The Carboniferous gas reservoir in Longmen field is a medium-sized integral gs reservoir with a length of 24 km,widths of 1.0～2.5 km, a gas-bearing area of 45.1 km2 and payzone depths of 4 600～4 800 m. This gas reservoir is of edge water,its gas-water contact being at －4 420 m with a gas colunm height of 460 rn only. The heterageneity of the reservoir bed is serious and the gas reservoir geology and engineering con ditions are complicated. In order to detect the performance char acters of the reservoir as quickly as possible and to provid a set of detailed data for its development design, a great deal of reli able monitoring data were achieved in production test through adopting the most advanced high-accuracy electronic gauge and these methods of single-point or continuous testing at wellhead and bottomhole under open hole and shut-in well conditions in consideration of the gas reservoir geology and engineering prop erties. In a short time of less than a year, the interwell perfor mance relation,productivity and fluid properties of the reservoir were detected,a fair development effectiveness being achieved. These monitoring methods are of a certain referential signifi cance for quickening the production test work in the same gas fields.
