查询词典 water column

Biodegradation is a dynamic process, where the diffusion of hydrocarbon to oil water contact, the diffusion of metabolites away from the reaction site to the oil column. Late charging and mixing occurred in the reservoir also control on the degree of biodegradation.

生物降解是一个动态过程，烃类不断向油水界面扩散，降解过程中新形成的代谢物从油水界面向油柱扩散，后期充注及油藏内的混合作用也是控制生物降解作用程度的重要因素。

Depending on the geometry of gas-cap and oil column, the physical property and geometric shape of reservoir, and the mobility of edge and bottom water, the multiple oil-driving mechanisms exist in gas-cap reservoirs where there are gas-cap and oil/gas interface, and the recovery factor changes a lot because the oil/gas interface moves during exploitation of gas-cap reservoirs and it is very difficult to adjust and control the oil/gas interface.

气顶油气田因气顶及油气界面的存在，同时因气顶和油环的大小、储层物性、几何形态不同和边底水活跃程度不同，致使气顶油气藏在开采过程中具有多种驱油机理，采收率变化较大，这关键是气顶油气藏在开发过程中存在油气界面的移动问题，而调整和控制油气界面是相当困难。
