摘要: 车镇凹陷沙二段沉积时期发育了一定规模的滩坝砂体,对于其沉积迁移规律等的认识不够深入,制约了滩坝砂油藏的精细勘探开发进程。为了进一步明确研究区滩坝砂体的沉积迁移规律,在充分利用岩心、录井、测井及相关测试资料的基础上,系统研究了滩坝砂体的沉积特征及控制因素。结果表明:车镇凹陷沙二段滩坝砂体以岩屑长石砂岩为主,粒度概率曲线以反映波浪作用的跳跃加悬浮式和两段跳跃加悬浮式为主;滩坝砂体沉积构造类型多样,主要发育反映波浪作用的浪成沙纹交错层理和沙纹交错层理、反映强水动力作用的平行层理,以及反映生物作用的生物钻孔和生物扰动构造;滩坝砂体主要为原地改造型,垂向上主要发育反粒序特征明显的坝砂和相序不明显的滩砂,局部地区发育由于波浪作用改造不彻底而形成的正粒序或复合相序;断层活动控制了滩坝砂体的沉积迁移规律,波浪作用控制了原地改造型滩坝的发育,物源供给控制了滩坝砂体的发育规模;整体上,车镇凹陷沙二段滩坝砂体具有“漫湖”沉积特征,成分成熟度和结构成熟度均中等偏低。研究结果可为车镇凹陷沙二段滩坝砂油藏的进一步勘探开发提供参考。
