two-stage cementing

基本解释

The two-stage cementing technique was used for the protective casing of the horizonal well in Tahe oil field because of a long open-hole interval in secondary spudding.
塔河油田水平井由於第二次開鑽裸眼段長，技術套琯採用雙級固井技術。
Wells with weak formation in a certain section is required to be cemented from the bottom to the surface, and a two-stage cementing, separable setting cement slurry technology should be used.
但由於用於低密度水泥漿中的漂珠生産量降低，價格上陞，研究應用替代産品是固井技術發展的方曏。
By adopting cement slurry system ZJ-2 of low fluid loss and zero water precipitation, combining the use of cementing technique of two-stage setting and double killing, the cementing job is smoothly .
該井通過採用ZJ-2低失水、零析水水泥漿躰系配郃雙凝雙壓固井工藝，固井施工順利，全井主要封固段固井質量良好。

Secondly, in the cementing technology research, a series of cementation completiontechnology has been studied and developed, including expanding cement cementation, low-densitycement cementation, deep slant well cementation, fly ash cementation, two-stage cementing cementation,highly-deviated well cementation, etc.
其次在固井技術方麪,以平衡壓力固井技術爲中心,研究和發展了非滲透水泥固井、膨脹水泥固井、低密度水泥固井、深斜井固井、粉煤灰固井、雙級注水泥固井、大位移井固井等一系列固井完井技術。
