双峰盆地晚中新世深水沉积体系发育特征与勘探前景
Characteristics of Late Miocene Deepwater Sedimentary and the Exploration Prospect in the Shuangfeng Basin
摘要
Abstract
Shuangfeng Basin is the sediment unloading area of the central canyon of Qiongdongnan Basin,with a huge scale of deep-water sedimentary system.With the acceleration of exploration in the deep water area of the northern South China Sea,the oil and gas exploration prospects in the Shuangfeng Basin are increasingly receiving attention.A systematic study was conducted on the development characteristics and oil and gas geological conditions of the late Miocene deep-water sedimentary bodies in the Shuangfeng Basin through comprehensive analysis of sea level rise and fall,seismic data reflection characteristics,etc.The research results indicate that the deep-water sedimentary bodies in the Shuangfeng Basin were mainly developed in the Late Miocene,with branch channels,channel complexes,channel-levee complexes,lobe etc.The distribution area of deep-water sedimentary bodies reach ten thousands of square kilometers,making it a potential area for ultra large scale reservoirs.Meanwhile,the western and northern depressions of the Shuangfeng Basin have good conditions of source,reservoir,and cap rocks.Due to the Shuangfeng Basin located in the deep-water to ultra deep-water zone,the quality of source rocks,the scale of hydrocarbon generation and expulsion,and the economic viability of exploration targets are uncertain factors in oil and gas exploration in this area.The result has important guiding significance for the analysis of oil and gas exploration prospects,strategic selection of areas and zones in the Shuangfeng Basin.关键词
