    Abstract: A filter includes a cylindrical filter element having a longitudinal axis, first and second end surfaces, and a plurality of longitudinal pleats. Each of the pleats has a pair of legs with first and second surfaces. The pleats are in a laid-over state in which the first surface of each leg is in intimate contact with the first surface of an adjoining leg and the second surface of each leg is in intimate contact with the second surface of an adjoining leg over substantially the entire height of each leg and over a continuous region extending for at least approximately 50% of the axial length of the filter element. An impervious end cap is connected to the first end surface of the filter element.

    Abstract: A filter is provided which combines a woven wire mesh over a supporting body. The supporting body is typically a metal perforated tube which provides fluid communication between the well bore and the production equipment string. The woven wire mesh acts as a filter to prevent the influx of sand particles, provides openings oriented at various angles relative to its surface, so that some area is available for fluid entry even when particulate matter is lodged on the surface above an opening, provides interior channels that allow fluid to travel from one location on the mesh surface to another location over an opening into the supporting body, and does not provide "straight-through" openings, thus forcing the fluid to make multiple turns to pass through the mesh, thereby dissipating the fluid's energy and increases the mesh's erosion resistance. When particulate matter accumulates on the mesh's surface, the resulting particle cake remains porous, heightening the filter's resistance to plugging.

    Abstract translation: 提供了一种将支撑体上的编织丝网组合的过滤器。 支撑体通常是金属穿孔管，其在井眼和生产设备串之间提供流体连通。 编织丝网用作过滤器以防止砂粒流入，提供相对于其表面以各种角度定向的开口，使得即使当颗粒物质沉积在开口上方的表面上时，一些区域也可用于流体进入，提供 内部通道允许流体从网格表面上的一个位置移动到穿过支撑体的开口上方的另一位置，并且不提供“直通”开口，从而迫使流体进行多圈以通过网状物， 从而消散流体的能量并增加网的抗侵蚀性。 当颗粒物质堆积在网状物的表面上时，所得的颗粒块保持多孔性，从而提高过滤器的堵塞性。

    Abstract: A coreless filter cartridge, and apparatus for adapting a filter housing to support such coreless filter cartridges. A coreless filter cartridge has an elongate array of filtering material which defines an interior cavity. The array is surrounded by a sheath of perforated paper. The ends of the array and sheath are embedded into polyurethane end-caps. The filter housing is adapted to accept coreless filter cartridges by adding a rigid, perforated standpipe that uses a bushing to fit over a housing fluid egress spud. The coreless filter cartridge is placed over the standpipe and secured in place by a retaining spider or by the housing cover, which exerts bias via a compression spring and compression cup. Gaskets on each end-cap prevent fluid by-pass and a stand-off cup is located near the base of the standpipe to provide a surface against which the end-cap gasket can seat.

    Abstract: Improved well screen has its open area defined by a helically wrapped strip of wire mesh which is supported by a rigid cage-like structure of welded steel longitudinal support rods and helical wrap wires. The design is cost competitive with the simple, and rather fragile, screens made by wrapping a mesh about a perforated pipe while offering the mechanical strength characteristics of wire-wrapped welded screens and a substantially larger open area for flow. The wire mesh strip is helically wound with a gap and at least one wrap wire is helically wound in the gap so that a small portion of its width can be firmly adhered to the rods while at least another portion of its width overlies an adjacent side edge of the mesh strip.
