摘要(Abstract)：
对于低渗透储层试采井采用间歇定流压试采方式,可以防止井筒附近能量衰竭过快。但由于试采期间流动状态不断发生变化,不能采用稳定试井计算方法进行产能预测,因此建立了由地层参数计算间歇定流压试采方式下的压力计算方法,为此类方式试采定产提供科学依据。实例证明该方法计算结果与实际情况相符,可合理设计间歇定流压试采方式下的生产时间。
The batch fixed flow pressure production test method for low permeability reservoirs can prevent the excessive energy decline near the well bore.Due to the continuous change of flowing conditions during production test,the multi-point open flow potential test calculation procedure cannot be used for fluids rate forecast.Therefore,the pressure calculation procedure, which is calculated based on the formation parameters under the batch fixed flow pressure production test,has been established.This method can provide scientific support for production determination based on production test.
