【摘要】：为了搞清松辽盆地构造形成与油气藏形成的关系,利用差异压实构造和反转构造理论,从构造隆起的基底凸起、构造挤压和差异压实3个主要影响因素出发,对松辽盆地6个构造的影响因素及每种因素的影响程度进行分析,研究构造与油气成藏的关系。研究结果表明:松辽盆地大部分正向构造基本都是砂岩发育区,差异压实作用形成雏形后,再经构造反转使构造的隆起幅度加大定型,反转构造具有东强西弱的特点;构造隆起幅度越大,越有利油气藏形成,构造运动趋缓时就是油气藏定型时期;朝阳沟—长春岭背斜地区油源来自三肇凹陷;古龙西地区塔66井区油气高产与同生断层有关。
[Abstract]:In order to find out the relationship between structural formation and reservoir formation in Songliao Basin, the differential compaction structure and reverse structure theory are used to analyze the three main influencing factors: basement bulge, tectonic compression and differential compaction in structural uplift. The influence factors of 6 structures in Songliao Basin and the influence degree of each factor are analyzed, and the relationship between structure and hydrocarbon accumulation is studied. The results show that most of the forward structures in Songliao Basin are basically sandstone developing areas. After the differential compaction formed its embryonic form, the tectonic inversion made the uplift of the structure enlarged and shaped, and the inversion structure had the characteristics of the east, strong and weak, the bigger the amplitude of the tectonic uplift, the more favorable the oil and gas reservoir formation, the greater the tectonic uplift, the more favorable the oil and gas reservoirs are. The oil source of Chaoyang Gou-Changchun anticline area comes from Sanzhao Sag, and the oil and gas production of Ta-66 well area in Gulongxi area is related to syngenic faults.
