| 摘 要： | 琼东南盆地深水区经历了断陷、断拗和拗陷3大构造演化和沉积充填阶段,主要发育4种沉积体系,相应地形成了4类主要储层:1)陵三段扇三角洲或滨海相砂岩储层;2)三亚、梅山组滨浅海相砂岩储层;3)三亚—莺黄组低位体储层;4)梅山组台地边缘礁滩灰岩储层。平面上,储层发育具有明显的分带性,可划分为:北部浅水陆架滨岸砂岩、三角洲砂岩储层发育带;中央坳陷低位体储层发育带;南部永乐隆起区碳酸盐岩储层发育带。深水区主要位于后2个带,每个带储层发育的控制因素不同,可以进一步划分为多个储层发育区。每个储层发育区存在多套储盖组合,每套储盖组合在多个储层区中发育。其中台地灰岩储层可能成为南部隆起区具有重要意义的勘探层系。

| Abstract: | The Qiongdongnan Basin has undergone 3 stages of tectonic-sedimentary evolution,i.e.rift-ing,fault-depressing and depressing.There are 4 sedimentary systems which respectively develop 4 major types of reservoirs: a) the fan deltaic or littoral sandstone of Ling-III Member;b) the littoral facies sandstone of Sanya-Meishan Formations;c) the sandstone of lowstand system tract of Sanya-Yinghuang Formations;and d) the Miocene platform limestone of Meishan Formation.Spatially the reservoirs develop in 3 different zones,i.e.the northern shallow shelf zone developing deltaic and littoral facies sandstones,the central depression zone developing LST sand bodies,and the southern Yongle Uplift zone developing carbonate rocks.The deepwater area mainly covers the latter 2 zones.Due to the difference of controlling factors,each reservoir zone can be further divided into several areas,and each area may develop several reservoir-seal combinations.The Miocene platform limestone may be an important exploration reservoir in the southern Yongle Uplift. |
