非金属 (NM) 井下管比钢制管具有更长的使用寿命，同时消除了腐蚀问题并降低了总拥有成本。然而，要使它们成为现实，需要一个具有多学科技能和技术专长的严格生态系统。完整的论文讨论了此类管材开发面临的挑战，从学术界和研究机构开始，以补充专业知识和计算机计算能力，再到材料供应商和管道原型制造设施。
NM 管道还可以包括金属元素，其中 NM 层的混合系统被纳入承担特定作用的多层管道结构中，类似于海底柔性立管、跨接线和流线中的金属压力铠装层。另一个例子是带有玻璃纤维增强环氧树脂 (GRE) 的聚合物衬里钢制刚性管，或双层热塑性衬里增强管（图）。
Nonmetallic (NM) downhole tubulars offer a longer lifetime than their steel counterparts while eliminating corrosion concerns and lowering total cost of ownership. Making them a reality, however, requires a rigorous ecosystem with multidisciplinary skill sets and technology expertise. The complete paper discusses the challenges that face the development of such tubulars starting from academia and research institutes to complement expertise and computer computational power and moving through to material suppliers and manufacturing facilities for pipe prototyping.
NM pipes also can include metallic elements, where a hybrid system of NM layers is incorporated into multilayered pipe structures that assume specific roles, similar to a metallic pressure armor layer in subsea flexible risers, jumpers, and flowlines. Another example is polymer-lined steel rigid pipes with glass-fiber reinforced epoxy (GRE), or a dual-layer thermoplastic-lined reinforced pipe (Fig.
