| 摘 要： | 长宁页岩气藏采用丛式水平井进行开采,产出水为压裂残液、CaCl_2水型、矿化度29~53g/L。针对该水质特点及井型情况,优选了发泡力大于160mm、5min稳泡性大于250mm、携液量大于150mL/15min的起泡剂,研发了橇装式自动起消泡剂加注装置。在H3-1和H3-2井中成功进行了现场应用,合计增产气量0.49×10~4 m~3/d(增加26.9%),增产水量6.14m~3/d(增加1.17倍),表明泡沫排水采气技术对长宁页岩气井有很好的适应性。

| Abstract: | The well type of Changning shale gas reservoir is cluster horizontal well. The water producing from the well is fracturing fluid residue, the type of it is CaCl2, the salinity of it is between 29 g/L and 53 g/L. Aiming to the characteristic of water component and well type, the authors selected a foam agent which the foaming ability is greater than 160mm, 5 min foam steady ability is greater than 250 mm, foam-carrying capability is greater than 150 mL/15min, and developed a skid-mounted filling device for automatic foaming and de-foaming agent.The foaming agent and device have been successfully used in the wells of H3-1 and H3-2. The total increase of gas production is 0.49×104 m3/d, which increased by 26.9%; the total increase of liquid production is 6.14 m3/d, which increased by 117%. It is confirmed that the foam-dewatering treatment has a good adaptability of Changing shale gas well. |
