随时间推移（ＴＬ）地震勘探已经在油田开发领域见到了一些成功的实例，关于ＴＬ地震勘探的可行性论证也有不少文章讨论过。但是对于陆上薄互层（储层厚度小于１０ｍ）、大地吸收较强、信噪比较低和严重空变激发、接收因素影响条件下的ＴＬ地震可行性论证和数据处理还存在一些问题需要解决。本文从实际地震数据问题（如 ５０Ｈz工业干扰、地层吸收，激发能量和频率空变、近地表鸣震干扰和接收器影响等问题）分析入手，发现这些问题难以用常规处理和互均衡处理方法来解决。为此，本文针对以上问题提出了特殊的处理方法和流程，较好地消除了这些干扰影响，并在不采用工均衡处理条件下获得ＴＬ地震储层的差异信息。
Seismic surveys over time (TL) have seen some successful examples in the field of oilfield development, and there are many articles on the feasibility of TL seismic surveys. However, there are still some problems in the feasibility of TL seismic feasibility analysis and data processing under the influence of receiving factors for the thin interbedded layers (reservoir thickness less than 10m), strong earth absorption, low signal-to-noise ratio and severe air- solve. This paper starts with the analysis of actual seismic data (such as industrial interference at 50Hz, strata absorption, excitation energy and frequency free-space, near surface strike-to-noise and receiver influence). It is found that these problems are difficult to be solved by conventional processing and equalization solve. Therefore, this paper puts forward a special method and process for the above problems, which can eliminate the influence of these interferences well and obtain the difference information of TL seismic reservoir without the use of the work-level equalization processing.
