摘　　要：在油气井生产过程中,有些油气井关井测压往往遇到困难。二流量试井技术不需要关井,只需要改变工作制度来改变产量,即可取得准确的地层参数资料。应用试井软件的分流量解释功能,可以有效的解决二流量资料的解释,并通过二项式产能方程回归计算地层压力,所获得参数结果和关井测压解释结果吻合度高,能够满足实际生产需要。Some oil or gas wells are difficult to be shut in for pressure measurement. Accurate reservoir pressure and other data can be obtained from two-flow well test which doesn't need to shut in the tested well but need to flow it twice with different rates. The data interpretation can be done by well test interpretation software and the reservoir pressure obtained this way is consistent with the measured one which can meet the requirement of application.
