摘要
针对渤海油田辽中北洼锦州A区东二下段不同类型浊积扇内部反射结构及其地震响应特征认识难度大的问题,开展了浊积扇地震描述研究。从浊积扇形成机理出发,根据围区钻遇浊积扇体不同部位探井的相应井段的岩性及组合结构等典型特征,对不同浊积扇沉积亚相的沉积特征、岩性结构、测井和地震响应特征进行了系统的分析和描述。在此基础上,建立不同类型浊积扇模型进行地震正演模拟,并对其地震响应特征进行了深入研究,最后利用地震多属性预测技术对浊积扇的内幕进行了精细地刻画。预测了辽中北洼锦州A区东营组浊积扇有利储层发育部位,研究结果对该区浊积扇岩性油气藏勘探具有指导意义。
It is very difficult to identify internal reflection structure and seismic response characteristics of different turbidite fan in Dongying formation of Jinzhou A area,northern Liaozhong subdepression of Bohai Oilfield.To solve this problem,we describe turbidite fan by seismic data in this study.Firstly,we study the formation mechanism of the turbidite fan.Secondly,we analyze the sedimentary characteristics,lithologic structure,well logging and seismic response characteristics of different sub-facies,based on the typical characteristics of lithology and composite structure of the wells in this area.Thirdly,we build different types of turbidite fan models for seismic forward modeling,and study the characteristics of the turbidite seismic response.Finally,we get the plane distribution features of turbidite fan based on different seismic attributes.The research results predict the favorable reservoir area of the turbidite fan in Dongying formation of Jinzhou A area,northern Liaozhong subdepression,thus it has a great significance in guiding the exploration in this area.
