than that in the western area. So the eastern area has more exploration advantage than the western area.
