PETROLEUM GEOLOGY OF SAUDI ARABIA AND CURRENT RESOURCE STATUS
-
摘要:
沙特阿拉伯油气资源世界排名首位，所处盆地在地史上经历了前寒武纪盐盆发育、古生代碎屑岩发育、晚二叠世—三叠纪浅海陆架发育、侏罗纪—白垩纪陆架盆地发育和新生代盆地定型共5大阶段，孕育了二叠系、侏罗系和白垩系3大套成藏组合，为巨型油气的富集创造了良好的条件。深层古生代、老油田低孔低渗储层以及非常规油气藏将是中国石油公司谋求上游合作的有利方向。
Abstract:Saudi Arabia ranks number 1 in the world in terms of oil and gas resources. In geology, it could be divided into 5 stages of evolution. It started as a salt basin in the time of Precambrian, and then filled with clastic deposits in Paleozoic, shallow marine shelf sediments in Late Permian-Triassic, shelf basin deposits in Jurassic-Cretaceous and basinal deposits in Cenozoic, which gave birth to three major sets of reservoir combinations, including the Permian, Jurassic and Cretaceous reservoirs, and thus created favorable conditions for the accumulation of large amount of oil and gas. Deep Paleozoic reservoirs with low porosity and permeability in some matured fields as well as unconventional oil and gas will be the main targets for Chinese Petroleum Companies to look for in cooperation with Saudi Aramco in the upstream fields.
