摘 要: 多解性是数值试井应用待解决的难题之一。相对解析试井,数值试井有更多可供调节的参数,多解性强。UST数值试井软件首次用相控建模约束地层的非均质性、用多井的实测压力数据约束解释结果,大大降低了数值试井的多解性,并且提高解释结果的准确性。在论述多井试井解释方法的技术要点的同时,给出了该解释方法的应用实例。 Multiple solution is one of the problems in the application of the numerical well test.Compared to the analytical well test,numerical well test has more parameters to adjust to fit the pressure data.UST numerical test firstly use face-controlled modeling to constraint the heterogeneity,and use the pressure data of multi wells to constraint the interpretation results of the well test analysis,which decrease the multiple solution of the numerical well test and make the interpretation results more precise.This paper introduces the technical points and gives a application.
