| 摘 要： | 针对现有固井冲洗液评价方法对于油基钻井液冲洗情况评价存在不足的问题，运用环空壁面与改进装置内筒壁面处剪切速率相等的原理，研究出了一种适用于油基和水基钻井液条件的固井冲洗液室内评价新方法。室内模拟实验分析表明，该方法能更好地反映冲洗液的冲洗效率，并能模拟评价冲洗效率对固井第一或第二界面处胶结的影响情况。该方法操作方便，适用于油基和水基钻井液固井条件。

| Abstract: | The existing evaluation method of flushing fluid has some problems in evaluating the oil-base drilling fluid. This paper presents a new indoor evaluation method which would be suitable for evaluating both oil-based and water-based drilling fluids by using the principle of equal shear rate between annular wall and inner cylinder wall of improved device. Many indoor simulation experiments have demonstrated that this method can reflect flushing efficiency better; and by this method, the simulation evaluation can be made on influence of flushing efficiency to cementing conditions in the first or second bonding interface. This method has the advantage of convenient operation and is suitable for both water-based and oil-based drilling fluid cementing conditions. |
