The invention relates to the field of gas field development, in particular to an early identification method for gas well shaft accumulated liquid of a low-permeability carbonatite gas reservoir. According to the method, the basis can be provided for gas well drainage gas recovery measure occasion and mode selection, and the irreversible damage to reservoir by the well shaft accumulated liquid isreduced; the method is wide in application range, aiming at the situations of limited adaptability as well as hysteretic judgment and recognition of the existing identification method for gas well shaft accumulated liquid of low-permeability carbonatite gas reservoir, the gas well shaft accumulated liquid can be rapidly and accurately identified by utilizing conventional dynamic production materials, the problems such as application difficulties caused by limited adaptability, hysteretic judgment and recognition and multiple wells of the identification method for gas well shaft accumulated liquid of low-permeability carbonatite gas reservoir can be solved, the well number and the range of timely judgment and recognition of the well shaft accumulated liquid can be greatly expanded, and theapplication can prove that the method is accurate and quick, can save a lot of manpower and financial resources, and has great practical value and economic value.
