【摘要】 火成岩对地震反射存在明显屏蔽效应,而重磁电勘探获得的异常信息则是地下地质目标的体积效应,不存在这种特点,重磁电震多种资料的互补可增强火成岩目标的认识。通过阳信地区三维重磁电资料的处理与地震、钻井资料的综合分析,认为区内多发育北西向深大断裂,具有较强的继承性,是火成岩发育与油气运移的通道。其中,沙三段火成岩发育较薄,分布范围有限;沙四上段火成岩发育范围广,厚度大,为引起本区磁异常的主要磁源体。分析认为,Y101构造属背斜正向构造带,东西两侧存在生油洼陷,且断裂非常发育,是沙四段火成岩成藏有利区带。

【Abstract】 The igneous rock has screening effect for the seismic reflection,the abnormal information acquired by GME exploration technology do not have this characteristics as it is the volumetric effect of the target of the subsurface geology,the complementation of the gravity data,magnetic data,electric data and seismic data can improve the identification of the igneous rock target.The analysis of the 3D GME data combined with the seismic data and drilling data show that the discordogenic faults are developed in NW in the area,which are of stronger inherited,and the channels of the igneous rock development and hydrocarbon migration also.In which the igneous rock of the Es 3 are thinner,and their range of the distribution is limited,meanwhile,that of the Upper of the Es4 are thick,their range of the distribution is extensive,it is the main magnetic source bodies which result in the area magnetic anomaly.The analyzed result show that the Y101 is a anticline forward direction structural belt,the oil-generating sags are on the both sides,and faults are developed very much,it is a beneficial area for the igneous rock reservoirs of Es4 .
