摘要
本文对泥浆冷却系统进行了详细介绍。泥浆冷却系统由冷凝机制冷载冷剂回路和泥浆冷却两个回路组成,泥浆和载冷剂在同轴套管式换热器内通过逆向流动实现热交换。本套系统在漠河盆地天然气水合物钻探施工中进行了应用,此次水合物钻探从8月16日开始,耗时2个月,完成了一个终孔直径Φ108mm、深度为500m的钻孔。泥浆冷却系统良好的泥浆制冷效果保证了漠河盆地天然气水合物钻探施工的顺利进行,同时为未来大规模天然气水合物的勘探以及开采工作提供了有效的技术保障。
In this paper a mud cooling system is described in detail. This system consists of two loops, which are the cooling refrigerant loop and mud cooling loop. Mud and refrigerant exchange heat in the coaxial heat exchanger is achieved by reverse flow. This system has been applied to gas hydrate exploration in the Mohe basin with permafrost, which began in Augustl6 and took two months to finish the whole exploration. At the end, a 500m hole of Ф08mm was drilled. On account of the mud cooling system＇ s perfect cooling effect, the gas hydrate exploration in the Mohe basin was conducted smoothly . In addition the mud cooling system will provide an effective technical support for future large-scale exploitation and exploitation of gas hydrate.
