Abstract
A device for sampling drill cuttings includes a frame, an inclined perforated member mounted on the frame, a sprayer for washing cuttings down over the perforations, and a removable open-topped cuttings collector mounted under the perforated member, the perforated member cooperating with the downstream end of a vibratory screen over which the cuttings pass before translating onto the perforated screen.
Claims (10)
1.A device for sampling drill cuttings comprising:
a frame mountable at, so as to cooperate with, a downstream end of a vibratory screen over which drill cuttings are passed in a downstream flow direction so that vibratory motion of the vibrating screen is transmitted at least in part to said frame, an inclined perforated planar member mounted on said frame, said planar member including a plate or sieve screen having perforations over at least a portion thereof between an upstream end and a downstream end of said planar member wherein said perforations are sized to screen out those cuttings exceeding a pre-determined size and to allow to pass through said perforations those cuttings equal to or less than said pre-determined size, and wherein said perforations are disposed on said planar member so that a substantially linear flow path between said upstream and downstream ends of said planar member along which cuttings translate pass over so as to intersect a plurality of said perforations, a sprayer mounted adjacent said upstream end of said planar member so as to direct fluid spray downstream along said planar member and over said perforations, an open-topped cuttings collector removably mounted under said frame so as to be insertable into a collecting position disposed beneath said perforations on said perforated planar member, and removable from said frame so that the cuttings may be removed from said collector for analysis, wherein said planar member is covered by adjustable cover plates so that only a pre-selected ratio of the cuttings on the vibratory screen are entrained onto the perforated portion of said planar member, whereby, the drill cuttings for any particular drill-hole cross-section are uniformly sampled and the resulting sample of a selectively pre-determined volume for ease of and efficient removal for analysis.
a frame mountable at, so as to cooperate with, a downstream end of a vibratory screen over which drill cuttings are passed in a downstream flow direction so that vibratory motion of the vibrating screen is transmitted at least in part to said frame, an inclined perforated planar member mounted on said frame, said planar member including a plate or sieve screen having perforations over at least a portion thereof between an upstream end and a downstream end of said planar member wherein said perforations are sized to screen out those cuttings exceeding a pre-determined size and to allow to pass through said perforations those cuttings equal to or less than said pre-determined size, and wherein said perforations are disposed on said planar member so that a substantially linear flow path between said upstream and downstream ends of said planar member along which cuttings translate pass over so as to intersect a plurality of said perforations, a sprayer mounted adjacent said upstream end of said planar member so as to direct fluid spray downstream along said planar member and over said perforations, an open-topped cuttings collector removably mounted under said frame so as to be insertable into a collecting position disposed beneath said perforations on said perforated planar member, and removable from said frame so that the cuttings may be removed from said collector for analysis, wherein said planar member is covered by adjustable cover plates so that only a pre-selected ratio of the cuttings on the vibratory screen are entrained onto the perforated portion of said planar member, whereby, the drill cuttings for any particular drill-hole cross-section are uniformly sampled and the resulting sample of a selectively pre-determined volume for ease of and efficient removal for analysis.
2. The device of claim 1 wherein said collector is a perforated container for straining fluid from the cuttings passing into said collector through said perforations in said planar member.
3. The device of claim 2 wherein said collector is a rigid walled container having a base comprising a mesh screen.
4. The device of claim 1 wherein said planar member is a plate, and wherein said plate is inclined in the range of substantially 10-30 degrees from the horizontal so as to elevate said upstream end of said planar member to cooperate with the downstream end of the vibratory screen when said frame is mounted adjacent the downstream end of the vibrating screen so that the cuttings translating in the flow direction flow from the vibrating screen onto said plate, and wherein said plate is inclined so that cuttings travel from said upstream end to said downstream end and subsequently off said downstream end, and wherein the device further comprises a hinged mount rotatably mounted to said frame for releasable mounting to the downstream end of the vibratory screen and adapted so as to selectively pivot said frame and said planar member relative to said vibratory screen.
5. The device of claim 4 wherein said planar member is inclined substantially 15 degrees.
6. The device of claim 1 wherein said frame defines a drawer support and wherein said collector is a perforated drawer for draining fluid from the cuttings while retaining the cuttings in the drawer, and wherein said drawer is selectively drawn out from under said planar member and selectively slid back into said frame so as to align an open top of said drawer under said perforations on said planar member.
7. The device of claim 1 wherein said collector is a first collector and removable from said frame so that a second, empty collector may be inserted into said frame in place of said first collector once said first collector has accumulated a sample of the drill cuttings passing through said perforations in said planar member.
8. The device of claim 6 wherein said drawer is entirely removable from said frame.
9. The device of claim 3 wherein said mesh screen of said base of said collector has a sieve screen mesh size which allows fluids and any particles smaller than said sieve screen mesh size to pass through said mesh screen, while retaining on said mesh screen cleaned cuttings larger than said sieve screen mesh size.
10. The device of claim 1 wherein said perforations on said planar member may be of uniform diameter or of different diameters.
