| 摘 要： | 油藏工程理论及现场实践均表明,注水开发低渗油藏其注水方式和注采井数比对注水波及体积及水驱采收率有较大影响,通过对注水井水驱控制面积、单井控制面积与注采井数比进行了试探性回归分析,再结合谢尔卡乔夫公式,推导出了水驱采收率、驱油效率、井网指数、注采井数比与井网密度的关系式,从而建立了水驱油藏宏观井网密度公式.实例分析表明,该方法简单、实用,具有较高的准确性,不失为一种有效的方法. |

| Abstract: | Reservoir engineering theory and practice show injection method and recovery-injection well number ratio have a influence to injection-affect volume and injection recovery. Through the trial regression to the ratio of unit injection well control area, unit well control area and injection-production well number ratio and shirr formula and unit injection well volume rate of change increasing with unit injection well control area decreasing, then Waterflooding reservoir macroscopiea well spacing density formula can be established by which recovery, injectionproduction well number ratio, well pattern index, flushing efficiency and well spacing density are related. The example analysis indicated that this method is not only easy but useful. |
| Keywords: | well spacing density drive-oil efficiency recovery injection production well number ratio well index |
