摘要
针对天然气水合物储层环境,依托中国地质调查局地质调查项目"水域地层原位钻探取样器具设计及工艺研究"研制了海洋保温保压取样钻具。在室内试验的基础上,依次在浅水及深水对研制的钻具进行了功能性海试,改进后在1392 m深海进行了保温保压取样钻具功能性试验获得成功,为我国今后在海域天然气水合物勘探取样奠定了坚实的基础。
In view of the natural gas hydrate reservoir environment and relying on the research on the geological survey project＂the design and technical study on in-situ drilling and sampling equipments for the water formations＂,pressure-temperature core sampler for ocean was developed. On the basis of laboratory test,functional marine experiment was made on the developed drilling tools in shallow water and deep water successively. After the improvement,the functional test of pressure-temperature core sampler was made in 1392 m deep sea with success,which lays a solid foundation for the ocean exploration and sampling of natural gas hydrate in China.
