摘　　要：桐 2 1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 1.5 3t,平均单井日减水量 6 .5 4m3,取得了良好的保护油层效果。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 protecti on agent RP-3 is developed to solve these problems. This product is used in 13 w ell, in which 6 of them are tested, and the daily oil production increases by 1. 53t, and water production lowers by 6.54m 3.
