摘　　要：东胜气田近年来上产步伐不断加快,为了满足油藏整体开发的部署要求,减小投资成本,节约搬迁时间,加快气井投产贡献,多以丛式井组的方式部署井位,同井场多口井相继钻井、射孔、压裂、试气、投产,但部分丛式井组内,即使单井投产层位、物性、储层改造规模一致,但生产情况仍会存在较大差异。东胜气田锦30井区的J30-4-2丛式井组即存在该问题,通过对压裂、试气、生产资料的系统综合分析对比,结合压恢测试资料,得出结论是J30-4-2井生产低效原因是近井地带受到污染,渗流通道不顺畅。In recent years,the pace of production in Dongsheng gas field has been accelerating.In order to meet the deployment requirements of the overall development of the reservoir,reduce the investment cost,save the relocation time and accelerate the contribution of gas well production,the well locations are deployed in the form of cluster well groups.Several wells have been drilled,perforated,fractured,gas tested and put into production successively,but in some cluster well groups,even if the production horizon,physical properties and reservoir reconstruction scale of single wells are the same,there will still be great differences in production.This problem exists in J30-4-2 slave well cluster in jin30 well block of Dongsheng gas field.Through the systematic comprehensive analysis and comparison of fracturing,gas testing and production data,combined with the pressure recovery test data.It is concluded that the low efficiency of J30-4-2 well production is due to the pollution near the well and the unsmooth seepage channel.
