井漏;循環液漏失
Newspapers might have lost circulation, but they haven\\'tlost their readership.
報刊的發行量可能下降了,但它們的讀者并沒有流失。
Lost circulation is often happened during drilling in multi -fracture formation.
井漏是多裂縫地層鑽井作業中經常發生的複雜情況之一。
When 0.3% - 0.5 % thixotropic regulator was added, the lost circulation material had good thixotropy.
觸變調節劑使堵漏劑具有良好的觸變性,其用量占主劑的0.3% - 0.5%較佳。
Therefore lost circulation has always been an urgent technical problem in the process of well drilling.
所以,井漏一直是鑽井工作中亟需解決的技術難題。
Mao east area frequently takes place sloughing hole, pipe-stuck, lost circulation in drilling operation.
鄚 東地區鑽井過程中經常發生垮塌、卡鑽、井漏等複雜事故。
lost circulation(井漏) 是指鑽井過程中,鑽井液(泥漿)從井眼環空非預期地大量漏失到地層中的現象。它是鑽井作業中常見且具有挑戰性的複雜情況之一。
