摘　　要：多年以来,低渗透油田的压降资料录取非常困难,大量的测试资料因为测不到径向流动段,利用传统的试井软件不能进行有效评价,造成试井解释多解性。要取得合格的测试资料必须采用较长时间的关井测试,增加了大量的测试成本。为了解决这一难题,开发了IDSSL续流解释软件,该软件通过分析续流阶段的压力速率变化,实现储层的准确解释。开展"短试井",不需要测到径向流动段,测试时长大大缩短,而且解释结果准确可靠,非常适用于低渗透油田的压降试井分析。Over the years,it is very difficult to acquire the pressure drop data in low permeability oilfield,and because radial flow section can't be measured,lots of testing data can't effectively evaluated by using the traditional well test software which causes well test interpretation more solutions. To obtain the qualified test data,a long time shut- in test must be used,which increases a big testing cost. In order to solve this problem,IDSSL stream interpretation software has been cooperatively developed,which realizes the accurate interpretation of reservoir through the analysis of the stress rate of postproduction phase change. To carry out the'short' well testing,needn't detect the radial flow section,the test time is greatly shortened,and the interpretation results are accurate and reliable,that is very suitable for well test analysis of the pressure drop in low permeable oil fields.
