摘要： A downhole flow control configuration including a housing, a converging-diverging flow path in the housing. The flow path includes a first portion including an inlet, a converging section, and a throat section. The first portion preferentially passes a portion of a fluid having a greater subcool. The converging-diverging flow path further includes a second portion comprising a diverging section that recovers fluid pressure lost in the converging section and the throat section, and an outlet and an elongated helical flow path connected to the outlet of the converging-diverging flow path, the helical flow path producing a pressure drop in a fluid flowing therein during use.

摘要： A flow control device including a housing having a flow port therein, the flow port including a first end and a second end, a first gate having a specific gravity greater than water disposed in the housing adjacent a first end of the port and movable between a position of nonobstruction of the first end of the port and a position of obstruction of the first end of the port; and a second gate disposed in the housing, the second gate having a specific gravity about the same as a specific gravity of formation water in a formation in which the device is intended to be employed, the second gate disposed to control flow at the second end of the port.
