一种适合于低渗低压气井修井的暂堵型压井流体及制备方法
摘要：
本发明提供了一种适合于低渗低压气井修井的暂堵型压井流体，由以下重量份数的组分制备而成：水1000份，十二烷基苯磺酸钠3～5份，十二烷脂肪醇2～3份，羧甲基纤维素钠25～30份，聚丙烯酰胺25～30份，碱式碳酸锌10～20份，抗温稳定剂15～20份。本发明提供的这种适合于低渗低压气井修井的暂堵型压井流体，具有封堵漏失地层效果好、温度稳定性好(抗120℃)、储层伤害能力低等优点。
摘要（英）：

The invention provides a temporary plugging type well control fluid suitable for repairing a low-permeability low-pressure gas well. The temporary plugging type well control fluid is prepared from the following components in parts by weight: 1000 parts of water, 3 to 5 parts of sodium dodecyl benzene sulfonate, 2 to 3 parts of dodecyl fatty alcohol, 25 to 30 parts of sodium carboxymethyl cellulose, 25 to 30 parts of polyacrylamide, 10 to 20 parts of basic zinc carbonate and 15 to 20 parts of temperature-resistant stabilizer. The temporary plugging type well control fluid suitable for repairing the low-permeability low-pressure gas well, provided by the invention, has the advantages of good loss zone blocking effect, good temperature stability (temperature resistance is up to 120 DEG C), low reservoir damage ability and the like.
