摘要: 目前,油藏已经成为CO2 埋存的重要场所,向油藏注入CO2 的同时可以提高原油采收率。根据延长油田靖边CO2 试验区储层物性特征,利用构造地层埋存、束缚埋存、溶解埋存及矿化埋存等机理,考虑CO2 在原油中溶解、CO2 在地层水中溶解及自由气的埋存,建立评价CO2 埋存量的模型,通过所建立的模型可以评价延长油田
靖边CO2 试验区埋存潜力。模型应用结果表明,靖边CO2 试验区CO2 埋存量可达209.879×104t,储层CO2 埋存量大,具有非常好的埋存潜力,为延长油田进行CO2 驱提供了重要的指导。

Abstract:

Oil reservoir has become an important way for CO2 storage, while the injection of CO2 to reservoir can also improve the oil recovery. According to Yanchang oilfield reservoir characteristics, an evaluation model for CO2 storage was established using the formation storage, bound storage, dissolved storage and mineralization mechanism. The model was established under the consideration of CO2 dissolution in the oil, CO2 dissolution in formation water and free gas storage. The model was used to evaluate the CO2 storage potential for Yanchang oilfield. The results show that the model can predict reservoir storage capacity, and the reservoir CO2 storage stock is about 209.879×104 t. The reservoir shows very good storage potential, which can provide important basis for CO2 displacement of Yanchang oilfield.

Key words: CO2, Yanchang oilfield, Storage potential, Evaluation model
