| 摘 要： | 已有研究表明,松辽盆地西斜坡姚家组沉积初期古湖盆大面积暴露地表,形成的姚一段区域性假整合面成为后期油气向西运移的通道,因此,研究姚家组上部地层沉积特征及其控制因素对油气的勘探开发意义重大。通过重矿物分布和小层砂岩百分含量分析,揭示了松辽盆地西斜坡地区姚家组SⅡ+Ⅲ砂组沉积时期受齐齐哈尔和英台双向物源控制。根据古构造层、古地貌形态、水体能量的控制因素分析,结合研究区49口岩心井资料和202口钻测井资料,阐明了西斜坡地区姚家组SⅡ+Ⅲ砂组主要发育水下分流河道、水下分流间湾、远砂坝、河口坝、砂坪、泥坪和混合坪7种微相类型,并总结出SⅡ+Ⅲ4、SⅡ+Ⅲ3、SⅡ+Ⅲ2、SⅡ+Ⅲ14个小层沉积微相平面展布特征及变化规律。研究区姚家组SⅡ+Ⅲ砂组在南北向物源控制下发育的7种微相中,水下分流河道和河口坝为最有利的砂体储集类型;湖水冲刷环境下形成的砂坪和混合坪很可能成为后期湖区勘探的潜在目标。

| Abstract: | Study shows that the surface area of the ancient lake of the west slope at northern Songliao basin is largely exposed during the initial deposit period of Yaojia Formation,and a regional unconformity surface as the channel of westward migration for oil and gas is formed later.Therefore,it is significant to study the deposition system of upper part of Yaojia Formation and its controlling factors on the oil and gas exploration and development.According to the analysis on the distribution of heavy minerals and... |
