微破裂向量扫描原理是为了适应微震监测的目标特性、恶劣的地表监测环境、和对应用的一般监测要求,而逐步发展起来的.它不得不放弃记录要求较高的传统定位处理方法与可能使很多台站噪声极大的等距等角阵列,使用离散稀疏台网,处理分析完整的空间记录向量.在数学上,它计算各台记录对准各扫描点的向量间的相关性程度;在物理上,则反映了破裂释放能量的分布.选择安静处布设地震台网并在数据处理中去除和压制干扰信号以获得较小振幅的随机记录,是应用向量扫描技术的必要条件.这种条件应当数值化地由地震仪器、地震台网分布、监测环境、与去噪过程判定.一般情况下,为保证监测质量,它放弃振幅较小的纵波,而使用到达地表时携带能量较多的横波,并对扫描计算使用的台站记录附加以不同的权重;为提高性价比和使微震监测成为常规手段,在满足应用必要条件的基础上,它使用一个估计的最小扫描台站数,以及携行布设的最大台站数.利用相关性的概念,它可对速度模型引起的误差进行适度校正.微破裂向量扫描是专门针对微小破裂、三分量浅地表埋设观测、稀疏布设台阵、实时监测并4D处理解释、且考虑了微震多有剪切破裂特性的地震学监测方法;它扩展了传统定位方法的监测范围,能够在地表快速施工并“看到”微破裂,性价比高,可发展成为一种日常生产监测手段. The principle of micro-rupture vector scanning is gradually developed to meet the target characteristics of microseismic monitoring, the harsh surface monitoring environment and the general monitoring requirements of the application. It has to abandon the traditional method of location processing with high recording requirements and possible Many stations are noisy with equidistant isometric arrays that use discrete sparse networks to process and analyze complete spatial record vectors. Mathematically, it calculates the degree of correlation between vectors for each scan point for each record; in Physically, the distribution of the energy released by the rupture is reflected by the fact that it is necessary to apply vector-scanning techniques by selecting the seismographic network in a quiet place and removing and suppressing interfering signals in the data processing to obtain a random record of lesser amplitudes It should be digitally determined by the distribution of seismic instruments and seismic networks, the monitoring environment and the de-noising process.Generally, in order to ensure the quality of monitoring, it abandons longitudinal waves with smaller amplitudes and uses transverse waves that carry more energy when reaching the surface , And add different weights to the station records used in the scan calculation. In order to improve the cost performance and make microseismic monitoring a routine measure, Based on the prerequisites, it uses an estimated minimum number of scanning stations and the maximum number of stations to carry. Using the concept of correlation, it can moderately correct the error caused by the velocity model. The micro-cracking vector scan is It focuses on micro-rupture, three-component shallow buried surface observation, sparse arrangement of array, real-time monitoring and 4D processing and interpretation, and considers seismological monitoring methods with microseismic shear fracture characteristics. It extends the monitoring range of traditional positioning methods, Can be quickly constructed on the surface and “see ” micro-fracture, cost-effective, can be developed into a means of daily production monitoring.
