改进的IIk反褶积算法在变流量试井中的应用
Application of improved Hk deconvolution method in variable flow well test
摘要
Abstract
Through introducing the five order NUAT B-spline deconvoluton scheme defined in a mixed algebraic and trigonometric polynomial space, an improved deconvolution algorithm was established based on Ilk model. The results show that the new algorithm not only inherits the stability advantage of Ilk algorithm, but also strengthens the curvature adaptation of Ilk deconvolution. Compared with the existent variable (low well test algorithms, the new algorithm has high accuracy and adaptability to common well test data. More amount and more accurate strata information can be obtained, and the stack effect can be eliminated using this method. And it also has good adaptability to well test data with complex pressure derivative curve.关键词
