摘要： 基于地质背景和大量钻测资料，利用流体包裹体和成岩矿物组合的地球化学特征，以成岩流体类型和活动历史为视角，综合分析了琼东南盆地东部宝岛凹陷北缘储层异常高孔带的动态成因过程。研究区发育了三段异常高孔带，其中前两段在全区均有发育，第三段仅在BD19-2构造部分井发育。控制该区异常高孔带发育的流体类型为有机酸、大气淡水、烃类、热流体和无机幔源CO2。在中新世早中期，大气水淋滤引起溶蚀，持续至中新世中期；中新世末期陵一段泥岩生排的有机酸进入储层，再次发生溶蚀形成次生孔，第四纪热流体的溶蚀作用最终形成第一段异常高孔带。中新世末期陵二段泥岩排出的有机酸引起溶蚀，持续到上新世中期，上新世早期天然气充注抑制了碳酸盐胶结物充填孔隙，与此同时热流体活动也引发溶蚀，综合形成第二段异常高孔带。中新世早期下伏崖城组源岩开始生排有机酸引起溶蚀，持续至中新世中期，中新世末期陵二段泥岩开始生排有机酸再次引起溶蚀，持续至上新世中期，中新世中期天然气充注抑制了碳酸盐胶结物充填孔隙，上新世富幔源CO2的热流体开始活动溶蚀，综合形成第三段异常高孔带。

Abstract: Based on geological background and abundant drilling data,by means of fluid inclusion analysis technique and the geochemical characteristics of diagenetic minerals,this paper has studied the dynamic formation process of abnormal high pore zones in the eastern Qiongdongnan Basin with perspective of pore fluid source and evolution.There are three abnormal high porosity zones.The previous two zones develop in whole region and the third one only develops in BD19-2 structure.Organic acid,atmospheric fresh water,hydrocarbon,thermal fluid and mantle-derived CO2 are recognized as the geological fluids which affect porosity zones.The leaching of meteoric water during stage of structure uplift in the Miocene and the dissolution of organic acid from source rocks has combined to cause the development of the first abnormal high porosity zone.The dissolution of organic acid in the Middle and Late Miocene,the inhibitor of development of carbonate cements for hydrocarbon filling in Late Miocene and the dissolution of thermal fluid activity in late stage have combined to cause the development of the second zone.The dissolution of organic acid in the late Oligocene,the inhibitor of development of carbonate cements for hydrocarbon filling in the Middle Miocene and the dissolution of thermal fluid which contains mantle-derived CO2 activity in late stage have combined to cause the development of the third zone.

Key words: Abnormal high porosity zone, Diagenetic fluid, Activity history, Qiongdongnan Basin
