| Abstract:In 2016, land gas hydrate trial-produce has been carried out successfully in Muli basin, Qinghai. It is the first time that the technology of horizontally butted well has been applied in gas hydrate trial-produce and remarkable results have been achieved. Complex stratum of drilling area brought great difficulty and risk to the horizontally butted well drilling. Drill pipe sticking appeared several times during the drilling process, this paper mainly introduces and analyzes in detail on the main reason of drill pipe sticking with the corresponding jam release methods. |
