通过对松辽盆地王府断陷登娄库组地层沉积特征进行研究,对岩性以及岩石粒度的变化的分析从而对登娄库组地层的旋回进行划分,借助旋回变化以及岩石岩性的变化对其地层层序进行精细划分,在组的基础上划分出段与小层。根据地震剖面、岩心、测井资料以及前人研究成果的综合分析将登娄库组地层分为d1、d2、d3三个三级层序;有根据岩石粒度变化、旋回性等特征划分分出了d12、d11、d22、d21、d32、d31六个四级层序。
通過對鬆遼盆地王府斷陷登婁庫組地層沉積特徵進行研究,對巖性以及巖石粒度的變化的分析從而對登婁庫組地層的鏇迴進行劃分,藉助鏇迴變化以及巖石巖性的變化對其地層層序進行精細劃分,在組的基礎上劃分齣段與小層。根據地震剖麵、巖心、測井資料以及前人研究成果的綜閤分析將登婁庫組地層分為d1、d2、d3三箇三級層序;有根據巖石粒度變化、鏇迴性等特徵劃分分齣瞭d12、d11、d22、d21、d32、d31六箇四級層序。

Sedimentary characteristics of Denglouku formation in Wangfu area of Songliao basin were studied, the changing of lithology and grain size composition of rock was analyzed, the cycle of Denglouku formation was divided, and then fine stratigraphical division was carried out based on the changing of the cycle and the lithology,segments and subzones were finally divided. Based on seismic section, core and logging data and predecessors' studying results, Denglouku group formation can be divided into d1, d2 and d3 three sequence; According to rock granularity, cyclicity, and other characteristics, d12, d11, d22, d21, d32, d31 six quaternary sequences were obtained.
