摘　　要：针对长庆靖边气田在开发过程中存在气井出水,严重影响开发效益的问题,根据该气田气井产水现状,总结出了气井的产水规律。按照水气比的变化,将其归纳为水气比下降、水气比稳定、水气比升高等三种类型,在此基础上,通过综合分析和研究,提出了不同类型产水气井进行有效开发的具体措施。位于相对富水区的井,完善开发井网;生产过程中水气比下降的井,尽量避免关井,以正常的合理产量连续开井生产,利用自身能量将地层水带出,保持稳定生产;水气比较稳定的井,维持气井正常生产;气水比上升的井,严格控制生产压差,控制水侵速度,以减少水侵量、提高采收率。将该研究应用于长庆靖边气田产水气井的开发,取得显著的经济效益。Aiming to the problem of gas wells producing water in the exploitation process of Qingbian gas field, which effects the exploitation benefit severely, according to the present status of gas wells producing water, the water-producing law of gas wells is summed up. With the variation of water-gas ratio, the gas wells producing water are divided into 3 types: i. e. water-gas ratio decreasing, water-gas ratio stabilizing, and water-gas ratio increasing. Based on that, by integrated analysis and study, the concrete measures are proposed for the gas wells producing water of different types to be exploited effectively. As for the wells lying in the zone with relative rich water, the countermeasures are to improve the production well pattern; As for the wells with water-gas ratio decreasing, to avoid well shut-in as much as possible and keep continuous running with normal and reasonable production to carry the formation water out by itself energy and maintain the stable production. As for the wells with water-gas ratio stabilizing, to maintain the normal production of gas wells. As for the wells with water-gas ratio increasing, to seriously control the production pressure difference and the water-invaded rate to decrease the water influx and improve the recovery factor. Applying the study fruits to the exploitation of gas wells producing water in Qingbian gas field, the obvious economic benefit has been achieved.
