An analysis of 3D seismic data from the Zhongjiannan Basin in western margin South China Sea (SCS) reveals evidence gas hydrates and associated gases, including pockmarks, a bottom simulating reflector (BSR), enhanced reflection (ER), reverse polarity (RPR), dim amplitude zone (DAZ). The BSR mainly surrounds Zhongjian Island, covering an area 350 km2 this survey area. pockmark do not match each other; where there is developed, no BSR. hydrate layer builds upward base stability with thickness...
An analysis of the stable isotopes and major ions in surface water groundwater Leizhou Peninsula was performed to identify sources recharge mechanisms groundwater. In this study, 70 samples were collected from rivers, a lake, pumping wells. The considered have lower salinity than region study. regression equations for δ D 18 O are similar those precipitation, indicating meteoric origins. levels ranged −60<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Two isolated Neogene carbonate platforms (Xisha and Guangle platforms) have developed in the rifted uplifts since Early Miocene. A large-scale submarine canyon system, Zhongjian Canyon (ZJC), has tectonic depression between two Middle High-resolution bathymetry data 2D 3D seismic reveal existence of ZJC on present seafloor, as well intervals. It exhibits typical characteristics deepwater canyons that cut surrounding rocks indicate strong erosional features. The resulted from...
The Sunda arc convergent plate subduction tectonic system in Southeast Asia is one of the most active boundary zones world. Early studies suggest that mainly characterized by subducted accretionary margin and typical prism forearc uplift landform. latest research found Roo Rise, eastern section Christmas Island Seamount Province Wharton Basin Indian Ocean, has reached Java Trench region with movement. Compared &#8220;normal&#8221; oceanic crust process other regions arc, Rise...
Channel–levee systems (CLSs) and mass transport complexes (MTCs) are prevalent in deep-water basins, yet their interplay remains enigmatic. This study uses high-resolution 3D seismic data to investigate the architecture of CLSs MTCs, aiming explore how influence distribution MTCs Rakhine Basin, Bay Bengal. Two models built illustrate interaction between MTCs. In first model, large-scale aggradational created unfilled relief overbank environments, which acted as spatially confined topography...
The amplitude and coherence attributes of three-dimensional (3D) seismic data are used to confirm gas hydrate occurrence delineate its distribution in the Zhongjiannan basin, South China Sea. High anomalies (HAAs) distributed above or below regional base stability zone (BGHSZ), which intersect with bottom simulating reflectors (BSRs) interrupted by different types pockmarks. maximum attribute extracted along T1 (5.5 Ma) horizon is controlled widely faults. layer-bound polygonal faults (PFs)...
摘要: 寻找与识别高饱和度天然气水合物富集层是当前海域天然气水合物商业性开采的重点.通过对南海中建盆地局部三维地震资料开展宽频重处理和波阻抗反演,结合全区三维地震的精细解释、属性分析和稳定带计算,剖析中建盆地BSR(bottom simulating reflector)反射特征和天然气水合物富集程度.研究发现:(1)研究区BSR特征与南海北部钻探区略微不同,主要分布在半深海细粒沉积物,分布广且连续,当断层到达水合物稳定带处时,BSR振幅强且连续;(2)天然气水合物层饱和度约30%~40%,局部较高,富集程度为中等饱和度;(3)受沉积与构造活动影响,水合物富集层位于BSR上部不同地层深度,断层控制着水合物分布. 关键词: 天然气水合物 / 富集 宽频处理 中建盆地 构造 沉积学
Pockmarks, as depression morphology related to fluid escape on the seafloor, are revealed by 3D seismic data northwestern South China Sea (SCS) margin. The pockmarks can be classified into two groups based their various shapes in plan view: circular group and elongating group. These study area could defined mega-pockmarks because maximum diameters reach 7.5 km. They commonly develop more than one crater, which called central crater secondary crater. illuminated complicated internal...
