| 摘 要： | 低渗油藏油水渗流时启动压力现象的存在，使注采井距理论上存在一个最大值，通过不同渗透率岩样启动压力梯度的研究，结合单井产量公式，可以计算出给定注采压差条件下低渗油藏的最大注采井距，从而为合理注采井网的部署提供依据。

| Abstract: | The exsiting of oil or water's start-up pressure makes that producer-injector spacing havs a maximum value in low-pressure reservior's percolation.Through the research of start-up pressure gradient of different-pemeability rock samples,combining sigle-well prodution formula,can calculate the biggest producer-injector spacing when gived certain injection-production pressure difference.So gist provided is to rational well pattern deployment. |
