摘　　要：低渗透油层低的单井采油能力和吸水能力注定了低渗透油藏必须采用密井网和油水井数比低的井网。对于井间干扰的传统认识需要更新:井间干扰是注水见效的必要条件;井距缩小单井产量不会降低;注水井的吸水能力是选择合理井网井距的关键;井网对"油砂体"的控制也应向控制“流动单元”转变。Based on low productivity and injectivity of a well for low permeability reservoirs,close well pattern and well spacing must be performed.Old conventional ideas should be given up while new ideas should be established:interference among wells is requirement of injection results;reducing well spacing will not affect unit well productivity ;reasonable well pattern and spacing depend on injection ability of a injector;well pattern controls 'flow system' not 'oil sand bank'.
