Definitions

  • a method of processing a drilling fluid used in a process in which a window is milled in a side of a well, such that the drilling fluid has swarf particles entrained therein comprising passing the fluid into an apparatus comprising a perforated rotating drum such that the swarf particles are retained therein while the drilling fluids pass through the perforations.
  • the drum has an axis of rotation which is preferably inclined, so that the swarf falls out of the lower end of the drum.
  • the outer drum is in the form of a screen of woven wire or similar material.
  • the method comprises passing the fluid to apparatus which further comprises means for conveying a thin layer of liquid which has passed through the two drums, and further comprises means located adjacent to the thin layer of liquid for exerting a magnetic force on metallic particles entrained therein.
  • Figure 4 is an end view on arrow C of the apparatus shown in Figure 3, and also shows a knife blade 76 mounted in the apparatus to remove strands of swarf which protrude from the inner drum 52.
  • FIG. 6 shows, schematically, a drilling system, in which a well 120 is formed in an underground -8- formation 122.
  • the well has a casing in the form of a steel tube 124. With the well exhausted, a further well can be drilled through a window 126 in the casing, formed by a milling tool 128.
  • Drilling fluids are supplied to the milling tool from a supply 130 (again shown schematically), and the swarf from the milling operation is floated to the surface. To allow the drilling fluid to be reused, the swarf must be removed from the fluid, and so it is passed to apparatus 132 as described with reference to the earlier figures.

Abstract

Procédé d'élimination des limailles présentes dans des fluides de forage utilisé dans un processus dans lequel on perce une fenêtre dans le côté d'un puits. Dans ce procédé on utilise un appareil se présentant sous forme d'un tambour perforé rotatif, et de préférence sous forme de deux tambours perforés rotatifs qui se logent l'un dans l'autre. Cet appareil est également décrit.
