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。
The Chaoshan Depression is a depression mainly dominated by the Mesozoic. Its oil and gas exploration is extremely low. There is only 1 exploration well located at the edge of the depression. According to the abundance of seismic data in the study area, the study of Mesozoic seismic facies-sedimentary facies has been carried out. The Mesozoic boundary of Chaoshan depression is divided into three seismic sequences. According to the reflection characteristics of seismic wave group, eight different Based on the seismic facies plan and seismic thickness map, the sedimentary facies maps of the Mesozoic and Tertiary periods in the Chaoshan Depression were compiled and the sedimentary facies of the Chaoshan Depression in each stage were restored. Provide a basis for further exploration work.
