Abstract
A novel underground three-phase separator is a solid, liquid, gas three-phase separating device arranged below a pump in oil-water well of oil field, which dissolves the shortcoming of the prior art and is formed by the connection of an upper joint, an external pipe for sand protection pipe, a living cutting sail sand protection pipe, an air exhaust pipe, an external pipe, an air exhaust valve, a nylon valve ball, a liquid outlet screen liner, a gas-collecting hood, an upper spiral external pipe, an upper spiral blade, a liquid inlet joint, a lower spiral external pipe, a lower spiral blade, a liquid inlet screen liner and a lower joint. The utility model has the following significances that the first point is that ''solid, liquid, gas'' three-phase separation has good effect; the second point is that a vibration screen is not easy to be blocked to improve effectiveness; the third point is that the service life of an oil well pump is extended.
Description
One, technical field: the utility model relates to a kind of " solid, liquid, gas " three-phase separating device that is installed in the oilfield oil well under the pump, especially a kind of novel down-hole three phase separator.
Two, background technology: the eliminator in the oil well is mainly by gas anchor and sand anchor at present, and gas anchor and sand anchor can not make up as a whole preferably, owing to there is not independently sand setting passage, has sand grains to be inhaled into once more after feasible the separation, and separating effect is bad.
Three, summary of the invention: the purpose of this utility model provide " Gu; liquid; gas " a kind of novel down-hole three phase separator of three phase separation, it has solved the deficiency of present technology, the purpose of this utility model is to realize like this, it is by top connection, anti-sandpipe outer tube, live and cut the anti-sandpipe of paulin, stack, outer tube, outlet valve, the nylon valve ball, the fluid screen casing, gas skirt, last spiral outer tube, last helical blade, the inlet joint, following spiral outer tube, following helical blade, the feed liquor screen casing, lower contact is formed by connecting, top connection and anti-sandpipe outer tube are by being threaded, live and to cut the anti-sandpipe of paulin and top connection, insert and prevent in the sandpipe outer tube by being threaded; Anti-sandpipe outer tube and outer tube joint be by being threaded, and outer tube joint and outer tube are by being threaded; Be welded with two stacks on the outer tube joint, the other end and the outlet valve of stack are welded to connect, and the nylon valve ball is housed in the outlet valve, and outlet valve and gas skirt be by being threaded, and outlet valve and fluid screen casing are by being threaded; The middle part of outer tube has three slotted eyes, is welded to connect at slotted eye place and inlet joint, and last spiral outer tube and inlet joint are by being threaded, and the last spiral outer tube other end cooperates with the fluid screen casing, and last helical blade is installed in the spiral outer tube; Inlet joint lower end and following spiral outer tube be by being threaded, following helical blade and the welding of feed liquor screen casing, and feed liquor screen casing one end welds with the inlet joint, and the lower end of outer tube and lower contact are by being threaded.
Operating principle: this novel down-hole three phase separator is installed under the oil well pump, under the swabbing action of oil well pump, liquid is entered by the inlet opening at middle part, along down helical blade is descending, liquid in rotation under the helical blade effect, the big sand grains of quality is under action of centrifugal force, the edge is the descending tail pipe that sinks to of screw thread outer tube wall down, liquid that quality is little and gas are descending along the feed liquor screen casing, and it is interior up to enter pipe by the feed liquor screen casing, enters in the helical blade of top; In the spiral outer tube of top, the material that quality is big is up in the action of centrifugal force lower edge spiral outside, enters in the pump through the fluid screen casing, less sand grains sinks in the tail pipe by the sand setting passage simultaneously, the gas that quality is little is up along the spiral inboard, enters outlet valve through gas skirt, is discharged by stack.
Meaning of the present utility model: the one, " solid, liquid, gas " three phase separation is effective; The 2nd, vibrosieve is difficult for being blocked, and has improved effect; The 3rd, prolonged application life of oil well pump.
Four, description of drawings: Fig. 1 is the front view of a kind of novel down-hole three phase separator, among the figure 1, top connection 2, anti-sandpipe outer tube 3, live cut the anti-sandpipe 4 of paulin, stack 5, outer tube 6, outlet valve 7, nylon valve ball 8, fluid screen casing 9, gas skirt 10, go up spiral outer tube 11, go up helical blade 12, inlet joint 13, spiral outer tube 14, spiral leaf 15, feed liquor screen casing 16, lower contact down down
