南海中建盆地天然气水合物富集特征与控制因素
Characteristics and Controlling Factors of Concentrated Gas Hydrate Occurrence in Zhongjian Basin, South China Sea
,
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.
High saturation gas hydrate-bearing layers is the favorable target for gas hydrate exploration and development. To identify and estimate gas hydrate-bearing layers, it uses 3D seismic data which is reprocessed by broadband wave impedance inversion, attribute analysis and the calculation of base gas hydrate stability zone to study the characteristics of the bottom simulating reflector (BSR) and gas hydrate occurrence and accumulation in the Zhongjian basin. (1) The characteristics of BSR in this area is slightly different from that found in the gas hydrate drilling area, northern South China Sea. The BSRs identified in this basin are widely distributed with continuous reflections occurred in the fine-grain sediments. The BSR amplitude is particularly strong and continuous where the fault reaches the gas hydrate stability zone. (2) The saturation of gas hydrate-bearing layers is about 30%-40% of the pore space with regional high value. The gas hydrate layer has the same polarity with the seabed reflection and is characterized by continuous and strong amplitude reflections. (3) The gas hydrate-bearing layers are occurred above different depths of the BSR which is controlled by local faults and is affected by sedimentation and tectonic movements.
