The problem of produc ing w ater o f the gas w ells is one of
the m ost important fac to rs, wh ich affects the production
ab ility of the gas w ells and the sca le of the gas fie ld. J ingb ian
gas reservo ir is a fixed vo lum e and it has no t wa ter in side or
bottom, but has a re latively r ich wa ter zone, which is
restr icted by m any factors and has a bad e ffect to the gas
w e lls􀀁 production. The gas w e lls􀀁 production is low er and
descend ing is higher. There is wa ter in som e gas w ells and
there are som e differences in the amount of wa ter. Th is paper
analyses the production cha racte ristics by class ify ing of the
gas w e lls, stud ies the distributing o f r ich w ater zones, the
reasons o f fo rma tion and the e ffects to the gas w e lls, rea lizes
the degree o f the effec t on the g as fie ld exp lo itation because of
w ater production, studies the reasonab le w ork sy stem in
