摘要

海底二氧化碳（CO

）地质封存技术已成为目前碳封存、碳中和研究的热点，我国南海北部海底沉积层中存在CO

水合物形成的有利空间和温压条件，在裂隙和孔隙中形成CO

水合物，能够阻挡CO

进一步向上运移而产生自封堵能力。然而，目前裂隙中CO

水合物封堵效果与失稳条件仍不明确。采用高压低温水合物生长失稳可视化实验平台，模拟2℃、3～4 MPa的海底沉积盖层条件，观测裂隙中CO

水合物的形成与注水增压失稳过程，利用突破压力、突破压差、持续时间、失稳起始阶段渗透率及封堵率为指标对水合物失稳条件与封堵效果进行了研究。研究结果表明，裂隙中水合物的形成经历成核、扩张、成型与聚集4个阶段；裂隙中形成的水合物能够高效地封堵水和CO

等流体的迁移，但在流体压力逐渐增加达到临界突破压力时开始出现失稳现象，水合物的失稳经历粒度退化与表面摩擦破坏2个阶段，水合物团块内核部先失稳，在水合物表面未破裂前可保持封堵状态；裂隙中水合物失稳的突破压力为6.414～6.966 MPa，突破压差为2.403～3.203 MPa，决定水合物突破压力的关键因素是温度和压力条件，而流速的效应则主要体现在调节水合物进入失稳状态的具体时间；在3～4 MPa的海底沉积盖层条件下，裂隙模型中水合物封堵率为99.0%～99.6%，失稳起始阶段渗透率为0.555×10

水合物层之下压力与海底实际压力之差小于2 MPa，以保持水合物的封堵效果。研究结果为南海类似条件下CO

Abstract

ObjectiveSeabed carbon dioxide (CO2) geological sequestration technology has gained popularity in the fields of carbon sequestration and carbon neutralization. In the northern South China Sea

favorable conditions for the formation of CO2 hydrates exist in seabed sediments

where hydrates forming in cracks and pores may block the further upward migration of CO2 and generate self-sealing capacities. However

the effects of CO2 leakage in fractures and the instability of hydrate plugging remain unclear. MethodsA visualization experimental platform for hydrate growth and the instability process under water injection supercharging at high pressure and low temperature was used to observe CO2 hydrate formation. The platform simulated the conditions of seafloor sedimentary cover at 2℃ and 3-4 MPa

and evaluated hydrate instability and plugging effects using parameters of breakthrough pressure

breakthrough pressure difference

duration

permeability coefficient at the initial instability stage

and plugging rate. ResultsThe experimental results show that hydrate formation proceeds through four stages: Nucleation

expansion

formation

and aggregation. Hydrates formed in cracks effectively block the migration of fluids such as water and CO2; however

instability begins when fluid pressure increases and reaches the critical breakthrough pressure. The instability process can be divided into two stages: Particle size degradation and surface friction failure. The hydrate mass core becomes unstable first

while the sealing state persists until the surface of the hydrate fails due to friction. The breakthrough pressure ranges from 6.414 to 6.966 MPa

and the breakthrough pressure difference is between 2.403 and 3.203 MPa. Hydrate instability is primarily influenced by flow rate

with the flow rate affecting the instability rate through interface effects. The breakthrough pressure of hydrates is mainly determined by temperature and pressure

while flow rate influences the exact time when hydrates enter instability. At 3-4 MPa seafloor sedimentary cover

the sealing rate is 99.0%-99.6%

and the permeability coefficient at the initial instability stage ranges from 0.555×10−3 to 1.260×10−3 μm2. ConclusionThe experimental results offer a reference for risk assessments of overlying layers in similar conditions in the South China Sea for CO2 seabed geological sequestration. To maintain the sealing effect of CO2 hydrates

the pressure difference between the capped hydrate layer and the actual seabed pressure should be less than 2 MPa.
