为解决常规矩形处理时窗在复杂构造区难以满足同套地层采用同一处理参数的缺陷,提出基于地质层位约束的窗口定义方法,改善复杂构造区地震成像品质.首先拾取地质层位,然后根据处理环节需要引入地质层位约束处理范围,实现地质层位约束下的处理.实际资料处理结果表明,采用层约束处理方法,提高了处理精度,较好地解决了无层位约束处理导致的同套目的层成像特征差异较大的难题.该方法对目的层一致性处理有更强的适应性,能有效提高复杂构造区地震成像品质,减少构造解释风险.%The definition of the processing time window should be based on the change characteristics of the strata.Conventional processing multi window is a rectangle,when little change in the structure can meet the processing demand,the dramatic changes in the structure,rectangular window exists obvious defects:velocity analysis process cannot reference geological horizon finely defined interface mutation rate;resection,noise suppression according to geological horizon distribution characteristics of fine processing.And with the help of geological formation of the constraints can be the establishment of relatively stable and reliable velocity model,strata bound incident angle resection,the geological horizon restriction stack pre-and post stack noise suppression,improve achievement profile of the signal to noise ratio and the processing precision.
