从南翼山E₃2凝析气藏地质特征、措施作业及试采特征分析入手，提出了南翼山E₃2凝析气藏气水关系模型，分析了气藏水淹原因，总结了该凝析气藏开发的一些经验及教训，指出人工巨型水力压裂是该凝析气藏水淹的潜在原因，不合理配产采气是气井水淹的诱导因素，不合理井位部署是缩短气藏无水采气期的主要原因。指出层状气水层间互气藏或气水层邻近的气藏，特别是层状裂缝型气藏，不宜压裂增产采气，同时提出该类气藏开发井位部署应远离人工裂缝，明确指出控制采气速度特别是人工裂缝附近井的采气速度有利于该类气藏的高效开发。该气藏后期生产特征表明，本文分析方法正确，结果可靠，对同类型气藏的科学开发具有一定的指导和借鉴意义。

CAUSES FOR WATERFLOODING E32 CONDENSATE GAS RESERVOIR IN NANYISHAN FIELD IN CHAIDAMU BASIN

On the basis of analyzing the geological characteristics, stimulation treatments and production tests of E 3 2 condensate gas reservoir, the gas water relation model of the reservoir in Nanyishan field is put forward; the causes for waterflooding the gas reservoir are analyzed; and some experiences and lessons of developing the reservoir are summarized in the paper. It is pointed out that the large scale hydrafrac was the potential cause for waterflooding the condensate gas reservoir; unreasonable gas distribution and production were the induced causes for waterflooding gas wells; and unreasonable well pattern was the principal cause for shortening the water free gas production period of the gas reservoir. It is also pointed out that the stimulation treatment by fracturing is not suitable for the gas reservoir with interbedded gas water layers or the ones being adjacent to water layers, especially for the layered fractured gas reservoirs; the development well pattern arrangement should keep away from artificial fractures; and it is beneficial to the high efficiency development of such kind of gas reservoirs to control the rate of gas production of the gas wells, especially the ones nearby the artificial fractures. According to the later production characteristics of the gas reservoir, it was indicated that the analysis method in this paper is correct, its result being reliable, which is of certainly guiding and referable significance for scientifically developing the same kind of gas reservoirs.
