【摘要】 升平地区是松辽盆地北部徐家围子断陷带北翼斜坡上的一个代表性的含气隆起。本论文以松辽盆地北部升平地区最新三维地震资料以及构造特征为研究内容。以前人的研究成果为基础，以构造地质学、层序地层学、沉积学为指导针对升平地区开展精细的地震资料构造解释。研究区地震界面T₅、T_4-2、T_4-1、T₄、T₃为重要的不整合面，地震、钻井资料不整合特征明显。在准确的鉴别、追踪区域不整合界面基础上，结合该地区地质分层，应用新方法建立研究区三维空间速度场，实现连续变速成图。通过对构造特征进行研究，对构造格局进行划分，弄清断裂带的空间展布特征。并对构造样式进行分析，该地区断陷总体呈现为西断东超的构造格局，该断陷在发育过程中，除了拉张之外，中间还发生挤压构造反转，所以研究区主要以伸展构造样式和挤压构造样式为主。其次对升平地区构造演化进行分析，通过了解它的演化历史，然后运用平衡剖面技术进行构造演化分析。对盆地地震解释剖面进行平衡复位。升平地区坳陷经历了断陷构造期、段坳转化期、坳陷构造期和反转构造期的演化过程。最后对构造特征以及研究区内构造活动对油气成藏的影响进行研究，对有利油气聚集区进行预测。更多还原

【Abstract】 Shengping area is a representative uplift gas-bearing of the Xujiawuzi fault north limb inthe north Songliao basin. This thesis is the latest3d seismic data of Shengping area in theNorth Songliao Basin for the study content. On the basis of previous research results，usingStructural geology, sequence stratigraphy, sedimentology as the guide needle，carrying out theRefined structure interpretation with seismic data of Shengping area.Study of seismic interface T₅, T_4-2, T_4-1, T₄, T3important unconformity surface,seismic, drilling data unconformity characteristics. In the accurate identification, trackingbased on regional unconformity interface, combined with the local geological stratification,the application of new method for establishing three-dimensional velocity field of study area,realize the continuous variable velocity mapping. Based on the structural characteristics of thetectonic framework,divided, understand the characteristics of the spatial distribution offracture zone. Analyze the structural styles,this area generally presents west off east supertectonic framework,the rift in the development process,except the role of the tensile.Duringthis period also occurred in compressive tectonic inversion.So the study area mainlyextensional tectonic style and compressional tectonic style mainly.Secondly,analysis of the shengping region tectonic evolution,through understanding theevolutionary history of this area,and then applying the balanced section of tectonicevolution,reset the balance of basin seismic interpretation section,Shengping area depressionperiod,depression tectonic period and inversion structure period.At last,carrying out the research on the structural feature and Influences of tectoincactivity on the formation of Hydrocarbon Reservoirs of study area that favorable block for oiland gas to accumulate is predicted.更多还原
