In formula,--- constant, well spacing coefficient；--- coefficient of heterogeneity between constant, two oil wells；β1、β2Respectively
For constant, the ratio of two mouthfuls of well quantity delivereds and yield is represented；
According to dynamic analysis, it is known that the responding time of two oil wells is respectively t in same well group1=t01、t2=t02, opened from water injection well
The average product for this period that beginning water filling takes effect to oil well respectively Q01、Q02, i.e. Q1=Q01、Q2=Q02, therefore, it is possible to obtain
Coefficient of relationship β value is between the well of two oil wells：

Wherein,--- constant, well spacing coefficient；
When two oil wells are shown in injection water simultaneously, then：
t′1/t′2=α β (Q2/Q1)=1
Q2/Q1=α β (8)
Wherein, t '1、t′2Two mouthfuls of wells are shown in injection water time, d, and t ' in respectively same well group1=t '2；
It is capable of determining that by (8) formula in each well group so that any two oil well is while be shown in yield ratio required during injection water.
