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.
