Structure Design of Insulation Case for Large Diameter Insulating Well in Coalmine and the Casing Technology

摘要:

通过中平能化集团某矿的工程实践，研制出满足煤矿高地温矿井井下降温工程需要的钢基GFRP双层复合保温套管，对保温套管的下套管技术和保温套管接头保温方法进行了研究，对煤矿采用钻井的方法实施井下降温工程具有十分重要的意义。

Abstract:

Based on the engineering practice, a steel matrix GFRP double-layer composite insulating case for underground cooling engineering in high temperature coalmine was developed. The study was made on the casing technology and the insulating method of insulation case joint, which are very important for underground cooling engineering with drilling in coalmine.
