【摘要】：根据麻阳盆地的地质背景和密度分布特征,分析了该地区布格重力异常特征;结合以往地震资料的研究成果,从重力层面着重研究了麻阳重力高异常形成的机制,即结晶基底隆起与莫霍面抬升,并对麻阳重力高异常进行了半定量反演推断解释。根据有关文献资料,概要总结了麻阳盆地构造演化的特征,初步探讨了麻阳盆地及其深部构造的控矿意义,提出了麻阳盆地寻找油气藏的新思路。
[Abstract]:According to the geological background and density distribution characteristics of Mayang basin, the characteristics of Bouguer gravity anomaly in this area are analyzed, and the mechanism of the formation of high gravity anomaly in Mayang area from the gravity level is studied in combination with the research results of previous seismic data. That is, the crystalline basement uplift and Moho uplift, and semi-quantitative inversion interpretation of mayang gravity anomaly. Based on the relevant literature, this paper summarizes the characteristics of structural evolution in Mayang Basin, preliminarily discusses the ore-controlling significance of Mayang basin and its deep structure, and puts forward a new idea for finding oil and gas reservoirs in Mayang basin.
