Abstract

A downhole circulation apparatus 2 comprises at least one tubular body portion 4 defining a first through-flow passage 6 through which drilling fluid can pass along the drill string. A first sleeve 10 is slidably mounted in the tubular body portion 4 and is biased into a position in which the first port means 8 is closed by a biasing means such as a spring 12. Second port means 18 is formed through the tubular body portion 4 at a location below the first port means 8 in the drill string. The second port means 18 may comprise a plurality of second nozzles, wherein each of the second nozzles has a diameter greater than the diameter of each of the first nozzles of the first port means 8. Larger nozzles enable large particle size drilling fluid to be bypassed. A second sleeve 20 is slidably mounted inside the tubular body portion 4.
