摘要二連盆地是在海西期地槽褶皺基底上發育起來的早白堊世斷陷湖泊群，具有湖盆湖浸規模較小、氣候條件乾燥、湖水咸化、沉積旋迴單一，多物源、近物源和粗碎屑等沉積特徵，以及發育巖性地層油氣藏為主的油氣分佈特點。 -
According to the abundance well logging, mud logging and core analysis data, gaotaizi reservoir has been classified into four sand group with the principle of cycle comparison and classified control. based on the detailed study of lithologic character, sedimentary structure, paleontologic fossils, depositional sequence, rock association and logging data, the microfacies of the studied area are divided into such seven types : subaqueous distributary channel microfacies ; river mouth bar microfacies ; subaqueous interdistributary channel microfacies ; subaqueous crevasse channel microfacies ; subaqueous natural barrier microfacies ; distal bar microfacies ; delta front sheet sand microfacies. the characteristic of each sedimentary microfacies are described detailedly
通過研究大量測井、錄井資料和巖芯資料，依據「旋迴對比，分級控制」的原則，把研究區高臺子油層劃分為g 、 g 、 g 、 g四個砂層組。通過對研究區巖性、沉積構造、古生物、沉積序列、巖石組合及測井曲線特徵進行研究的基礎上，認為研究區高臺子油層屬於三角洲前緣亞相沉積，並將研究區沉積微相劃分為：水下分流河道、河口壩、水下分流河道間、水下決口扇、水下天然堤、遠砂壩、席狀砂等七種微相類型。 -
The lithological traps related to jishan delta ? turbidite fan depositional system inherently developed during the base level falling period of c3 cycle and the base level rising period ; the lithological traps related to the underwater fan depositional system near xiakou fault developed during c2 cycle ; the lithological traps related to qudi fan delta developed during the base level falling period of c2 cycle ; and there are a few lithological traps related to shangfeng delta. these predicted traps are mainly distributed in the deeply low - lying areas
在沉積體系、沉積相研究的基礎上，對臨南窪陷沙三段巖性圈閉分佈作出了預測，指出了各旋迴基準面下降期是尋找巖性圈閉的有利層序地層位置， （扇）三角洲前緣滑塌作用或快速充填作用形成的濁積扇或滑塌作用形成的濁積巖體是巖性圈閉形成的主要場所。 -
