摘要
多年来受制于方法本身的复杂性,地-井TEM法的反演解释以定性和半定量解释为主,难以更加精细地对实测曲线做出进一步的解释,等效电流环的出现使得快速定量反演得以开展,但是电流环未知参数多、约束难,自动反演很难开展。有鉴于此,采用Matlab GUI平台编制了基于等效电流环的人机交互快速成像程序,以人机交互方式对地-井TEM异常场进行快速成像,依据异常曲线特征给定电流环初始参数,结合拟合曲线,时时修正电流环各参数,最终获取了异常的中心位置和空间展布参数。
Over these years,subject to the complexity of the method itself,Borehole TEM inversion method and interpretation rely on the qualitative and semi-quantitative.It is difficult to make more elaborate further explanation to the experimental curve,the appearance of filament current makes quick quantitative inversion can be carried out.However,unknown parameters and difficult constraints make it difficult to carry out automatic inversion.In view of this,this paper uses the Matlab GUI platform to procedure fast imaging based on equivalent currents,and image borehole TEM anomaly field by the way of human-computer interaction.To give initial parameters according to characteristics of anomalies curve,combined with the fitting curve,revised current loop parameters timely,finally,obtained the center position and the spatial distribution parameters of anomalies.
