摘要: |
川西白马庙蓬莱镇组浅层气藏气井大都为低产有水气井,产气量为1000~3000m^3/d。由于产气量降低后气井自身带液能力下降,一些气井只能间歇开采甚至被水淹停产,需要实施泡排工艺以维持气井正常生产。白浅36井和白浅33井是此类气井中有代表性的气井,通过对两井的泡沫排水采气工艺的研究和现场试验,确定了适合的起泡剂,并取得了很好的现场泡排试验效果,使原来间歇生产的气井恢复了连续生产。现场试验表明,对于1000m左右的浅井,在气产量低至1000m^3/d左右时,仍适合采取泡排工艺;因水淹停产的产水量较少的气井,采用多次加注适合的起泡剂、放喷带液、关井复压的操作,可以逐渐恢复气井的生产。 |

Abstract: |
There are many low-yield and producing water gas wells in the Baimamiao gas field of the western Sichuan province. These well's output is between 1000~3000 m3/d and the depth is 750~1500 m. Because the liquid-producing capacity is falling down with the ou |
