DOWN-HOLE GAS AND SOLIDS SEPARATION SYSTEM AND METHOD

摘要

A gas and solids separation system is disclosed to separate gas and solids in a subterranean wellbore thereby preventing the gas and solids from interfering with down-hole equipment. The system includes shrouds and diverters that directs the gas away from the intake of the down-hole artificial lift equipment and also utilizes solids collection chambers and shields which separate and trap solids.

主权项

1. A separator system for use in a wellbore extending from a surface to a subterranean reservoir, the system comprising:
a casing disposed in the wellbore; a tubular string extending into the casing; a first solids collection annular sealing device disposed in the tubular string; and a first solids collection device disposed in the tubular string and connected to the first solids collection annular sealing device, the first solids collection device comprising:
a first inner tubular connected to the first solids collection annular sealing device, wherein the first inner tubular has one or more openings;a first solids collection annulus formed by the first inner tubular and the tubular string, wherein the first solids collection annular sealing device forms an annular seal between the tubular string and the first inner tubular; anda first cover disposed on an end of the first inner tubular opposite the first solids collection annular sealing device above the one or more openings in the first inner tubular, wherein the first cover is configured to redirect flow out of the one or more openings in the first inner tubular.
