油井分层注水倍数计算方法

运用水井纵向劈分方法,对B-Z油田3口水井对应5个小层进行劈分,将与油井连通的各水井水量劈分到连通层位上.运用水井平面劈分方法,对上述各区水井劈分到各层的产水量劈分到该层与水井连通的油井上,将各水井水量劈分到同一油井相同层位上的水量累加得到与水井连通油井的注水量.运用劈分结果计算出B-Z油田水井射开层位的累积注水倍数,对油田后续开发调整提供理论依据.

Computing Method of Separating Layer Water Injected Volume About Oil Wells

Applying the way of portrait output splitting of water well which can output splitting of water wells for that 3 water wells correspond to 5 perforation layers in B-Z oil field,which can make water yield that water wells connect to oil wells to connection layers.Applying the way of lateral output splitting for water well which can output splitting of water well for the above result,and accumulation water can get water injection rate of connecting to water wells,which is splitting water of every water wells to the same layers of one oil well.Applying the result of splitting can get which accumulation water injected volume of water wells correspond to layers in B-Z oil field,which can offer theoretical foundation for follow-up development and adjustment in oil field.
