| 摘 要： | 根据低渗透油藏不稳定试井的曲线拟合可以确定启动压力梯度、渗透率等参数,并可以确定启动压力梯度与渗透率之间的关系式,再根据低渗透油藏渗流理论可以得到低渗透油藏的极限井距的公式,从而确定极限井距。

| Abstract: | According to the unstable well test curve fitting in low permeability reservoirs,some parameters such as the start-up pressure gradient,permeability and so on were determined,then equation between start-up pressure gradient and permeability was gained.According to the filtration theory in low permeability reservoirs,limit injection-production well spacing equation of low permeability reservoirs was gained,and limit injection-production well spacing was determined. |
