【摘要】 在地表地形、地震地质条件和地质结构复杂地区 ,使用单一的地震方法寻找、落实中生界局部构造难度较大。但是 ,如果以中生界为目的层 ,对该区高精度重力资料进行二次开发 ,使用拟神经网络三维反演法和统计评估反演法做面上和局部的重新处理 ,结合地质、钻井、地震资料进行综合地质—地球物理解释 ,可普查、落实、评价局部构造 ,弥补使用单一地震方法的不足。本文以实例阐述高精度重力资料二次开发重新处理解释技术和方法以及成果。更多还原

【Abstract】 It is difficult to look for and delineate Mesozoic local structures in areas with comphcated surface terrain,seismcgeologic condition, and geologic structures. If we take the Mesozoic strata as an object to develop the high precision gravity data secondarily, the local structures can be explored, delineate, and judged, by using quasi neural network 3D inversion and statistical judgement inversion to reprocess the gravity data and doing comprehensive geological and geophysical interpretation by combining with geologic, drilling, and seismic data. This can remedy the disadvantage of using single seismic method. This paper expounds via real examples the methodology and results of processing and interpretation of old high precision gravity data in secondary development.更多还原
