沉积相研究在石油和天然气的勘探与开发中有着重要的指导意义。准确地划分与认识沉积盆地中的沉积相带(区),可以帮助确定有利的油气生储地带,从而指导在有利相带(区)选择较好的圈闭进行勘探。滇东地区(包括滇黔和滇桂交界的部分地区)的中、上泥盆统是该区的勘探目的层之一。主要是巨厚的海相碳酸盐岩地层。我们通过对滇东中、上泥盆统碳酸盐岩石学和
Sedimentary facies research has an important guiding significance in the exploration and development of oil and gas. Accurately dividing and understanding the sedimentary facies belts in the sedimentary basins can help identify favorable oil and gas reservoirs and thus guide the exploration of well-selected traps in the favorable facies belt. The middle and upper Devonian in eastern Yunnan (including part of the border between Yunnan, Guizhou and Yunnan and Guangxi) is one of the exploration targets in this area. Mainly thick marine carbonate rock formation. We passed the Upper Devonian carbonate petrology in eastern Yunnan
