摘要
建立了均质、上下封闭水平无限大油藏中水平井的试井模型，提出了用最小二乘法实现水平井试井分析的自动拟合方法．运用改进的ＬｅｖｅｎｂｅｒｇＭａｒｑｕａｒｄｔ回归方法，使自动拟合方法收敛速度更快．并用实例说明了该方法的实用性．
This paper presents a welltest model for horizontal wells bounded by two horizontal boundary planes at the top and the bottom. Both the top and the bottom boundaries are impermeable(no flow condition). By the use of the least square regression algorithm,we perform automatic type curve matching for well test analysis in horizontal well.Modified Levenberg Marquardt regression scheme makes automatic type curve matching more efficient. Actual field data are analyzed to illustrate the applicability of the method.
