Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Based on streamline simulation, water breakthrough of fractured horizontal wells is analyzed, and a new fractured horizontal well is proposed. Its adaptability in different well patterns is evaluated from the aspects of productivity, oil recovery, water cut and swept area. The results show that for the horizontal wells with equal fracture length, the water breakthrough time of edge fractures is earlier and the water cut rises rapidly. Both the new and conventional well types in the staggered well pattern have almost the same development. But in the diamond and rectangle well patterns, the new well type B can expand relative swept area and improve oil recovery with significant reduction of water cut. 30-year relative swept area and recovery of the two well patterns are increased by 6% (10%) and 0.96% (1.6%) respectively, and the final recovery (water cut = 95%) is enhanced by 1.05% and 1.5%.
