| 摘 要： | 针对现场固井在"大肚子"环空段封固质量较差的情况,本文研制了含有"大肚子"环空段的注水泥(液体)流动模拟实验装置。利用该装置,研究井径扩大率、流量、液体流变性能等对"大肚子"环空处的流速场的影响规律。得到了不同情况下(井径扩大率、流量、液体流变性能等变化)"大肚子"环空段不同位置径向截面的流速曲线变化情况,为研究"大肚子"环空段的顶替机理提供了一定的数据资料。

Experimental Study for Regulation of liquid flow in oversized annular |
| |
| Abstract: | Aimed at the bad bondquality in the oversized annular, a flowing simulation quipment is developed in this paper. By this equipment fluid velocity field is researched in the situation that the enlargement, flux, rheological are changing. The flowing rule has been achieved under the different enlargement, flux, rheological. By this research,some data is obtained for the reseach of mechanisms about displacement in the oversized annular. |
