| 摘 要： | 在充分利用岩芯、录井、测井等相关资料的基础上,总结辽河西部凹陷欢喜岭地区沙河街组的沉积相类型,首次提出运用相对单因素综合作图法来绘制各沉积时期的沉积相平面图,综合探讨了沙河街组的沉积特征及空间沉积演化规律。结果表明:欢喜岭地区沙河街组主要发育扇三角洲相、湖底扇相、滨浅湖相和半深湖—深湖相4种沉积相类型;扇三角洲砂体为欢喜岭地区主要的储集砂体,在沙河街组沉积时期持续发育,主要发育于盆地缓坡部位;湖底扇主要发育在SQ3和SQ4沉积时期,主要分布在广阔的半深湖—深湖环境内;相对单因素综合作图法可以弥补传统的沉积相作图方法精度低的不足;沙河街组的沉积相垂向演化的旋回性明显,自下而上分为两个水进旋回,分别为SQ2～SQ5沉积时期和SQ6、SQ7沉积时期;每个水进旋回初期,盆地构造活动相对较弱,水体较浅,扇三角洲沉积广泛发育,湖底扇沉积规模较小;每个水进旋回中后期,盆地构造活动强度大,湖盆水体加深,扇三角洲规模减小,而湖底扇沉积规模明显扩大,形成非常有利的储集砂体,在研究区广泛发育,是研究区深层勘探的有利目标之一。

| Abstract: | Based on the data of core,drilling and logging,types of sedimentary facies of Shahejie Formation of Huanxiling Area in the west depression,Liaohe Basin were summarized;the relative single-factor comprehensive mapping method was firstly proposed to draw the plan of sedimentary facies in different sedimentary periods;sedimentary characteristics and evolution of Shahejie Formation were discussed.The results showed that there were 4 types of sedimentary facies,which included fan delta,sub-lacustrine fan,littora... |
