shielding factor 中文意思是什麼
-
The in - house system evaluation and field application showed that an excellent oil film for shielding temporary plugging could be formed near borehole wall and both plugging and recovering rates of permeability reached more than 90 % when the added amount of the broad spectrum oil film temporary plugging agent gpj reached 3 % ; skin factor decreased by 7. 4 to 10 times and production increased by 1. 82 to 2. 96 times compared with conventional technology
結果表明，當廣譜「油膜」暫堵劑gpj的加量達到3 %時，可在近井壁處形成很好的屏蔽暫堵「油膜」帶，滲透率堵塞率和恢復率皆大於90 % ，與常規屏蔽暫堵技術相比，可使油層損害程度降低7 . 4 ~ 10倍，產量提高1 . 82 ~ 2 . 96倍，而且與油層滲透率和溫度無關。 -
It is shown that, by adopting supermirror guides with m = 2 instead of 58ni or natural ni guides, the transmission efficiency could be increased by the factor of 1. 3 ~ 1. 7, and the length of direct sight of the curved guides could be shorten greatly, which is useful for arranging shielding
研究表明，採用m = 2的超鏡導管較~ （ 58 ） ni導管或ni導管可以提高傳輸效率1 . 3 2 . 7倍，並使彎導管的直視長度變短，利於防護屏蔽安排。
