摘　　要：文章对大池干井气田石炭系气藏的龙头—吊钟坝、万顺场、磨盘场3 个高点的地层水治理效果进行了评价,结合各高点地层水治理方案与实际生产情况,对比认为吊钟坝高点北端的效果差,龙头—吊钟坝高点鞍部、万顺场高点、磨盘场高点效果好。同时,对产生治理效果差异的原因进行了分析,认为制定合理的治理方案是取得良好治理效果的前提;地层水治理措施的有效执行,是取得阶段较好治理效果的保证;不断根据出水气井的实际情况提前调整排水采气措施及相关配套工程,是取得最终较好治理效果的保证。根据目前气藏各气水井的实际情况,对下一步应采取的措施提出了恢复池27井工艺排水采气、调整池34和池61井的生产管串、做好池6井停止自喷生产后的工艺排水采气前期准备工作的建议。The results of formation water control are evaluated for the 3 highs of Longtou-Diaozhongba, Wanshunchang and Mopanchang in the Carboniferous gas reservoirs of Dachiganjing gas field. According to the program of formation water control for each high and real production, the comparison shows the result is poor for the north wall of Diaozhongba high and the results are good for the arch bend of Longtou-Diaozhongba high, Wanshunchang and Mopanchang highs. The reasons why the results are different are analyzed. It is thought making reasonable control program is the precondition to get good results. Effectively performing the control measures of formation water is the guarantee to get good stage results. With the real situation of the gas wells with water, continuously adjusting the measures of gas recovery by water drainage in advance is the guarantee to get good ultimate results. According to the current real situation of the every gas well with water, the suggestions are proposed for well Chi 27 to restore the process of gas recovery by water drainage; for wells Chi 34 and 61 to adjust the production string; and for well Chi 6 to make early preparations of gas recovery by water drainage after blowing stops.
