【摘要】 提出了地质地震综合地层划分对比法 ,介绍了该方法的实施步骤。运用该方法 ,依据井的地震合成记录分别对梨树、德惠凹陷各井的地质层位和地震层位进行了标定 ,并建立了两者之间的对应关系 ,进而进行地层划分。从区域构造演化历史出发 ,将由于构造运动的阶段性而保留在两凹陷地层中的各种地质记录 ,如沉积旋回、不整合面、岩性、岩相特征以及这些特征在地震剖面上的反映 (地震反射特征 ) ,作为进行两凹陷地层对比的标志 ,得出了梨树、德惠凹陷的地层划分对比结果 :两凹陷之间的地质层位、地震层位之间有较好的规律性和可比性 ,反映两者同处于同一区域大地构造演化背景中更多还原

【Abstract】 A geological seismic comprehensive stratigraphic division method is proposed The geologic and seismic horizons in Lishu and Dehui depressions are calibrated by well synthetic seismogram,the corresponding relation is established and stratigraphic division is conducted According to the tectonic evolutional history, all kinds of geologic records in the two depressions, such as sedimentary cycles,unconformity interfaces,lithologic and petrographical facies features as well as its seismographic reflections in the seismic reflection sections, are used as signs for stratigraphic correlation The stratigraphic correlation results show that the geologic horizons and seismic horizons between Lishu and Dehui depressions are well correlated and differences of geologic features between them are very small更多还原
