| 摘 要： | 合理的井网模式对低渗透油田开发的技术经济指标有很大的影响。以具有代表性的民北油田为研究对象，建立了概念模型并进行了数值模拟计算，同时研究了压裂裂缝对开发指标的影响。结果表明，井网密度、注采方式、工作制度以及油井加密转注时机等因素对该油田的开发效果均有明显的影响，在油田开发的中后期，要确定合理的井网模式和工作制度。对于低渗透油田来说，存在着合理的井网密度；对于具有方向渗透率的地层，井距与排距应有合适的比例。

| Abstract: | The optimum well pattern has some effects on the
technical and economical indexes in exploitation of Minbei Oil Field with low permeability.
Based on a typical reservoir with low permeability, a concept simulation model is developed
and applied to investigate the effects of well spacing density, injection production strategy and
optimum time of injection production well conversion on oilfield development. Furthermore, the
effects of hydraulic fractures in injection row on developing index were analyzed. The optimum
well pattern exists in low permeability oilfields. There should be a proper ratio of well spacing
to well array for the formation with directional permeability. |
