Fault-block Ze70 of Huabei oilfield is during the period of middle-high water cut of water flooding development, but the oil recovery is very low, only 10.8 percent which illustrates unbalanced development state of this complex fault block reservoir. According to the features of polymeric microspheres deep profile control technique, parameters were studied including polymeric microspheres solid content, grain size and mean pore diameter ratio and breakthrough migration ability. On the basis of these, solid content, temperature and salt resistance ability, breakthrough migration ability and oil-displacement capacity of 6 polymeric microspheres were evaluated by simulating the reservoir conditions of Fault-block Ze70 indoor. Favorable geological conditions for polymeric microspheres were selected, and construction design scheme was drawn up. Field application in Fault-block Ze70 indicated that average pressure elevation of each well is up to 2.4 MPa, and 11 out of 17 wells connected by one line were showed significant flooding effect with effectiveness of 64.7%. This technique offers valuable reference and reliable guide for similar reservoir development. [ABSTRACT FROM AUTHOR]
