摘　　要：针对试井分析具有多解性,其解释结果的可靠性评价还没有专门的技术手段这一问题,采用压力分布分析来评价试井得到的解释结果,将解释结果中的数据,绘制成生产井和注水井(生产井)之间的井间压力分布图,并由此图来检验渗透率等其它参数的准确性。通过调整压力分布图来克服试井解释的多解情况。可以更准确的得到地层参数,判断试井解释的可靠性。Because of the multi- solution of well test analysis, and no special technique method of reliability evaluation of explaration bresult, pressure distribution analysis is used to evaluate the explaration result obtained form well test, the data from the explaration is dipicted into the inter-well pressure distribution map between producers and injectors, and furtherly,the map is employed to check the accuracy shch parameters as permeability and so on, the problem of well test esplaration multi- soluaiton is overcome through adajusting pressure distribution. The formation parameters can be obtained more precissily, the reliability of well test explaration can be daviced.
