摘要
钻井液密度是否合理是衡量钻井过程中井壁是否稳定的关键因素之一,本文系统介绍了利用测井资料和力学理论确定合理钻井液密度的方法。用该方法对新疆油田某区块一口井的钻井液密度进行了确定,并通过现场资料进行了验证。该方法和结论对于井壁力学稳定性、钻井设计和钻井施工具有重要指导意义。
A reasonable drilling fluid density is one of key factors on wellface stability. This paper introduces the method of definiting drilling fluid density by using logging information and mechanics theory. Drilling fluid density of one well on Xinjiang Oilfield is definited by the method. This method is proven through the field data. This method and the conclusion have important significance for stability of sidewell mechanics, drilling design and drilling operation.
