摘　　要：结合现场实践探讨了在异常高温高压气井完井关键技术及安全采输中油管直径优化问题解决方案、地面工艺流程、节流降压、水合物防止、气井及生产系统的完整性等方面的关键技术,实践表明以上技术能较好符合现场要求,可为类似异常高温高压气井开采提供参考和借鉴。A multi-function JHTR true triaxial stress clamp was developed for simulating hydrocarbon reservoirs and coal reservoirs,it could be used for solving the problems of scientifically and truly simulating the laws of permeability changes,the process of dynamic pollution of drilling fluids in under-balanced,normal pressure differential and balanced drillings and implementing the integration of simulating the formation damage and filtration test,it also could be used to solve the problem of stress effect induced in sample clamping,by which its technical shortcomings existed both internally and externally were avoided.It provides an effective means for core(coal) permeability testing and studying the law of mechanic parameter changes under the condition of true triaxial stress in the reservoirs.The clamp is flexible operation and easy application and an indispensable tool for core testing.
