综合物探技术识别地震反射异常体属性

埋藏在6000m以下的地震反射异常体是礁体还是火成岩体？或者是海底滑塌体？在高质量重磁电资采集的基础上，通过对研究区域内的地层岩石物性细致研究，利用CEMP资料界面约束二维反演、重磁力异常剥离技术和LCT重磁力地震联合反演解释技术细致研究了异常体的物性参数，从密度、磁化率、电阻率、速度等多种特征推测判断了深层异常体地质属性，为钻井部署提供了间接依据。

Property identification of anomalous seismic bodies by GMES techniques,a case history

What are the anomalous seismic reflection bodies at depths of over 6000 m? Are they reefs or igneous rock? This is a difficult problem for seismic techniques, but the GMES technique can handle it. The GMES technique is a joint exploration technique combining gravity, magnetic, electrical, and seismic techniques. The specific procedure is to conduct a 2D interface-constrained CEMP inversion using 2D seismic and log data followed by a property parameter inversion of the anomalous bodies using gravity and seismic data by the stripping technique. We then estimate the physical properties of the anomalous bodies, such as density, susceptibility, resistivity, velocity, and etc. to deduce the geological features of the bodies and provide a basis for drilling decisions. The work in the TZ area reported in this paper shows the applicability of the technique.
