MetalSkin®套管内补贴管系统优点
• Elastomer seal bands give more reliable zonal isolation than cement squeezes and don‘t significantly reduce well ID as do scab liners. 橡胶密封带提供比挤水泥更加可靠的封隔带，并会比下隔离尾管产生更小的缩径. • Large ID for the full length of the expandable system maximizes production and injection rates and provides better access for future intervention operations. 全膨胀段大内径最大化产率及注入率，并且为以后的修井作业提供更好的通路. • Simplistic work system increases operational reliability and without drill out procedure . 简单化作业系统增加作业可靠性，避免了作业后钻塞的工序. • Hydraulic jack protects casing and connectors because the expansion pressure is contained within the jack rather than subjecting tubulars to expansion pressure cycles. 液压千斤顶保护了套管和接头，因为膨胀压力在千斤顶内而不是把膨胀管作为压力腔.

MetalSkin®裸眼膨胀管系统优点
• Unique design maximizes running clearance to minimize effect on ECD and run time; helps avoid differential sticking. 独特的设计使转动间隙最大化，从而把对当量循环密度和下入时间的 影响减到最小；有助于避免差压卡钻. • Optimal-yield base pipe reduces expansion pressure requirements by 33 percent to reduce operational risk and maintain liner integrity. 最佳屈服值的膨胀管降低了33%的膨胀压力要求，从而降低了作业风 险以及维持了膨胀管的完整性. • Collapsible, retrievable expansion cone avoids becoming stuck by retracting for retrieval at any time. 可收缩可回收的膨胀锥避免了任何时候回收遇卡. • Metal-to-metal expandable connectors exceed proposed API standards in testing for burst, collapse, tensile and compressional resistance. 金属对金属可膨胀连接强度超过推荐的API标准，包括耐内压强度， 耐外压强度，抗拉强度和耐压缩强度.

MetalSkin®裸眼膨胀管系统优点(续)
• Hydraulically assisted expansion balances pressure across cone so a seal does not form on the cone face and forces tending to swage the cone are minimized; improves reliability and avoids risk of casing erosion. 液压辅助的膨胀平衡了锥横断面的压力，所以不会在锥面形成密封，使锥变形的力也减到 最小；从而提高了可靠性，避免了膨胀管的腐蚀风险。 • Hydraulic jack reduces risk of costly delays by serving as a backup system to resume expansion of casing in the event pressure is lost during expansion. 液压千斤顶作为膨胀时压力损失的情况下的备用系统来继续膨胀，从而降低了代价很高的 延误风险 • Primary pressure seal contains expansion pressure with greater consistency through use of a valve system rather than relying on darts to create and maintain system's pressure seal. 主压力密封包括了使用阀系统的一致性更好的膨胀压力，而不是依靠胶塞来建立和维持系 统压力密封 • Elastomer sealing elements reduce well construction costs and risks by providing zonal isolation without underreaming and cementing. 合成橡胶密封降低了建井造价以及无扩眼和注水泥的层位封隔风险
