顺托1井是中国石化西北油气分公司的一口重点外围探井,设计井深达到8 310m。由于重叠段环空间隙较小,决定采用内嵌卡瓦悬挂器进行尾管固井,但目前国内没有相应尺寸的尾管悬挂器。 Shuntuo 1 well is a key peripheral exploration well of Sinopec Northwestern Oil and Gas Branch, with a designed well depth of 8 310m. Due to the smaller annular gap in the overlapping section, the decision to use the inlay slipper suspension pipe for cementing of the tail pipe has been completed. At present, there is no corresponding tail pipe hanger in China.
