1) front plug
前塞
2) pre-slug
前置段塞
1.
Effect of pre-slug of Polymer/Surfactant upon the recovery efficiency of ASP compound flooding;
聚合物及表面活性剂前置段塞对三元复合驱采收率影响
3) frontal slug
前缘段塞
1.
The research shows that the concentration and size of the polymer slug must be optimized, and continuous slug in the process of polymer flooding must be ensured; the additional frontal slug and postprotective slug before and after the polymer slug are unnecessary.
研究表明 ,在聚合物驱油过程中 ,重要的是优化聚合物段塞的浓度和段塞大小及保证聚合物段塞不发生中断 ,在聚合物段塞前后附加前缘段塞和后保护段塞是没有必要
4) Preoperative embolization

2.
Methods Preoperative embolization therapy with gelatin sponge and PVA particles was performed in 42 patients with skull base meningiomas,followed by resection 3-7 days after embolization.
目的回顾42例颅底脑膜瘤施行术前栓塞治疗效果。
3.
Conclusions Preoperative embolization of the meningiomas for which blood is supplied completely or dominantly by ECA can make bleeding decrease and enhance surgical safety and the rate of total resection of the tumors in the patients with intracranial giant meningiomas.
目的探讨完全以颈外动脉供血或以颈外动脉供血为主的巨大脑膜瘤术前栓塞治疗的临床效果。

补充资料:段塞驱油剂
分子式:
分子量:
CAS号:
性质:在三次采油过程中,使用化学方法,即注入表面活性剂-聚合物或碱性水和聚合物,以降低界面张力,从而降低束缚残余油的毛细管力,以及保持有利的水-油的流度比,达到有效地驱替集油带,提高采油的收率。为了节省加入的化学品,可将注入化学品和注水交替进行,这就称为段塞。所加入的化学品称为段塞驱油剂。
