南海北部深水盆地新生代处于准被动大陆边缘的区域地质背景，具有北部拉张裂陷的大陆边缘性质，其凹陷裂陷深、沉积充填规模巨大，不仅有利于深水油气藏的形成，而且亦是天然气水合物形成与分布的有利区域。

Spreading cover on a stone material surface, not only is to cover the stone material hair side, hollow, crack and scratch, enhances the stone material glossiness, but also to protect the stone material from the water or other bad factors, like SO2 and so on noxious gas has corrosive nature to the stone material, thus to avoids or postpone stone material surface oxidation, so to have the protection function.

在石材表面涂覆一层遮盖品，不单纯是为了掩盖石材毛面，凹陷、裂纹和划痕，提高石材的光泽度，还可保护石材免受水或其他不良因素，如SO2等有害气体对石材的侵蚀作用，避免或延缓石材表面氧化作用的发生和发展，从而起到保护的作用。

To give some perspective to the size of the alcoves, those eroded cave-like giant dents, the lake level has dropped 25M when we were there and the width of the white-washed surface is about 25M.Now you can calculate the size of the alcoves.

On the basis of the basic principles of sequence stratigraphy,the formation of cyclical sedimentary stratum is driven by eustasy which is periodic,and by analysing the seismic,well log and nano-microfossil data of Pearl River Mouth Basin,an integrated study was conducted which is on the sequence stratigraphy of lower and middle Miocene stratum within and around Kaiping Sag .

以层序地层学基本原理——周期性海平面升降控制旋回性地层沉积——为指导，根据地震、测井和古生物资料，对珠江口盆地开平凹陷及其围区的早中新世—中中新世地层进行系统的层序地层分析，认识到该区的层序地层学特点取决于其特殊的古地理位置。

Accordingly, we start the thesis from two small oil fields of Beipu and Laoyemiao in Nanpu depression. Firstly, we analyze regional geology background of the area and find that its structure evolvement can be divided into three greatest stages: the formation and evolution of pre-tertiary basement, the lower-tertiary fault basin and the upper-tertiary depression basin.

因此本论文从南堡凹陷北堡和老爷庙两个小型油田入手，首先分析了研究区的区域地质背景，明确了其构造演化分为三大阶段：即前第三纪基底的形成与演化、早第三纪断陷盆地的形成与演化、晚第三纪坳陷盆地的形成与演化。
