钻孔冲洗液漏失是钻进复杂地层时最常见的一种现象,也是至今还未能有效地解决的一个难题.为了提高堵漏效果,多年来国内外不少部门和学者提出过许多漏失层的分类方法和消除漏失的措施.然而由于这些方法存在某些缺点,不能完全反映漏失的客观规律,使用条件有一定局限性,故未能得到普遍的采用.因此根据能反映漏失客观规律的漏失层特性,更合理地解决它的分类问题,并在这个基础上确定相应的堵漏材料种
Drilling fluid loss is the most common phenomenon when drilling into complicated formations and is a problem that has not been effectively solved so far.In order to improve the plugging effect, many departments and scholars at home and abroad have put forward many missing layers However, due to some shortcomings of these methods, they can not fully reflect the objective law of the loss, and the conditions of use have some limitations and therefore can not be universally adopted. Therefore, according to the omission that can reflect the objective law of leakage Layer characteristics, more reasonable solution to its classification problems, and on this basis to determine the corresponding plugging material species
