库车东部是库车坳陷侏罗系致密砂岩勘探潜在领域。工区地震资料采集较早,受当时勘探设备和处理技术的限制,不同年度基准面不统一,静校正问题突出,有效波能量弱,资料信噪比低,给该区的地质研究和圈闭搜索工作造成了较大困难。通过对老资料特点的深入分析,提炼了一套针对性较强的处理技术,即采用连片静校正、多域多步组合去噪、处理解释一体化精细成像等配套处理技术。最终资料品质逐步改善,充分挖掘了老资料潜在价值,取得了满意的效果,为后期区带研究、圈闭落实提供了真实、可靠的基础资料。
The eastern part of Kuche is a potential area for exploration of tight Jurassic sandstones in the Kuqa Depression. The collection of seismic data in the work area was earlier, limited by the exploration equipment and processing technology at that time, the non-uniform datum of different years, the problem of static correction, the weak effective wave energy and the low signal-to-noise ratio of the data, Work caused great difficulties. Through the deep analysis of the characteristics of the old data, a set of highly targeted processing techniques are refined, that is, the concomitant processing techniques such as contiguous static correction, multi-domain and multi-step combination denoising, and processing and interpretation integrated fine imaging are adopted. The quality of the final data gradually improved, fully tapped the potential value of the old data and achieved satisfactory results, which provided a real and reliable basic data for the research on the zoning and the implementation of the traps in the later period.
