摘　　要：LT33-1岩性体的综合解释与评价应用了多项地震识别技术,但该岩性体最终钻探失利.在对失利原因进行深入分析的基础上,探讨了地震识别技术应用中的有关问题,认为:运用地震识别技术对非构造圈闭进行评价,要遵循一定的地质规律;基础工作要做得精细、扎实;对所用技术方法的适用条件、局限性要有透彻的理解,强调适当应用;要将各种研究成果有机地结合在一起,相互佐证.Several seismic identification techniques have been used to make an integrated interpretation and evaluation for LT33?1 lithologic body in Yinggehai basin, but a well drilled on the interpretation results has failed to get a discovery. Based on an analysis of the failure causes, some problems about the application of seismic identification techniques are discussed. This discussion has resulted in some useful conclusions: (1) a certain rule of geology has to be followed when seismic identification techniques are used to evaluate non_structural traps; (2) the basal researches have to be done carefully and firmly; (3) the applicability and limitation of the used techniques have to be understood thoroughly; and (4) various research results have to be combined intrinsically.
