Definitions

  • the invention relates to well screens used in the petrol-chemical industry for the extraction of oil, gas or water.
  • the invention relates to a means of controlling the inflow or outflow of fluid from such well screens.
  • the invention provides an inflow control device for a well screen comprising: a body having an internal bore, said body mountable in line with a base pipe of said well screen; a plurality of body apertures in a wall of said body, said apertures spaced longitudinally and circumferentially from each other, about said wall; a slide member in sliding engagement with an inner surface of said body, said slide member having a plurality of slide apertures; wherein the inflow control device is arranged to selectively and progressively increase the aperture area through the body through sliding the slide member, so as to align at least one of the body apertures with at least one of the slide apertures.
  • the invention provides a means for controlling inflow through the sliding of the slide member and the limiting the intake of suspended material through provision of a screen protecting said apertures.
  • the inflow control device may have an external diameter matching that of the base pipe so as to connect to said base pipe with a flush connection.
  • Said connection may be a welded connection or a threaded connection. This will assist in mounting a screen over the apertures by permitting the screen to extend beyond the connection between the inflow control device and the base pipe.
  • the slide member may include an engagement portion for engaging an interruption tool so as to facilitate the sliding of the slide for the desired aperture opening.
  • the slide may operate in a range defined by discreet positions. Each discreet position may open a predetermined percentage of the total aperture area. Accordingly, by engaging the slide member and sliding to a predetermined position, the operator will be assured of the desired percentage opening.
  • the slide member may include a limit switch, possibly on a peripheral edge of said slide.
  • a limit switch may be an engagement lug or interference fit lug or a spring loaded limit switch or other similar device sufficient to transmit a vibration, impulse or resistance through the interruption tool so as to indicate to the operator the slide has reached the desired position.
  • the position of the apertures may be such that the positions between which the slide moves may be equal distance.
  • the slide member may be a longitudinal slide for sliding parallel to an axis of the inflow control device.
  • the slide member may be a circumferential slide so as to slide about the longitudinal axis of the inflow control device.
  • the interface slide and body may be machined to a tolerance sufficient to prevent leakage along the interface. Thus, no additional gasket may be necessary in order to seal the unopened apertures.
  • FIGS. 1A and 1B are various views of an inflow control device according to one embodiment of the present invention.
  • FIGS. 2A and 2B are various views of an inflow control device according to a second embodiment of the present invention.
  • FIG. 3 is a schematic view of a flow path through the inflow control device according to a further embodiment of the present invention.
  • FIGS. 4A and 4B are nets of components of the inflow control device according to one embodiment of the present invention.
  • FIG. 5 is a sectional view of an inflow control device according to one embodiment of the present invention.
  • FIGS. 1A and 2A show inflow control devices 5 , 50 mounted to well screens 10 .
  • FIGS. 1B and 2B show detailed views of the inflow control devices with cut away sections showing the internal arrangement of components.
  • the inflow control devices 5 , 55 having a body 12 with body apertures 30 penetrating the walls of the body 12 .
  • a collar 45 to protect the apertures and strengthen the wall of the body 12 .
  • On an internal bore of the body 12 is a slide member 25 arranged to slide in order to align or misalign corresponding apertures within the slide, and thus open or close the apertures allowing or preventing the flow of liquid into the well screen.
  • the slide member 25 is a longitudinal slide arranged to slide parallel to the axis of the inflow control device.
  • FIGS. 1A and 2A show a screen 15 .
  • the screen is not shown covering the apertures, however in practice water will flow through the screen and through the apertures of the body 12 and the slide member 25 in order to reach the internal bore of the inflow control device.
  • FIG. 3 is a schematic view of the fluid path 70 as it travels through the screen 15 , collar 45 , body aperture 30 and slide aperture 35 .
  • the slide member On sliding 75 the slide member so as to misalign the respective apertures 30 , 35 , fluid flow is prevented and so preventing ingress into the well screen.
  • FIGS. 4A and 4B shows nets (a 2 dimensional layout of a 3 dimensional object) of the body 80 and the slide member 85 according to one embodiment of the present invention.
  • the body includes two arrays 90 A, B of body apertures which are spaced longitudinally along the body and circumferentially about the body. It will be appreciated that several arrays may be included so as to provide a greater aperture area for fluid flow through the wall of the body.
  • FIG. 4B shows the net for the slide member 85 having two aperture arrays 110 A, B. The two arrays within the slide member 85 correspond to the two arrays 90 A, B of the body 80 . Taking the first array 110 A of the slide member 85 , the apertures are arranged in three separate groups 95 , 100 , 105 .
  • the first group is a single aperture 95 which represents a first slide position for the slide member 85 and corresponds to matching the slide aperture with the body aperture 92 .
  • the second group 100 includes two apertures which when the slide member 85 is in second position, correspond to two body apertures 92 , 94 .
  • a third group of apertures 105 then correspond to all the body apertures 92 , 94 , 96 . Accordingly, in a first position the slide member 85 corresponds to a 33% of the total aperture area to permit the ingress of water into the well screen. The second position permits 67% and the third position is fully opened.
  • FIG. 5 shows an alternative arrangement 115 of the inflow control device.
  • a base pipe 125 has a screen 120 mounted to an external diameter as previously described.
  • a slide member 130 Within the bore of the body 125 is a slide member 130 , however the sliding of the slide member is in fact a rotation 135 .
  • the slide member 130 may be rotated to achieve the same control over the percentage opening of the apertures with the body apertures and slide apertures corresponding as the slide member 130 rotates through each position.
  • the operation of the inflow control device is not merely limited to a longitudinal slide but, also extends to a rotational sliding member 130 .
