【摘要】 双城-太平川地区为松辽盆地北部重要的油气勘探区域,通过对该区青1段、青2+3段、嫩1段和侏罗系暗色泥岩的有机质丰度和成熟度的综合分析,结果表明成熟的青1段泥岩是该地区最主要的烃源岩,青2+3段有局部的生烃贡献,嫩1段的生烃意义有限,侏罗系只能作为煤成气烃源岩。利用热演化程度参数推断出该区源岩的生烃模式和两个生烃高峰阶段。在此基础上,通过对不同构造单元的青1段泥岩生烃潜力与成熟度的综合评价,明确了该区3个有利的青1段生烃方位。更多还原

【Abstract】 Shuangcheng-Taipingchuan is an imporment petroleum exploration area in the north of Songliao basin.The analysis of abundance of organic matter and maturity on Qing 1 Member,Qing 2+3 Member,Nen 1 Member and Jurassic shale indicates that mature Qing 1 Menmber shale is the major petroleum source rocks,Qing 2+3 Member shale also makes some contribution to the formation of hydrocarbon.However,the production of hydrocarbon of Nen 1 Member is limited,and Jurassic shale only is a coal type gas source rocks.Based on thermal maturity parameters.Hydrocarbon generation model and two hydrocarbon-producing peaks in potential source rocks in the area are proposed,and the hydrocarbon-generating potential and maturity of Qing 1 Member source rocks is evaluated.Accordingly,3 positions of favourable hydrocarbon source are determined.更多还原
