1.服务器的安装:在Tohoku大学为这个项目安装了一台数据服务器。联合实验:联合声发射测量实验与socomine合作在Soultz HDR场址进行。项目会议:1997财年和1994财年在仙台召开了三次项目会议。多分量信号处理WG:(a)采用SPM分析对三维全息图进行原位检测,(b)采用双3C探测器进行时频相干分析,(c)将小波谱矩阵分析引入声发射反射法,(d)研究三维三轴钻头VSP, (e)将三轴声发射双波分析应用于Soultz数据集。(f)开发了声发射双元自动聚类软件。AB层析成像WG: AE层析成像方法应用于soutz数据集。稀疏网络WG:定量评价了Soultz声发射网络的性能,并研究了钻头VSP、声发射反射法和重波分析的应用。消模糊填图WG:将裂缝网和地质构造信息引入消模糊填图。发现了水库内部存在地震带。对地震/地震带进行了理论和实验研究。研究了双重态的时空分布。
英文摘要
1.Installation of a server : A data server was installed in Tohoku University for this Project.2.Joint Experiment : Joint AE measurement experiment was carried out at Soultz HDR site in cooperation with Socomine.3.Project Meetings : Three project meetings were held in Sendai in FY 97 and 98.4.Multicomponent signal processing WG : (a) In-situ detectability of the 3D hodogram was examined by the SPM analysis, (b) A time-frequency coherency analysis using the double 3C detector was investigated, (c) Wavelet spectral matrix analysis was introduced into the AE reflection method, (d) The 3D triaxial drill-bit VSP was investigated, (e) Triaxial AE doublet analysis was applied to Soultz dataset. (f) A software to automatically clusterize AE doublets was developed.5.AB Tomography WG : AE tomography method was applied to Soultz data set.6.Sparse Network WG : The performance of the AE network at Soultz was quantitatively evaluated and application of drill-bit VSP,AE reflection method and doublet analysis was investigated.7.De-blurred mapping WG : Information on fracture network and geologic structure was introduced to the de-blurred mapping.8.AE mechanism WG : Existence of aseismic zone inside the reservoir was found out. Theoretical and experimental study on seismic/aseismic zones was carried out. Spatial and temporal distribution of the doublet were examined.
