| 摘 要： | 本文根据地下裂缝的漏失特性,建立了地下裂缝漏失规律的数学模型,并导出了各种流体在裂缝中的流动挽律。根据流动规律可以定量分析和计算漏速或漏失量与压差、裂缝尺寸、钻井液流变性能等之间的关系,这时优选优配堵漏荆的性能,选择合理的堵漏方法,提高防漏堵漏的成功率具有重要的指导意义。

| Abstract: | According to the properties of lost circulation in the creviced formationthis paper presented a mathematical model of the lost circulation law, It isfrom this mathematical model that the flow Iaw of various fluids is derived.On the basis of the flow law, the relation between leakoff velocity or leak-off rate and pressure difference, crevice sizes and rheological properties ofdrilling fluids can be quantitatively analyzed and calculated,It is of greatguiding significance to optimizing the plugging materials of lost circulationand reasonable plugging methods, and to improving the lost circulationeffectively in the drilling process, |
