| 摘 要： | 根据稠油的渗流特征，建立了邻井为注汽井考虑热损失的稠油热采有限多井试井模型。应用拉氏空间叠加方法，得到了压力在Laplace空间的解析解，利用Stehfest数值反演，绘制了样板曲线，并对样板曲线进行了敏感性分析。结果表明：考虑热损失时，油井受邻井的影响不明显；而不考虑热损失时，油田开发的中后期油井受邻井的影响将较为明显。

| Abstract: | A finite multi-well test model taking consideration of heat loss and with adjacent wells as steam injectors has been established based on seepage flow characteristics of heavy oil.A new pressure superposition method has been proposed when we are doing Laplace transformation,and the analytic solution of pressure is obtained.Type-curves are drawn by Stehfest numerical inversion and analyzed for sensitivity.The result indicates that the influence of adjacent wells on oil producers is not obvious when considering heat loss,while the influence of adjacent wells on oil producers would be obvious in the middle-late life of oilfield development without consideration of heat loss. |
