利用多次环空测试资料进行油井试井解释新方法

New Well Test Interpretation Method by Using Multiple Times of Annulus Test Data

应用环空测试资料的流压段计算的油井各项参数,与压力恢复解释结果对比相对误差较小。对未出现径向流井试井解释,首次提出了稳定试井与不稳定试井联合解释技术。该技术解决了吉林油田低渗透储层的试井解释的难题,打开了吉林油田低渗透储层试井解释的新局面。

The relative error compared of every oil well parameters calculated from flow pressure by applying annulus testing data to interpretation result from pressure recovery is less.For the non-radial flow well test interpretation,the united technology of the stable well testing interpretation + transient well test interpretation is proposed firstly.it solves the well testing interpretation problems to low permeability reservoirs in Jilin oil field,and opens the new well testing interpretation situation for low permeability reservoir in Jilin oilfield.
