基于吸附式储冷技术的深井钻探设备冷却系统
Cooling system for deep well drilling equipment based on adsorption cold storage technology
摘要
Abstract
With the gradual depletion of conventional oil and gas resources globally,mankind has started to focus on the exploitation of unconventional oil and gas resources.As a significant unconventional resource,deep oil and gas hold immense exploitation potential.However,at present,ultra-deep well drilling technology remains imperfect,and the process encounters technical challenges,such as drilling equipment's inability to endure the high temperatures of these wells.Adsorption-type cold storage equipment,characterized by its small size,high cold storage density,wide working temperature range,and vibration resistance,stands as an ideal solution for cooling and temperature maintenance in high and ultra-high temperature drilling operations.To complement the drilling equipment,a modular cylindrical adsorption cold storage system was designed.This system employs a NaY-type zeolite molecular sieve-water pair and features an adsorption bed length of 0.87 m.In a downhole environment of 200℃,the system can maintain the temperature of electronic components in the drilling equipment at 125℃for 30 h,meeting the demands of a single downhole operation.This innovation offers a fresh perspective for the design of high-temperature-resistant drilling equipment.关键词
