Project _Landslide_ will pursue a world-leading innovation for global drilling operations as employed in oil, gas, and geothermal. Such operations involve the drilling well bore holes, the hole is then lined with a tubular steel casing. The casing needs to be centralised within the bore and fixed in position by pumping cement into the void between the casing and the hole walls. An essential requirement is to assure the casing is kept central to the bore hole during this operation, and this job is done by "casing centralizers"- a cage-like steel apparatus that keeps the casing from touching the sides of the bore-hole. This gives the drilling team a complete 360-degree space around the casing for applying cement. The drilling industry uses two kinds of centralizers:**The bow-spring centralizer** **.** Slightly larger than the borehole, the spring mechanism holds the casing in place by applying pressure against the sides of the wellbore. They are often used in vertical wells as less deviance in annular space about the drill.**The rigid blade Centalizers**. These have no give and are more commonly used in deviated or horizontal well bores where weight of the casing would cause a bow spring centralizer to crush. Casing centralization ensures complete cement flow around the casing. Without this, gas/fluid migration can severely compromise well integrity leading to costly downtime due to necessary rework or worse, be life threatening & impart severe long lasting environmental damage as observed in Gulf of Mexico Deep Water Horizon disaster. Additionally to keeping casings away from the bore-hole in the high-pressure environment, centralizers are expected to assist in quicker run-in hole of casing. However, centralizers typically made from steel offer significant frictional resistance against the casing run-in hole. Various paint--on low-friction coatings and other engineering solutions have been tried, but wear off almost immediately or provide no advantage. Project _Landslide_ will explore an entirely new and untried concept of utilising solid low-friction linings ( similar to the technology used in car braking pads) to provide a controlled friction surface that is tough, with excellent compressive strength but also able to cope with the high temperatures and immense shear forces. _Landslide_ will unite a world-leading maker of centralizers, with leading experts from the brake and friction industry to transfer technology to create a new set of low-friction products offering clear cost, performance, safety, and environmental advantages in a highly competitive £500M global market

_landslide项目将在石油，天然气和地热中进行全球领先的创新。这样的操作涉及钻孔孔孔，然后将孔衬有管状钢壳。套管需要集中在孔内，并通过将水泥泵入壳体壁和孔壁之间的空隙来固定。一个必不可少的要求是确保在此操作期间套管保持孔洞的核心，并且该作业是通过“套管中心化”来完成的，这是一种笼子状的钢制设备，可防止套管接触孔洞的侧面。这为钻井团队提供了一个完整的360度空间，可用于施加水泥。钻井行业使用两种中心化机构：**弓箭中心器** **。**。它们通常在垂直井中用作环形空间中关于钻头的偏差。这些没有给予，并且更常用于偏离或水平井的孔中，因为壳体的重量会导致弓弹簧中心粉碎。套管集中化可确保围绕套管的完全水泥流。没有此，气体/流体迁移会严重损害良好的完整性，导致由于必要的返工或更糟糕的是，威胁生命并造成严重持久的环境损害，如墨西哥湾深水地平线灾难所观察到的严重持久的环境破坏。除了在高压环境中远离孔孔外，预计中央位置还有助于更快的壳体孔。但是，通常由钢制成的中心化可以对套管磨合孔具有明显的摩擦阻力。已经尝试了各种彩绘涂料和其他工程解决方案，但几乎立即磨损或没有任何优势。 Project _landSlide_将探索一个全新的，未经尝试的概念，即利用坚固的低摩擦衬里（类似于汽车制动垫中使用的技术），以提供较硬的受控摩擦表面，具有出色的抗压强度，但也能够应对高温和巨大的剪切力。 _ landslide _将团结一个世界领先的中心化制造商，来自制动器和摩擦行业的领先专家转移技术，以创建一套新的低摩擦产品，在5亿英镑的全球市场中提供明显的成本，性能，安全性，安全性，安全性，安全性和环境优势
