摘要

二氧化碳存入地下以地质封存方式进行减量是一项可行的工程手段。干燥情况下二氧化碳基本没有危害。然而在进行地质封存时，气井通常在地下水层、盐水层等潮湿的环境下操作，二氧化碳与水结合会形成碳酸，形成一个酸性的环境。实验室将API G级油井水泥添加包括飞灰、膨润土、重晶石与硅粉，在潮湿(100%)、饱和二氧化碳（常压，70 ℃）环境条件下养护28 d，研究其力学性能、化学成分及微观结构之间的关系。试验项目包括抗压强度、微观结构分析、X射线衍射及EDS扫描电镜。观察其养护样品发现，API G级添加飞灰的水泥呈现出最佳抗压强度及最深的碳化深度。而API G级添加膨润土的水泥现出最低抗压强度及最浅的碳化深度

Abstract

Storing CO2 underground by geological reservoirs is one of the ways to reduce atmospheric greenhouse gases. In the dry situation

CO2 has not harmed. But

when doing the geological reservoirs

the situation was often on the aquifers or deep saline aquifers. CO2 combined with water will become the carbonic acid (H2CO3) that makes cement alkalinity and compressive lower. This paper attempts to study the mechanical properties

chemical compositions

and microscopic structures of API G cements with different additives in the saturated-CO2 condition (atmospheric pressure

70 ℃). The additives under investigation include fly ash

bentonite

and barite with silicate that try to find better well cements in CO2 operation wells. The evolution of the mechanical properties including compressive strength and microscopic structure analysis including XRD

EDS

and SEM

were recorded over a period of 28 days. The carbonized depths of the samples over time were also observed. This study finds that the API G cement with fly ash displays the best compressive strength with deepest penetrating depth of carbonization. The API G cement with bentonite with higher water content has the lowest compressive strength with shallowest penetrating depth of carbonization.
