The article discusses the various stimulation techniques used to improve the production performance of hydrate reservoirs. Hydraulic fracturing is identified as the leading technique, with near-well stimulation and chemical stimulation as auxiliary and supplementary techniques, respectively. The article highlights the research on near-well stimulation, including the washout mechanisms and laws of high-pressure water jet on hydrate deposits. The potential of CO₂ caprock reconstruction and methanol huff and puff to improve production performance is also explored, with an analysis of the feasibility of CO₂ caprock reconstruction and storage. The article concludes that strengthening the reservoir stimulation theory and technology system is necessary to accelerate the industrialization process of hydrate resources.
