对LT33-1岩性体综合解释结果的分析与思考
|
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.
