【摘要】：大庆榆树林油田扶杨油层沉积过程发育多期河道砂体,其呈狭窄条带状相互叠置且区域相变快,这些复杂的沉积特征制约着油田的开发。如何进行储层预测、提高预测精度客观合理的确定砂体分布一直是在科研生产中面临的主要问题,直接影响着油田下一部的勘探开发。本文在对树123区块沉积、构造分析的基础上,应用地震属性提取、地质统计学反演对扶杨油层进行砂体级别的储层预测。得到成果和认识如下:通过开展井震联合统层,建立等时地层格架,扶杨油层自上到下分别划分了6个油层组,即FⅠ、FⅡ、FⅢ、YⅠ、YⅡ、YⅢ组,38个小层。树123区块扶杨油层存在“东高西低,北高南低”的构造形式。同时研究区整体断层发育,目的层内部从下至上,断裂继承性发育的较好,断层系内大型断层以南北向发育为主,小型断层以东西向为主。对研究区进行沉积相分析认识到,物源主要来源于北东方向,发育河流-三角洲体系。密井网区利用测井数据,稀井区利用地震储层预测结果,对研究区平面沉积微相展布进行研究。最终在沉积相约束下,利用反演结果,对含油小层的砂体进行刻画。认为在构造及沉积背景的影响下,研究区砂体多呈南北、北东向条带状或块状展布。其分布特征为寻找油气富集有利区提供有利依据。
[Abstract]:The depositional process of Fuyang reservoir in Daqing Yushulin Oilfield is characterized by multi-stage channel sand body, which is a narrow strip superimposed on each other, and the regional phase transition is fast. These complex sedimentary characteristics restrict the development of the oil field.How to predict reservoir and determine the distribution of sand body objectively and reasonably is always the main problem in scientific research and production, which directly affects the exploration and development of the next oil field.On the basis of sedimentary and structural analysis of block Shu123, this paper uses seismic attribute extraction and geostatistical inversion to predict reservoir level of sand body in Fuyang oil reservoir.The results and understandings are as follows: through the development of the combined well and earthquake formation and the establishment of isochronous stratigraphic framework, Fuyang oil layer is divided into 6 reservoirs from top to bottom, namely F 鈪，
