CARB3 剛性封堵劑 Rigid Plugging Agent
簡介Introduction
CARB3剛性封堵劑是一款專為鉆井作業(yè)開發(fā)的高性能工程材料，采用高強(qiáng)度無機(jī)材料、特殊改性礦物及功能性添加劑復(fù)合而成。產(chǎn)品通過填充、嵌入地層孔隙與裂縫，快速形成致密封堵層，有效解決井壁坍塌、地層漏失等復(fù)雜問題，提升鉆井液的防漏堵漏性能，保障鉆井作業(yè)安全******推進(jìn)，適用于各類復(fù)雜地質(zhì)條件下的鉆井工程，如破碎地層、裂縫性儲層、易漏失地層等。
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.
性能及優(yōu)點(diǎn)Performance and advantages
l 推薦加量：1.0%~5.0%；
l ******封堵能力，多種粒徑級配的剛性顆粒，快速在井壁表面形成高強(qiáng)度、低滲透性的封堵層，有效阻止鉆井液漏失，降低漏失速率達(dá)90%以上；
l 高強(qiáng)度與穩(wěn)定性，選用高硬度無機(jī)材料作為主要成分，在井下高溫、高壓環(huán)境中不易變形或破碎，確保封堵層長期有效。
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.
