塔东南地区是塔里木盆地油气勘探新区、新领域,具有广阔的勘探前景。该区表层结构复杂,资料信噪比低,严重影响了地震资料处理和区域地质研究。结合区域地质条件,对原始地震资料进行深入剖析,认为处理过程中主要难点为静校正问题严重、干扰波发育、构造复杂等三个方面。在大量试验和研究的基础上,提炼出了一套针对性的处理方法,即综合静校正、叠前组合压噪和精细成像等配套技术联合应用,能够使塔东南地区地震资料成像质量逐步提高,取得较满意的效果。
South-East Tarim Basin is a new oil and gas exploration area, a new area, with broad prospecting. The complex surface structure of the area, low signal-to-noise ratio, seriously affected the seismic data processing and regional geological research. According to the regional geological conditions, the original seismic data are analyzed in depth. The main difficulties in the processing are that the static correction problem is serious, the interference wave is developed and the structure is complicated. On the basis of a large number of experiments and studies, a set of pertinent processing methods are extracted, that is, the combined application of integrated static correction, pre-stack combined noise and fine imaging can gradually improve the imaging quality of seismic data in the southeast of Tajikistan , To obtain more satisfactory results.
