| Abstract:In recent years, as the most important means of drilling into the ground, the formation is becoming more and more complex, and the probability of drilling collapse, falling blocks, reducing diameter, and over-diameter accidents is increasing, which seriously restricts the improvement of drilling engineering quality and efficiency. Wall protection and plugging material is an indispensable key engineering material in drilling engineering, and wall protection and plugging technology is an important technical link to ensure safe, fast, and continuous drilling work, and is the main content of drilling treatment in complex formations. From the perspective of science popularization, this paper introduces the basic concept and composition of wall blocking materials, the wall blocking effect of flushing fluid, the wall blocking effect of cement-based materials, and the further development space of wall blocking materials, so as to deepen the understanding of wall blocking materials and promote the research and development and application of new wall blocking materials. |
