Desander for a downhole assembly
View Patent ↗A desander for a downhole assembly according to one disclosed non-limiting embodiment of the present disclosure includes a body that defines an axis; a support within the body; a sand downpipe within the body that extends from a sand downpipe inlet to a sand downpipe exit displaced from the sand downpipe inlet, the sand downpipe mounted to the support; and a solid-free intake to receive solid-free fluid from an upper body chamber.
1. A desander for a downhole assembly comprising:
a body that defines an axis;
a support within the body;
a multiple of sand downpipes within the body that each extend from a sand downpipe inlet to a respective sand downpipe exit displaced from the sand downpipe inlet, the multiple of sand downpipes parallel to the axis; and
a solid-free intake to receive solid-free fluid from an upper body chamber.
2. The desander as recited in claim 1 , wherein the solid-free intake is connected to a dip tube.
3. The desander as recited in claim 1 , wherein the sand downpipe is parallel to the axis.
4. The desander as recited in claim 1 , wherein the desander is connected to a gas separator.
5. The desander as recited in claim 1 , wherein the multiple of sand downpipes surround the solid-free intake within the support.
6. The desander as recited in claim 1 , further comprising a sand collector below the sand downpipe exit with respect to the support.
7. The desander as recited in claim 6 , wherein the sand collector is frustoconical in shape.
8. A method of removing sand from a fluid stream for a downhole assembly, comprising:
receiving solid-laden fluid through a multiple of sand downpipes parallel to an axis along a solid-free intake toward a bottom section discharge area separated by a vertical distance from the solid-free intake; and
receiving solid-free fluid from an upper body chamber through the solid-free intake.
9. The method as recited in claim 8 , wherein the multiple of sand downpipes are mounted in a support with the solid-free intake.
10. The method as recited in claim 8 , wherein the heavier sand particles from the multiple of sand downpipes drop to a sand collector at the bottom section of a desander.
11. The method as recited in claim 8 , wherein the solid-free intake is connected via a dip tube to a pump seating nipple or other pump intake section of the downhole assembly.
12. The method as recited in claim 8 , wherein receiving the solid-laden fluid through the multiple of sand downpipes comprises receiving the solid-laden fluid without helix separation.
13. The method as recited in claim 8 , wherein receiving the solid-laden fluid through the multiple of sand downpipes comprises receiving the solid-laden fluid without vortex separation.
14. The method as recited in claim 8 , wherein the multiple of sand downpipes are mounted in a support with the solid-free intake within a body, a length and a volume of a body related to a fluid production rate.
