摘　　要：岔15-332X井是为了解冀中凹陷岔河集油田岔15断块长期注水后的油层情况而设计的一口密闭取心井。密闭取心对钻井液的滤失性、防塌性、携砂性和防卡性提出了更高的要求。本文介绍了岔15-332X井各井段的钻井液配方及其维护处理措施,以及密闭取心段的钻井液工艺。现场应用表明,该井所用的钻井液配方及维护措施是合适的,它满足了密闭取心的要求。Sealing core drilling is commonly used to understand the reservoir conditions after long term of injection. Suitable drilling fluid used is very important to the success of sealing core drilling . Drilling fluid formulation and field maintenance for different hole sections in Chal5-332X are described. It proved that the drilling fluid used possesses the advantages of low fluid loss, good cutting transportation and anti-slough-ing property, coring in the well was a success.
