Nitrogen construction technology through(through)goaf wells
This paper studies the construction technology of the coalbed methane well in the goaf in the area,proposes the drilling technology of nitrogen construction,further optimizes the well structure of the drilling well and the safety issues that should be paid attention to in the process of nitrogen construction,and effectively solves the construction problems such as collapse,block drop and leakage in the sensitive layer of the goaf.It ensures the smooth construction of the horizontal well of coalbed methane in the goaf,further verifies the feasibility of the drilling technology,and has important guiding significance for the subsequent large-scale development of deep coalbed methane.
