摘要
四川盆地气田气藏大部分都是有水气藏,由于气藏产水,对气井的生产造成严重的危害,产量急剧递减,水淹停产井逐年增多,成为气田生产的突出矛盾。20多年来,四川盆地气田的采气工作者,经过不懈努力,发展了一套具有四川盆地特色的排水采气工艺技术。介绍了四川盆地排水采气工艺技术的研究历程,对排水采气工艺技术的研究与应用取得的成果进行了总结,并对今后的技术发展提出了建议。
Most reservoirs in Sichuan gas field are water-yielding ones.Because of the producing water,the wells' flowing capacity is weakened rapidly and the drowned wells are increased year after year,thus causing serious harm on the gas production.Over past 20 years,a series drainage gas recovery technology sui-ted for Sichuan gas field has been developed,it improved the de-velopment efficiency of the reservoirs.This paper introduced the study and application of the drainage gas recovery technology,pointed out the problems existent in the reservoirs,as well as the suggestions on them.
