摘要： A method of manufacturing a selective isolation screen includes steps of preparing for a tubular screen (2) provided with spacer members (4) and a wire (5) on a base member (3), and supplying sealing material from a sealing material supply device (6) which supplies sealing material at a location where sealing is required on the tubular screen while rotating the sealing material supply device relative to the tubular screen thereby filling the annulus between the spacer members which are adjacent to each other in the circumferential deirection to form seal means (7). Difficulty in welding can thereby be avoided and location and state of mounting of sleeves can be visually checked.

摘要： A well liner (16) having a selective isolation screen with a limited or less restrictive seal. The well liner (16) includes an elongate base (2) pipe having openings (5) therethrough; surrounded by circumferentially spaced, longitudinal extending spacer bars (3) for forming an inner annulus (7); one or more annular cylindrical sleeves (4) secured to the exterior of the base pipe (2); and a continuous wire wrapping (6) surround the spacer bars (3) except at interrupted areas where the isolated permeable seal sections (10) are placed. The continuous wire wrapping (6) and spacer bars (3) are inverted within the permeable seal sections (10) so that the wire wrapping 6) subtantially fills the inner annulus (9) and a multitude of spacer bars spaced approximately equal to or slightly larger than the spaces between the wire wrapping form the outer most surface of the seal sections (10). The ends of the seal sections (10) are coupled to the wire wrapping (6) screen of the well liner for forming a continuous screen surface and seal.

摘要： A well screen for a horizontal or high-angle well includes a screen main body (11) and a protective frame (12). The screen main body has screen rods (14) arranged in the circumferential direction and a screen wire (15) wound on the screen rods. The protective frame includes protective rods (16) provided on the outside of the screen wire in the circumferential direction and extending in the axial direction of the well screen, annular rod holding members (17) provided with interval in the axial direction for holding the protective rods, and a protective wire (18) wound on the protective rods. When the well screen forced into the well passes through a bent section of the well, the protective frame slides in contact with the wall surface of the bent section thereby protecting the screen wire.

摘要： A multi-layer composite screen (1) having filters of a plurality of layers superposed one upon another is provided. Each filter (2, 3) of the plurality of layers has wires (4, 6) of a substantially triangular or trapezoidal cross section arranged in parallel to one another with a continuous slit (5, 7) of a substantially V-shaped cross section being formed between respective adjacent wires, said slit widening increasingly inwardly from the surface (4a) of the screen. The wires (4) of one filter (2) of the respective adjacent filters cross the wires (6) of the other filter (3) and the respective adjacent filters (2, 3) are fixed to each other at crossing points of the wires of the respective filters. In one aspect of the invention, the wires (6) of the lower layer are formed with linear projections (8) extending in the longitudinal direction of the wires which facilitate electrical welding of the filters of the adjacent layers.
