摘要
南方碳酸盐岩地层分布广、层系多、厚度大,目前除四川盆地外油气勘探尚无大的突破,但从长远看,必是下一世纪油气勘探的后备基地。建议:建立一批基干剖面;重视低渗透致密储层的研究;开展盖层和保存条件的研究;加强古岩溶与深部岩溶的研究;对南方碳酸盐岩主要沉积区(或层系)进行成岩相研究和编图;选择有利区块的有利层系打数口井;组织国内碳酸盐岩研究有专长的单位和科研人员联合开展研究工作。
The carbonate formation is wide spread in South China, there being many systems of beds and great thicness. There still hasn't been a great breakthrough of its petroleum exploration except in Sichuan Basin. But from a long-term point of view, it must be the reserve base of the exploration for the coming 21st century. Suggestions: (1) Set up some backbone sections; (2) Pay attention to the study of low perme- able and compact reservoir beds; (3) Carry on the research of cap rocks and maintenance condition; (4) Strengthen the research of ancient karst and deep karst; (5) Study the lapidofacies and make the drawing of the main carbonate deposition region (or series) in South China; (6) Select advantageous zones and series, drill some wells; (7) Organize domestic scientific research units and expert personnel and to go on to study of carbonate research.
