特低渗砂岩油层保护剂RP-3的研制与应用

THE DEVELOPMENT AND APPLICATION OF A FORMATION PROTECTION AGENT RP-3 FOR LOW PERMEABLE SANDSTONE

    摘要
  • 摘要: 桐21断块为低孔、特低渗砂岩储层,储层污染比较严重。研究认为,储层伤害的主要原因是水敏和水锁。针对储层这一特点,研制了油层保护剂RP-3。现场应用13口井,其中试油6口,平均单井日增原油1.53t,平均单井日减水量6.54m3,取得了良好的保护油层效果。

     

    Abstract: Block Tong-21 is a low porous, low permeable sandstone reservoir, and severe formation contamination is detected. The main causes of formation damage in this area are water sensitivity and water blocking, thus a formation protection agent RP-3 is developed to solve these problems. This product is used in 13 well, in which 6 of them are tested, and the daily oil production increases by 1.53t, and water production lowers by 6.54m3.
