waterflood efficiency 中文意思是什麼
-
Based on the preferable comparability of lithology between homogeneous core used in lab lest and that in strongly water washing part of inspection wells, forming condition of displacement efficiency in strongly water washing part of pressure coring inspection wells in waterflooded area has been analyzed, and reasons for the difference of displacement efficiency between pressure coring and in - house waterflood test have been discussed
摘要基於室內實驗採用的均質巖心與檢查井強水洗段巖性物性較好的相似性，通過對水淹區密閉取心檢查井強水洗段驅油效率形成、室內水驅油模擬條件的分析，指出了密閉取心與室內水驅油實驗驅油效率差別的原因。 -
Besides, the natural core in - house long - term washing out experiment has proved that waterflood efficiency of pressure coring can reach as high as 80 % ~ 90 %
天然巖心室內長期水沖刷實驗證實了密閉取心的水驅油效率可達80 % ~ 90 % 。
