| 摘 要： | 沉积微相划分及有利沉积微相带筛选是油气田地质研究的基础工作,本文针对陕北斜坡东南部下寺湾油田研究区延9储层分流河道骨架砂体识别及有利沉积微相带分布研究,提出了基于地质历史时期沉积水动力能量分析的划相方法.该方法有效的避免了薄互层砂体累加厚度对沉积微相划分的干扰,可以在平面上快速准确的评价划分沉积能量等级,并筛选有利沉积相带.特别是在平面上井数较多,地质资料繁多的情况下可以利用沉积水动力定量参数快速确定不同沉积微相带边界.总体而言,该方法理论基础充分,且具有较高的实用性和可操作性.

| Abstract: | The division of sedimentary micro-faces and favorable micro-faces analyse is the basic work for oil-gas geological research.This paper base on the favorable Sedimentary micro-faces study of Xiasiwan oil-field Yan-9 reservoir distribute channel sand-bodies.It is in the southeast of Shan-bei slope.This paper,we present a new method to guide the micro-faces divide.It is the hydrodynamic energy analysis based on the lithological logging.The method avoids the interference of sand thickness in thin-bedded alternation of strata.So,a more fast and accurate evaluation method for sedimentary micro-faces is made out.Especially in the area with large number of wells and geological data,it can give us accurate quantity factor for the micro-faces boundary estimate,and save more time.So,the rationale of this process is sufficient,and it has more higher practicality and operability to carry out. |
