CFP成像有共聚焦和双聚焦两种形式。前者用于寻找构造信息 ,后者则主要用于分析与储层描述有关的信息。借助于两个连续且相互独立的聚焦步骤 ,CFP成像技术将叠前偏移与速度分析分离开来 ,用算子更新代替传统的对速度场直接更新 ,最后由经正确更新的聚焦算子反演出地下速度场。该技术在精确成像的同时 ,很好地避免了速度难题。这一优良特性可被广泛应用于地震数据反演和处理的各个方面 (处理复杂近地表难题、多次波消除、多分量偏移、地下盐丘成像及时延地震监测等 )。因此 ,CFP成像技术是一种理论上先进、应用前景广阔的新的成像技术 ,对复杂地质问题的解决更是有着独到的功效 ,在我国可望有广阔的发展空间
CFP imaging confocal and dual-focus two forms. The former is used to find the construction information, the latter is mainly used to analyze the information related to reservoir description. With two successive and independent focus steps, CFP imaging separates the prestack migration from velocity analysis, replacing the conventional velocity field update with operator update, and finally updating the velocity field with correctly updated focus operator Performance underground speed field. The technology is precisely imaging the same time, a good speed to avoid the problem. This excellent feature can be widely used in all aspects of seismic data inversion and processing (dealing with complex near-surface problems, multiple wave elimination, multi-component migration, subsalt salt imaging and time-lapse seismic monitoring, etc.). Therefore, CFP imaging technology is a new imaging technology with advanced theory and broad application prospect. It has a unique effect on the solution of complex geological problems, and it is expected that there will be a vast space for development in our country
