| 摘 要： | 利用TOUGHREACT软件,根据示范工程实验区大情字井的地层条件,针对含油及非含油储层哪一条件更适宜CO_2地质储存,设置了盐水组与含油组两组方案进行对比模拟。结果显示,含油组地层水中主要离子浓度及总矿化度低于盐水组,主要固碳矿物片钠铝石的生成量和CO_2的封存量明显小于盐水组。残余油的存在降低了矿物与水溶液进行离子交换的比表面积和储层的含水饱和度,并且占据矿物沉淀空间。尽管水岩作用受限,但油藏仍然可完成CO_2地质封存,且诸多优点表明油藏仍是CO_2地质封存的有利场所。

| Abstract: | Based on the geological conditions of Well Daqingzi in the demonstration project area，the authors used TOUGHＲEACT to design two schemes including oil group and saline group，to explore oil reservoirs and non- oil reservoirs，which is more suitable for CO 2 geological storage． The results show that the main ion concentration and total salinity of the formation water in the oil bearing group is lower than that of the saline group，so do the amount of dawsonite which is the main mineral for CO 2 geological storage，and the CO 2 mineral trapping in the oil group． The existence of the residual oil reduced the specific surface area and water saturation for the ion exchange between the mineral and the formation water，and occupied the space of mineral deposits． Though water-rock interaction is limited，CO 2 geological storage can be completed in oil reservoir，and there are many advantages showing that oil reservoir is still beneficial for CO 2 geological storage． |
