Research of development plan for Y11 fractured low permeable lithologic oil pool

Abstract
Through the analysis of the characteristics of fractures in fractured-low permeability reservoir and of the feasibility of different well patterns,using Eclipse to simulate a couple of programs with different fracture parameter,well pattern and water flooding regime,and combing the characteristics of channel deposit,this paper studies the well patterns used in fractured-low permeability reservoir in Y11 and proposes that the five-spot well pattern is profitable practice applied in fractured-low permeability reservoir.Meanwhile,it also studies and illustrates the practical well the intersection angle between the direction of fractures and that of well lines.The practice discussed in this paper has seen a good outcome when it is applied in designing well pattern for fractured-low permeability reservoir of Y11.It offers support in well pattern optimizing for reservoirs with the same characteristics.
