摘要
高尚堡油田位于南堡凹陷的中心,其沙三段二三亚段地层主要发育一套扇三角洲沉积体系。该油田曾被进行过多次地质研究,但研究精度尚不能满足当前精细生产的需要。本文应用成分成熟度分析、重矿物分析等物源分析方法确定高北斜坡带Es2+33亚段的物源方向主要来自北东和北西向。并通过岩心观察和描述、录井、测井及钻井等各项分析鉴定材料,明确研究区岩石的结构成熟度及成分成熟度均较低,反映扇三角洲紧邻基岩物源区,经历较短距离搬运的特点,并结合沉积构造特征以及测井曲线特征,最终确定研究区的扇三角洲沉积相主要以辫状河道(5种)、扇中前缘、沙坝以及沙席等微相较为发育,并实现对砂厚和微相平面展布特征的刻画。
Gaoshangpu oilfield,where the Fan delta facies developed during the deposits of Es3^2＋3 submember,lies in the center of Nanpu sag.Although it has been studied many times,the results required didn＇t meet the needs of lean production.In this paper,we applied compositional maturity analysis,heavy mineral study and other provenance analysis methods to determine the provenance of Es3^2＋3 submember in Gaoshangpu Oilfield.Provenance research of Es3^2＋3 summember in Gaoshangpu Oilfield indicates that the provenance mainly came from the direction of northeast and northwest.We also found that the structure maturity and composition maturity of rocks in Es3^2＋3 submember are low by using core data,log data and drilling data which reflects that the Fan delta was close to provenance and the deposits suffered a short distance transportation.Finally,in this paper,it suggests that braided channel,the front of fan,bar,inter-channel and sand sheet micro-facies developed in the research area during the sedimentary period of Es3^2＋3 submemeber,at the same time,we achieved the description of the distributional characteristics of sand bodies＇ thickness and micro facies.
