油田新区沉积相分析——以肇州油田州371区块泉头组四段为例
|
摘要
针对油田新区面积小、井网密度小、岩性资料缺乏、相邻区块勘探程度较高、测井资料与地震资料较为丰富等特征,以肇州油田州371区块泉四段地层为例,总结出一套与之对应的沉积相分析方法。从中认识到油田新区的沉积相分析必须以其沉积背景为基础,以紧邻研究区的、在同一环境下沉积的地层岩心资料、测井资料为依托,建立测井相标志,从而确立沉积微相类型,进行测井相分析。结合精细三维地震资料,最终预测沉积微相的平面展布规律,以指导研究区的储层预测。
Newly developed areas are featured by small area,low well spacing density,insufficient lithology information,while the adjacent regions have high prospecting degree and abundant logging information and seismic data.This paper presents a series of methods of sedimentary facies analysis by taking the 4th member of the Quantou formation of the Zhou 371 block in the Zhaozhou oilfield as an example.It is recognized that the analysis of sedimentary facies must be based on depositional setting,rely on core and logging data from the adjacent regions belonging to the same sedimentary environment.Electrofacies markers shall be set up to establish the types of sedimentary microfacies and to analyze the electrofacies.The plane distribution of sedimentary microfacies is finally predicted with combination of high-precision 3D seismic data to guide reservoir prediction in the study area.
