低渗透油田注水并压裂数值模拟研究

在改进的黑油模型基础上，建立了一种油、水两相三维油藏裂缝数值模型，可以对垂直裂缝油藏不同井网条件下注水井压裂效果进行数值模拟。以朝阳沟油田为例，在反九点法井网条件下，裂缝处于有利方位和不利方位时，对注水井压裂后的注入动态以及对应油井的生产动态的影响进行了分析，并与油田的实际生产动态进行了对比。研究结果为注水井压裂效果评价提供了一种手段，对于经济有效地进行低渗透油田注水开发具有实际意义。

The Numerical Simulation Research of Water Injection Well Fracturing in Low Permeability Oilfield

This paper introduces a kind of numerical simulation model of reservoir and fracture in oil water two phase three dimension, Which can proceed the numerical simulation on the stimulation result of water injection well fracturing in different well pattern in a reservoir with perpendicular fracture The paper gives an example in Chaoyanggou Oilfield, under the condition of inverted nine spot well pattern When the fracture is placed in a beneficial direction or in a disadvantageous direction, the effect of different fracture parameters to a water injection well injecting performance and relational oil well production performance is analyzed The simulation result has been contrasted with the real oil field production performance The research result in the paper provides an evaluation method for fracturing result of water injection well It has a practical significance on the economical and effective developing in the low permeability oilfield
