| 摘 要： | 针对均质油藏球向渗流问题,在考虑井筒储集、井底定流量生产、3种外边界(无穷大、定压、封闭)情形下,建立了考虑二次梯度影响的不稳定渗流的试井分析模型；先对此模型作线性化处理,把求解非线性的模型变为求解该线性的偏微分方程的定解问题,对定解问题关于时间tD作Laplace变换得到线性的常微分的定解问题,求解此定解问题得到了线... |

| Abstract: | This article suggests a spherical seepage problem in the homogeneous reservoir,considering well bore storage,bottom hole fixed flow and the three types of outer boundary(infinite,constant pressure and closed) cases,an instability seepage model was established in well testing analysis with consideration of the quadratic gradient.First,model was linearized,obtained linear partial boundary value of second-order differential equation.Further by using Laplace to transform to the time tD to get the ordinary diffe... |
| Keywords: | similar structure homogeneous reservoir quadratic gradient term instability spherical flow |
