在低渗透油田的开发中,水平井注水不仅可以降低注入压力、增大注入量、产生丰富的热裂缝,而且在某种程度上还可近似为线性驱动,极大地提高了驱油效率。水平井注水井网产能计算是水平井注水井网设计的理论基础,根据推导的公式,以五点井网为例,对产能的各种影响因素进行了分析,为水平井注水井网设计提供一定的理论基础。 In the development of low permeability oilfields, injection of horizontal well water can not only reduce the injection pressure, increase the injection volume, produce rich hot cracks, but also can approximate the linear drive to some extent, greatly improving the oil displacement efficiency. The calculation of horizontal well water injection well network productivity is the theoretical basis of horizontal well injection well pattern design. According to the derived formula, taking five-point well pattern as an example, various influencing factors of production capacity are analyzed, providing the design of horizontal well injection well pattern A certain theoretical basis.
