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

滑坡项目将在石油、天然气和地热领域的全球钻探作业中追求世界领先的创新。这种操作涉及到钻井井眼，然后在井眼内衬上管状钢制套管。通过将水泥泵入套管和井壁之间的空隙中，套管需要在井筒内居中并固定到位。一个基本的要求是确保在这次作业中，套管保持在井眼的中心，这项工作是由“套管扶正器”完成的，这是一种笼形的钢制装置，可以防止套管接触到井眼的两侧。这使得钻井队在套管周围有一个完整的360度空间来应用水泥。钻井行业使用两种扶正器：**弓形弹簧扶正器*。**略大于井眼，弹簧机构通过对井筒侧面施加压力来将套管固定在适当的位置。它们通常用于直井，因为钻头周围的环形空间内的偏差较小。**刚性叶片离心器**。在斜井或水平井中，套管的重量会导致弓形弹簧扶正器被压碎，这种情况下更常用。套管对中确保了水泥在套管周围完全流动。如果没有这一点，气体/流体的流动可能会严重损害油井的完整性，导致因必要的返工而导致代价高昂的停机时间，或者更糟，危及生命&造成严重的、长期的环境破坏，如墨西哥湾深水地平线灾难所观察到的那样。此外，在高压环境中，为了使套管远离井眼，扶正器有望帮助套管更快地进入井眼。然而，通常由钢制成的扶正器对套管下入井提供了显著的摩擦阻力。已经尝试了各种低摩擦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。项目_滑坡_将探索一种全新的、未经尝试的概念，即利用实心低摩擦衬片(类似于汽车刹车片中使用的技术)来提供坚韧的受控摩擦表面，具有出色的压缩强度，但也能够应对高温和巨大的剪切力。将联合世界领先的扶正器制造商和制动和摩擦行业的顶尖专家，转让技术，创造一套新的低摩擦产品，在竞争激烈的GB 500M全球市场上提供明显的成本、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
