简介Introduction

CARB3刚性封堵剂是一款专为钻井作业开发的高性能工程材料，采用高强度无机材料、特殊改性矿物及功能性添加剂复合而成。产品通过填充、嵌入地层孔隙与裂缝，快速形成致密封堵层，有效解决井壁坍塌、地层漏失等复杂问题，提升钻井液的防漏堵漏性能，保障钻井作业安全******推进，适用于各类复杂地质条件下的钻井工程，如破碎地层、裂缝性储层、易漏失地层等。

CARB3 Rigid Plugging Agent is a high-performance engineering material specifically developed for drilling operations. It is composed of high-strength inorganic materials, specially modified minerals, and functional additives. The product fills and embeds into formation pores and fractures, rapidly forming a tight plugging layer. It effectively addresses complex issues such as wellbore collapse and formation fluid loss, enhancing the leak prevention and plugging performance of drilling fluids. This ensures the safe and efficient progress of drilling operations. CARB 3 is suitable for drilling projects under various complex geological conditions, including fractured formations, fractured reservoirs, and formations prone to fluid loss.

性能及优点Performance and advantages

l 推荐加量：1.0%~5.0%；

l ******封堵能力，多种粒径级配的刚性颗粒，快速在井壁表面形成高强度、低渗透性的封堵层，有效阻止钻井液漏失，降低漏失速率达90%以上；

l 高强度与稳定性，选用高硬度无机材料作为主要成分，在井下高温、高压环境中不易变形或破碎，确保封堵层长期有效。

l Recommended dosage: 1.0% to 5.0%;

l High-efficiency plugging capability: The rigid particles with a variety of particle size distributions quickly form a high-strength, low-permeability plugging layer on the wellbore surface, effectively preventing the loss of drilling fluid and reducing the leakage rate by over 90%;

l High strength and stability: High-hardness inorganic materials are used as the main components, which do not deform or break easily in the high-temperature and high-pressure downhole environment, ensuring the long-term effectiveness of the plugging layer.
