摘要

研制了油包水乳化钻井液的基本配方,评价了其抑制性,热稳定性,以及抗水侵污能力,抗钻屑侵污能力,抗水泥侵污能力。现场应用表明,该体系具有较强的抑制作用,能很好地稳定井壁,保护油气层。

Abstract

The paper develops the base compound of water-in-oil emulsion drilling fluid , evaluates its inhibition , thermal stability and its capacity of water cut-resistance , well cuttings cut-resistance and cement cut-resistance. Its application in wells in operation shows that the system has stronger inhibition. It can stabilize well bore better and protects reservoirs.
