    摘要:

    为了认清西部斜坡高台子油层砂体分布规律,指导油气藏开发,根据岩心、录井及测井资料分析结果,并结合测井相模式,对松辽盆地北部西斜坡江桥、阿拉新、平洋地区高Ⅲ油层组沉积微相进行研究。通过对江桥至平洋地区高Ⅲ油层组沉积微相特征及发育情况的认识,认为该区主要发育三角洲前缘、滨浅湖两种类型的亚相和滨浅湖砂坝、滨浅湖混合滩、滨浅湖泥、水下分流河道、河口坝、远砂坝、席状砂、水下分流间湾等8个沉积微相类型。江桥至平洋地区分别受到齐齐哈尔物源和西部英台物源影响,三角洲前缘砂体相对比较发育;阿拉新地区无物源供给,滨浅湖相较发育,砂体相对较薄。发育砂岩上倾尖灭油气藏和砂岩透镜体油气藏。

    Abstract:

    To recognize clearly how is distributed regular of sand body of Gaotaizi reservoir in the West slope,and guide exploitation of reservoir,the study is that according to results of analysis of lots of core samples and logging data,and combine with logging facies,to study sedimentary facies of Gao Ⅲ reservoir group in Jiangqiao area、Alaxin area and Pingyang area (from Jiangqiao area to Pingyang area) of the west slope of Songliao Basin,we have found out features and condition of growth of sedimentary facies of Gao Ⅲ reservoir group from Jiangqiao area to Pingyang area,recognizing that there are two subphases included delta front and shore-shallow lacustrine and eight sedimentary facies:shore-shallow lacustrine sand dam microfacies;shore-shallow lacustrine mixing beach microfacies;shore-shallow lacustrine mud;subaqueous distributary channel microfacies;river mouth bar microfacies;distal bar microfacies;delta front sheet sand microfacies;subaqueous interdistributary channel microfacies.F容貌Jiangqiao area to Pingyang area are controlled by qiqihaer soure and west yingtai source,sand body of delta front is relatively development;there isn’t source supplied in Alaxin area,shore-shallow lacustrine relatively developed,thickness of sand body is rather thinner.Developing sand uplift piching traps and sand lens traps.
