Abstract: Since Block Lun 16 of Baise Oilfield has stepped into high water cut production phase, an effective profile control/water shutoff technology was applied to improve oil recovery. On the basis of numerous Lab experiments, a new clay HPAM agent and its concentration adapted to Block Lun 16 reservoir charac-
teristic were selected to block the distant larger reservoir chan-nels in order to adjust profile control. After the practical appli-cation of the new agent to a couple of well groups in Block Lun 16 of Baise Oilfield, the oil rate increased remarkably while the water cut declined, which will be a successful experience for the whole oilfield to solve the profile control/water shutoff problem.

Key words: Baise Oilfield, profile control, water shutoff, core testing, EOR
