建立了一套针对古生界逆冲推覆构造复杂变形区的综合物探解释方法流程,并在苏北LTQ地区获得成功应用。建立了逆冲推覆构造带的印支期前缘复杂区和后缘稳定区的构造样式格架;在推覆带构造地层分布模式指导下,通过井震结合标定了印支面、前志留面和前震旦基底的地震反射层;并通过重、磁、电、震联合验证了地质解释的可靠性。
建立瞭一套針對古生界逆遲推覆構造複雜變形區的綜閤物探解釋方法流程,併在囌北LTQ地區穫得成功應用。建立瞭逆遲推覆構造帶的印支期前緣複雜區和後緣穩定區的構造樣式格架;在推覆帶構造地層分佈模式指導下,通過井震結閤標定瞭印支麵、前誌留麵和前震旦基底的地震反射層;併通過重、磁、電、震聯閤驗證瞭地質解釋的可靠性。

A procedure of integrate interpretation method in Paleozoic thrusting nappe structure was formed and successfully applied in LTQ seismic survey of Subei area.A structural pattern including deformation region of front edge and stable region of trailing edge,which took place in Indosinian epoch,was established in the Paleozoic trust belt.Under the guidance of structural and stratigraphic distribution pattern in thrusting nappe structure,the seismic reflection of Indosinian plane,pre-Silurian plane and pre-Sinian plane were identified through wells and seismic survey.The certainty of geological interpretation was verified through the combination of gravity,magnetic,electric and seismic survey.
