Abstract:According to the characteristics of existing environment and natures of gas hydrates, a new gas hydrates sampler with hole bottom freezing is developed. The sampling was realized by wire-line coring with liquid nitrogen as external cold source. The paper describes the freezing method, operating principle and the main structure features.
