摘要

在向低压油田注入二氧化碳时,焦耳-汤姆逊冷却会导致水合物形成导致注入能力受损。考虑焦耳-汤姆逊冷却和储层与邻近地层之间的非稳态延迟热交换,本文提出了轴对称流动模型,该模型可用于预测CO2注入多孔地层过程中温度和CO2锋的传播。通过与准二维热导解析解的比较,验证了一维流解的正确性。非稳态热交换导致温度锋随时间无限制地向储热器内扩散。温度分布表现为从注入温度开始温度下降到最小值,然后在温度前沿急剧上升到初始储层温度。该解决方案允许在co2 -水相图中绘制固定时刻的温度-压力(T-P)曲线。通过改变注入参数(如注入速率),T-P轨迹可以评估水合物的形成。

Joule-Thomson Cooling During CO2 Injection Under Unsteady-State Delayed Heat Exchange
Joule-Thomson cooling during CO2 injection into low-pressure fields can lead to injectivity impairment due to hydrate formation. This paper presents axial-symmetric flow model, which can be used to predict propagation of temperature and CO2 fronts during CO2 injection into porous formations accounting for Joule-Thomson cooling and unsteady-state delayed heat exchange between the reservoir and the adjacent formations. The solution of the 1D flow is validated by comparing with the quasi 2D analytical heat-conductivity solution. The non-steady state heat exchange results in a temperature front that propagates without limit into the reservoir with time. The temperature profiles exhibit a temperature decrease from the injected temperature to a minimum value, followed by a sharp increase to initial reservoir temperature on the temperature front. The solution allows plotting temperature-pressure (T-P) profiles at fixed moments in the CO2-water phase diagram. By changing injection parameters such as injection rate, the T-P trajectories allow for assessment of hydrate formation.

期刊介绍: Water Resources Research (WRR) is an interdisciplinary journal that focuses on hydrology and water resources. It publishes original research in the natural and social sciences of water. It emphasizes the role of water in the Earth system, including physical, chemical, biological, and ecological processes in water resources research and management, including social, policy, and public health implications. It encompasses observational, experimental, theoretical, analytical, numerical, and data-driven approaches that advance the science of water and its management. Submissions are evaluated for their novelty, accuracy, significance, and broader implications of the findings.
