摘要
为解决高升油田蒸汽驱开发过程中非常规完井方式对蒸汽驱提高采注比的制约与影响的问题,提出了一套非常规177.8 mm套管完井改139.7 mm尾管完井方法,实现Φ70 mm抽油泵和Φ88.9 mm油管下入油层中下部,进行强排液,为蒸汽驱提高采注比提供了新的途径。
Unconventional well completion has restrained the production factor of stead flooding in Gaosheng oilfield. To solve this problem, 139.7 mm tail pipe is used for well completion to alternate unconventional 177 .8 mm casing completion. By this method, 070 mm oil well pump and 088.9 mm tubing are run into the mid - low interval of the reservoirs to drain fluid, thus providing a new way for improving production factor of steam flooding.
