摘要： The present document provides a screening apparatus having a stack of screens (31,36,46) for retaining within a recycled drilling mud fluid, some solids within a particular size range. This fraction of solids is frequently referred to as lost circulation material or bridging material. Solids above a specified size can be removed with the top screen (31) and rejected, while solids of a smaller size but greater than a second size, can be separated with the second screen (36) and subsequently returned to the drilling fluid mud system, with solids smaller than those removed by the second screen but larger than a third size, may be removed with a third screen (46) and rejected. In other cases it may be desirable to return only the largest size particle fraction separated out at the first screen (31), for return to the drilling fluid where this is used in formations with particularly large pore size.

摘要翻译：本文件提供了一种筛分设备，其具有用于保持再循环的钻井泥浆流体的特定尺寸范围内的一些固体的一叠筛网（31,36,46）。这部分固体通常被称为堵漏材料或桥接材料。高于指定尺寸的固体可以用顶部筛网（31）去除并且被拒绝，而尺寸较小但大于第二尺寸的固体可以与第二筛网（36）分离并且随后返回到钻井泥浆系统，其中固体小于第二个筛网去除但大于第三个大小的固体可以用第三个筛网（46）去除并且被拒绝。在其他情况下，可能希望仅返回在第一筛（31）处分离出的最大粒径部分，以返回到钻井液中，其中这用于具有特别大孔径的地层中。

摘要： The present document provides a screening apparatus having a stack of screens (31,36,46) for retaining within a recycled drilling mud fluid, some solids within a particular size range. Additionally, the apparatus comprises a distributor which is formed and arranged so as to be switchable between a plurality of different flow directing configurations.
Said plurality of flow directing configurations include an intensive screening configuration in which the whole of the feed is directed onto a primary upper screen assembly (31) and the whole of the filtrate from said primary upper screen assembly (31) is directed onto a first screen assembly (36) and the whole of the filtrate from said first screen assembly (36) is directed onto a second screen assembly (46) and a parallel screening configuration in which the feed is passed through the primary upper screen assembly (31) and the filtrate from said primary upper screen assembly (31) is passed in parallel, through a respective one of the second and third screen assemblies (36,46).

摘要： The present invention provides a vibratory screening apparatus for use in removing solids from a liquid feed, and a basket therefor. The apparatus comprises a static outer housing, and a floating basket vibratable by a vibrator device, The basket mounts a stack of screen assemblies provided with respective flow directing trays for receiving filtrates from the screen assemblies. A flow distributor divides the feed into at least first and a second feed streams and directs them onto respective screen assemblies, and receives from the flow directing trays, filtrates from respective screen assemblies.

摘要： A method of manufacturing a filtering screen includes: attaching handle members (3) to edges of at least one wire cloth (1); providing a jig comprising tensioning means (23); placing the at least one wire cloth (1) in the jig and engaging the handle members (3) with handle member engagement portions (15) of the tensioning means (23). The tensioning means (23) are operated to drive the handle members (3) outwardly to tension the wire cloth (1) in orthogonal directions. The method also includes pressing the tensioned wire cloth (1) against a screen frame (6); bonding the wire cloth (1) to the screen frame (6); and trimming the wire cloth.
