井漏;循环液漏失
Newspapers might have lost circulation, but they haven\\'tlost their readership.
报刊的发行量可能下降了,但它们的读者并没有流失。
Lost circulation is often happened during drilling in multi -fracture formation.
井漏是多裂缝地层钻井作业中经常发生的复杂情况之一。
When 0.3% - 0.5 % thixotropic regulator was added, the lost circulation material had good thixotropy.
触变调节剂使堵漏剂具有良好的触变性,其用量占主剂的0.3% - 0.5%较佳。
Therefore lost circulation has always been an urgent technical problem in the process of well drilling.
所以,井漏一直是钻井工作中亟需解决的技术难题。
Mao east area frequently takes place sloughing hole, pipe-stuck, lost circulation in drilling operation.
鄚 东地区钻井过程中经常发生垮塌、卡钻、井漏等复杂事故。
lost circulation(井漏) 是指钻井过程中,钻井液(泥浆)从井眼环空非预期地大量漏失到地层中的现象。它是钻井作业中常见且具有挑战性的复杂情况之一。
