降低泥浆通过渗透介质时的滤失量的一种特殊泥浆添加剂。
A group of mud additives specifically designed to lower the volume of filtrate that passes through a filter medium.
充填效率随携砂液中砾石浓度、滤失量及砾石直径的增加而降低。
The packing efficiency decreases with the increase of gravel concentration in injected liquid, fluid loss to formation and gravel size.
在提粘、提切的情况下，对滤失量影响较少，能较好地满足快速安全钻井的要求。
It has less effect on the filter loss in increasing viscosity and shear, thus meeting the demands of fast and safe drilling relatively well. 1.
酸蚀蚓孔滤失量与排量、酸液粘度、酸液浓度、注酸时间以及储层物性有密切关系。
The acid wormhole leak-off volume is concerned with the pumping rate, the acid viscosity, the acid concentration, acid injection time and the formation physical property.
实验结果表明，一次交联聚合物弱凝胶具有剪切稀释的流变特征，耐剪切，注入性好，滤失量低；
The experiment results showed that preformed weak gel had many characteristics such as shear dilute rheological characteristic, anti-shear, easy injection and low filtration;
提出了一种优化多级交替注入酸压每一级交替时间及阶段液量的新方法，优化的依据是整个裂缝的瞬时总滤失量。
In this paper, a new method to optimize both alternating time and dosage of each stage of multistage alternating injection is put forward for acid fracturing.
计算表明：考虑天然裂缝渗透率变化的滤失量要远远大于常规双重介质模型得到的滤失量，当净压力较高时，二者可相差10倍之多。
The calculation shows that, fracturing fluid leak-off considered variable permeability are greater than conventional fractured loss model, when net pressure is higher, the two has 10 times difference.
