Drilling Procedure Control and Sampling of Gas Hydrates

摘要:

分析了天然气水合物的稳定条件及对钻进过程的影响,讨论了天然气水合物的钻进泥浆控制策略和取样(心)技术,同时介绍了大洋钻探(0DP)使用的保压取样器PCS.

Abstract:

The ability conditions for gas hydrates and their effects on drilling process were analyzed. The control strategy of mud and the techniques of sampling and/or coring used in gas hydrate drilling also were discussed. Meanwhile the pressure core sampler used by ODP was introduced.
