With the modified definition, the single phase flow's water flooding response and its affecting factors in a five-spot water flooding pattern are studied by numerical simulations when the production well is an infinite conductivity vertical fracture well and the injection well is a straight well. Permeability greatly affects the water flooding response, and water flooding response sharply increases with decrease of permeability, especially when the permeability is smaller than 10 md. The bigger the well spacing, the longer the water flooding response, and the increase of water flooding response is getting faster with spacing's increase. The higher the injection volume, the shorter the water flooding response, and the decrease of water flooding response is getting smaller with injection volume's increase. Measures can be taken such as injection ahead of time, with smaller well spacing and higher injection volume when permeability is too small., authors=null, authorsList=null, authorCompany=null,

articleAbstract=压力在地层中的传播是瞬间完成的，基于此，重新定义注水见效时间为受到注水压力影响的采油井产能与弹性开采的采油井产能之差，达到弹性开采的采油井产能的1%时所需的时间。从新的定义出发，运用数值模拟方法研究了5点注采井网系统中，采油井为无限导流垂直裂缝井、注水井为直井的单相流注水见效问题及其影响因素。渗透率对注水见效时间影响很大，尤其当渗透率小于10 md时，注水见效时间随着渗透率的减小急剧增加；随着井距的增加，见效时间增加，井距等量增加，见效时间增加越来越大；随着注水强度增加，见效时间减小，注水强度等量增加，见效时间减少越来越小；当渗透率很小时，可以考虑超前注水，适当减小井距、加大注水强度。, authors=刘华林,熊伟,高树生,刘华勋, authorsList=刘华林;熊伟;高树生;刘华勋,
