罗家寨气田CO2地质封存数值模拟研究
摘要：摘要基于罗家寨嘉陵江组建立三维地质模型,利用FLAC3D-TOUGHREACT模拟评估了CO2注入地层后的地质压力、储层物性变化和CO2运移规律等。结果表明,在CO2注入的10年间,CO2的注入提高了整个地层压力,高压场以注入井为中心呈现梯度递减向四周扩大。储层的孔渗性随着CO2的注入逐渐增大,而盖层物性未发生明显变化。CO2羽流主要在中间储层中运移,未突破上下盖层。此外,通过模拟研究发现嘉陵江组的CO2总封存量为3.211×107 kg。结果说明嘉陵江组所选层位可有效封存CO2。
Abstract:：A three-dimensional geological model was established based on the Jialingjiang formation in Luojiazhai, and FLAC3D-TOUGHREACT was used to simulate and evaluate the formation pressure, reservoir physical properties and CO2 migration law after CO2 injection into the formation. The results showed that during the 10 years of CO2 injection, the injection of CO2 increased the whole formation pressure, and the high-pressure field showed a gradient decrease centered on the injection well and expanded around. The porosity and permeability of the reservoir gradually increased with the injection of CO2, while the physical properties of the cap rock did not change significantly. The CO2 plume mainly migrated in the intermediate reservoir and did not break through the cap rocks. The simulation study showed that the total CO2 storage capacity of Jialingjiang formation was 3.211 × 107 kg. Results indicated that the selected layers of the Jialingjiang Formation can effectively store CO2.
