LANDSLIDE – Next Generation Well Bore-Hole Equipment for Geothermal, Oil & Gas Industries.

landslide_项目将追求世界领先的创新，用于全球石油、天然气和地热钻井作业。这种作业包括钻井，然后在井眼内衬钢管套管。套管需要在井眼内集中，并通过将水泥泵入套管和井壁之间的空隙中来固定位置。在作业过程中，一个基本要求是确保套管保持在井眼的中心位置，这项工作是通过“套管扶正器”来完成的，套管扶正器是一种笼状的钢制装置，可以防止套管接触井眼的侧面。这使得钻井队在套管周围有一个360度的空间，可以进行固井作业。钻井行业使用两种扶正器：**弓形弹簧扶正器** **。**弹簧装置比井眼略大，通过对井筒侧面施加压力来固定套管。它们通常用于直井，因为钻头周围的环空空间偏差较小。**刚性叶片扶正器**。这些扶正器没有弹性，通常用于斜井或水平井中，在这些井中，套管的重量会导致弓形弹簧扶正器被压碎。套管扶正确保了套管周围完整的水泥流动。如果不这样做，天然气/流体运移可能会严重损害井的完整性，导致由于必要的返工而导致昂贵的停机时间，甚至更糟，可能会危及生命，并造成严重的长期环境破坏，正如墨西哥湾深水地平线灾难所观察到的那样。除了在高压环境下使套管远离井眼外，扶正器还可以帮助套管更快下入井眼。然而，通常由钢制成的扶正器对套管下入孔具有显著的摩擦阻力。各种低摩擦涂层和其他工程解决方案已经尝试过，但几乎立即磨损或没有任何优势。项目_滑坡_将探索一个全新的和未经尝试的概念，利用固体低摩擦衬里（类似于汽车制动垫的技术）来提供一个可控的摩擦表面，该表面坚韧，具有优异的抗压强度，但也能够应对高温和巨大的剪切力。landslide_将联合世界领先的扶正器制造商，与来自制动和摩擦行业的领先专家转移技术，创造一套新的低摩擦产品，在竞争激烈的5亿英镑全球市场中提供明确的成本，性能，安全和环境优势

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
