Seismic Description Technique of Turbidite Fan of Dongying Formation in Jinzhou A Area,Northern Liaozhong Subdepression
摘要
Abstract
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.关键词
