Abstract

The utility model relates to a multi-stage rotary start type oil, gas and sand separator, and is an improvement and innovation on petroleum machinery and downhole oil, gas and sand separation tool devices. Two one-way gas exhaust valves and three spiral type separation channels are arranged in a sleeve pipe to carry out oil and gas separation. Two sand-proof nets and an oil permeating pipe are used for separating oil and sand, and thus the purpose on highly purifying crude oil is obtained. The utility model has the advantages of advanced structure, reliable performance, firmness, durability, etc. The utility model is an ideal downhole auxiliary oil production tool device.

Description

Multistage swing type oil gas sand separator
Technical field:
The present invention relates to petroleum industry, the improvement and the innovation of mechanical oil recovery down-hole aid equipment " gas and sand anchor ".
Background technology:
Because the crude oil in the oil well contains gas and sand grains, gas can reduce the oil yield of pump, influences output, waste kinetic energy; The sand card) or plucking and sand grains harm is bigger, can cause that oil well pump is stuck (to be commonly called as:, damage pump barrel and plunger and (be commonly called as: scuffing of cylinder bore), shorten the life-span of oil recovery machiner.Therefore, people also by increasing downhole tool equipment, promote oil, gas, sand separation except that managing to strengthen the abrasion resistance properties of oil well pump, to reduce the harm of gas and sand.The gas anchor and the sand anchor of independent use are arranged at present, the gas and sand anchor that unites two into one is also arranged.Wherein state-of-the-art gas anchor generally has one-level straight tube split tunnel and the spiral split tunnel of one-level to combine; Thick, the thin two-stage ductwork type desanding mode of the general employing of state-of-the-art sand anchor.And existing gas and sand anchor structure is all fairly simple, up to the present, does not find to adopt simultaneously the like product of above spiral Oil-gas Separation passage of two-stage and two-stage ductwork type desanding mode as yet.
Summary of the invention:
The objective of the invention is to: will have the gas and oil separating plant and the two-stage ductwork type oil-sand separator of 2 one-way exhaust valves, the spiral split tunnel of three joints to combine, and produce a kind of new product with superpower separating oil, gas, sand ability.
The present invention adopts following scheme to realize: in the long sleeve pipe of a radical rice, its top is gas and oil separating plant, and its underpart is the oil-sand separator.Gas and oil separating plant by dibit in the one-way exhaust valve A of top and the spiral split tunnel B that matches, by joint and save below spiral split tunnel C between oil pipe and the sleeve pipe combine; The oil-sand separator is formed by combining by the lower semisection and the floral disc of Oil Guide awl, two layers of sand control screens, saturating oil pipe, oil pipe with holes; Sleeve pipe upper end and one-way exhaust valve upper valve body, lower end and the seam of base cone joint constitute an integral body.
Description of drawings:
Describe solution of the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 is the full section schematic diagram of dibit in the gas and oil separating plant of the present invention in the one-way exhaust valve of top and the spiral split tunnel that matches.
Fig. 2 for a joint in the gas and oil separating plant of the present invention below spiral split tunnel between oil pipe and the sleeve pipe and the half section schematic diagram of oil-sand separator.
The present invention is the plastic products except that two balls 2, and all the other component are metal material.Now be described below successively: two one-way exhaust valve A, be made up of with ball 2 and valve seat 3 cylinder shape valve 1 and 6.Valve seat 3 is threaded with valve body 1 or 6 usefulness, and ball 2 usefulness polytetrafluoroethylmaterial materials are made, and under the effect of gas, can move up and down in valve body 1 and 6; Valve body 1 and 6 all bores an inclined hole in the position at ball 2 places, is used for the gas in the blow off valve.One taper pipe thread is arranged at the top of valve body 1, external oil well pump or its oil pipe; Use straight pipe thread in the bottom, connect oil pipe 4; Taper is processed in the outside, and dilated diameter is connected with sleeve pipe 5; On its conical surface, be drilled with several steam vents, be used for discharging the gas between oil pipe and the sleeve pipe 5.The supporting spiral split tunnel B of two joints is made up of oil pipe 4, central row tracheae 7 and spiral guide plate 8.Spiral guide plate 8 is welded in the outside of the central row tracheae 7 that is covered with pore, be enclosed within oil pipe 4 in; Two oil pipe 4 two ends are connected with upper valve body 1, following valve body 6 and joint 9 by screw thread, and the lower end of two central row tracheaes 7 is connected with joint 9 with following valve body 6 respectively with screw thread.Single step helical formula split tunnel C, by the part pipeline section of sleeve pipe 5, the upper semisection of oil pipe 11 with holes and spiral guide plate with holes 12 are formed.The upper semisection atresia of oil pipe 11 with holes is welded with spiral guide plate 12 with holes, and the top is connected with joint 9 with screw thread, and with nut 10 assemblies tightly, and the lower semisection oil permeable hole that gathers is as the part of oil-sand separator.The oil-sand separator is made up of the lower semisection and the floral disc 17 of Oil Guide awl 13, outer sand control screens 14, saturating oil pipe 15, interior sand control screens 16, oil pipe with holes 11.Oil Guide awl 13 be welded in oil pipe 11 with holes and spiral guide plate with holes 12 below, interior sand control screens 16 is rolled in oil pipe 11 lower semisections with holes, fixes with steel wire or screw gasket; Saturating oil pipe 15 two ends are connected with floral disc 17 with Oil Guide awl 13 respectively with screw thread; Outer sand control screens 14 is rolled in the outside of oil pipe 15, fixes with steel wire or screw gasket.The middle and upper part of sleeve pipe 5 many fuel feed holes that gather, two ends respectively with the bottom and the 18 top seam of base cone joint of upper valve body 1, constitute an integral body, be taper pipe thread below the base cone joint 18, use and store sandpipe or unidirectional sand flash valve is connected.
The specific embodiment:
During work, when the annular space that crude oil enters oil pipe 4 and sleeve pipe 5 from the middle and upper part fuel feed hole of sleeve pipe 5 trickles, carry out simple Oil-gas Separation downwards, gas gently rises, and oil heavily sinks.When entering the spiral split tunnel C of first segment, produce centrifugal force, fluid presses to the outward flange of spiral guide plate 12 with holes and the inwall of sleeve pipe 5, and gas is detained the inner edge of spiral guide plate 12 with holes, and passes the hole and upwards assemble, and is discharged by the steam vent on valve body 1 conical surface.Rotation and in the following fluid, sand sinks along sleeve pipe 5 inwalls because of than the great periphery that is in, through 18 discharges of base cone joint.Oil is in inner ring because of light specific gravity, draw in the suction of oil well pump under the effect of power and gravity, pass outer sand control screens 14, saturating oil pipe 15 and interior sand control screens 16, enter in the oil pipe 11 with holes, and move upward, through joint 9, enter the spiral split tunnel B of two joints of top successively, oil gas is separated once more under the effect of spiral guide plate 8, and oil rises along the inwall of oil pipe 4, and gas passes stack 7 risings in the air inlet edge, accumulate in the valve seat 3, when reaching certain pressure, just open baton round 2 automatically, discharge by outlet valve.Finally, clean fluid enters oil well pump through cylinder shape valve 1, outside the output well.
