Abstract: In the early stage of development of weak water drive gas reservoirs,the water invasion characteristics are not obvious,so it is difficult to identify them. Water monitoring and water-gas ratio curve analysis were often used to identify water invasion characteristics of gas reservoirs,but these methods can only be used after formation water enters gas wells,which is not conducive to taking preventive measures in advance. Taking A gas reservoir with weak edge water energy in Sebei No. 2 gas field as an example,the early water invasion characteristics of gas reservoir were identified by introducing production indicator curve method,water storage volume coefficient method and apparent geological reserves method,and the curve characteristics under different recovery degrees were compared. The results show that the apparent geological reserve method is sensitive to water invasion of gas reservoirs,and the corresponding recovery degree is the lowest when the curve warping point occurs, which is 20% lower than the field experience method. The result of water invasion identified by the apparent geological reserve method is more reliable,and the water invasion characteristics of gas reservoirs can be found earlier. The research results have guiding significance for early identification of water invasion characteristics of weak water drive gas reservoirs without fracture development and relatively homogeneous porosity.

Key words: water drive gas reservoir identification, water storage volume coefficient method, production indicator curve method, apparent geological reserves method, Sebei gas field
