【摘要】 潮汕坳陷是一个以中生界为主体的坳陷,油气勘探程度极低,仅有1口探井且位于坳陷边缘。根据研究区地震资料丰富的实际情况,进行了中生界地震相-沉积相的研究工作,将潮汕坳陷中生界划分为3个地震层序,根据地震波组反射特征,划分出8种不同的地震相类型,在地震相的平面图和地震层序等厚图编制的基础上,编制了潮汕坳陷中生代各时期的沉积相图,恢复了潮汕坳陷中生代各时期的沉积面貌,为该区的进一步勘探工作提供了基础性依据。更多还原

【Abstract】 Chaoshan sag is mainly composed of Mesozoic strata.It was only one exploration borehole drilled on its margin;as a result the exploration level is extremely low.Due to the rich seismic data,the study on seismic facies-sedimentary facies is carried in this paper.The Mesozoic of Chaoshan sag can be divided into three seismic sequences and eight seismic facies are identified according to the reflecting characteristics of seismic wave group.Based on the mapping of seismic facies and seismic sequence isopach,the sedimentary facies distribution in different periods of Mesozoic can be recovered.This study can provide fundamental basis and advice for further exploration work as well.更多还原
