| Abstract: | The mature oil fields early developed in Daqing have entered late period of specially high water cut stage, and it is believed that a great amount of remaining oil is trapped in thick zones. Now horizontal wells can be drilled at lower cost, it is becoming more feasible to tap the remaining oil in the upper part of thick pay zones. Sand bodies penetration percentage is pertinent to following 3 factors; accurate prediction of the top microstructure of sand bodies, accurate landing of horizontal wells and adjustment of horizontal section drilling trajectory. Watered out problems of horizontal wells in thick oil pay zones concern with the techniques about avoiding watered out in thick pay zones and the developing principles. New suggestions about application of horizontal wells for EOR in Daqing mature oil fields are established. |
