Abstract:
A sand control screen comprising:a base pipe; anda screen wire having a general cross-sectional shape comprising a first substantially linear segment, a second substantially liner segment that is shorter than and substantially parallel to the first segment, a third segment extending between one end of the first segment and one end of the second segment, the third segment having a substantially convex arcuate shape and a fourth segment extending between the other end of the first segment and the other end of the second segment, the fourth segment having a substantially concave arcuate shape, the screen wire wrapped around the base pipe forming turns which extend along at least part of the length of the base pipe such that the third segment of the screen wire of one turn is adjacent to the fourth segment of the screen wire of the next turn, thereby forming gaps that reduce the velocity of particles traveling therethrough.
