| 摘 要： | 长岭断陷经历了三大演化阶段: 断陷期、坳陷期和反转期。在营城、嫩江和明水末期，断陷整体隆升，地层遭受剥蚀。依据地震、钻井和测井资料，选用声波时差法和地层趋势延伸法，对断陷中的4 口井进行了剥蚀量计算。结果显示，营城、嫩江和明水末期平均剥蚀量分别为417. 5 m、205 m 和342. 5 m。在地层剥蚀量计算的基础上，进行了构造演化史恢复和研究。结合储层流体包裹体的均一温度测试结果，得出长岭断陷各构造单元油气成藏期次，双坨子构造营城组和登娄库组天然气均具有两期成藏，哈尔金构造营城组和登娄库组具有一期成藏，伏龙泉构造泉头组天然气具有一期成藏。

| Abstract: | Changling fault depression went through three stages in evolution，including the faulted period， depression period and inversion period． The fault rised and the formation generated erosion were in the late Yingcheng formation，late Nenjiang formation and late Mingshui formation． Based on seismic and drilling data of the 4 wells located in the studied area by sonic velocity analysis and stratigraphic trend extension method，we get the result that the average erosion volume of the three periods mentioned above were 417. 5 m，205 m and 342. 5 m respectively． Based on the stratigraphic denudation quantity calculation and the comprehensive study on homogenization temperature fluid inclusion in reservoir，we research on the oil-gas reservoir forming time and the period of each tectonic unit in Changling fault depression． The Yingcheng Formation and Denglouku Formation of Shuangtuozi structure have gas accumulation for two phases． The Yingcheng Formation and Denglouku Formation of Haerjin structure have gas accumulation for one phase． The Quantou Formation of Fulongquan structure has gas accumulation for one phase． |
