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。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.
