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。
In surface topography, seismic geological conditions and complicated geological structures, the use of a single seismic method to find, implement the local structure of the Mesozoic more difficult. However, if the Mesozoic is the target layer, the high-precision gravity data in the area will be redeveloped using the three-dimensional inversion method of quasi-neural network and the statistical evaluation of the inversion method for surface and local reprocessing. Combined with geology and drilling , Seismic data to conduct a comprehensive geology - geophysical interpretation, census, implementation, evaluation of local structure, to make up for the lack of use of a single seismic method. In this paper, an example is given to illustrate the secondary development of high-precision gravity data reprocessing and interpretation techniques and methods as well as the results.
