南海油田烃类氧化菌生态分布初步研究

The amount of hydrocarbon bacteria in the four dominating oil-fields in the South Sea

报道了冬季南海珠江口盆地4大油田(陆丰13-1油田、流花11-1油田、CACT惠州油田和西江30-2/24-3油田)烃类氧化菌的分布和变化状况。在所有站位都检出烃类氧化菌,数量介于3.00×104～2.05×105个/L。各油田平台附近的测值高;表层的测值高于10m层。烃类氧化菌的数量与水域中的营养盐含量及其它水质因子有一定的关系。

During the winter of 2003 in the South Sea, the amount of hydro-carbon bacteria of the four dominating oil-fields, such as Oil-field of LUFENG 13-1, Oil-field of LIUHUA 11-1, Oil-field of CACT HUIZHOU and Oil-field of XIJIANG 30-2/24-3, has been studied. The number of them varied from 3.00× 10^4 to 2.05 × 10^5 cell/L. The number nearby the fiat roof is higher than that far from it and the number in the upper layer is higher than that in 10-meter layer. The number of hydrocarbon oxidation bacteria had a relationship with the supply of nutrients as well as other water factors.
