Opfindelsen vedrører et brøndpumpeanlæg omfattende en afgangsledning og en hydraulisk drevet borerørspumpe med et pumpestempel og med en fodventil til indføring af væske til en første cylinder, en kontraventil 5 ved pumpestemplet, der med en stempelstang er forbundet med et slavestempel i en anden cylinder, der er koaksial med den første cylinder, samt ved toppen en hydraulisk drivenhed med mindst ét drivstempel, hvis modstående sider står i ledningsforbindelse med hver sin side af sla-10 vestemplet.BACKGROUND OF THE INVENTION The present invention relates to a well pump system comprising a discharge line and a hydraulically driven drill pipe pump having a pump piston and with a foot valve for introducing liquid to a first cylinder, a check valve 5 at the pump piston connected to a piston rod by a slave piston in a second cylinder coaxial with the first cylinder, and at the top a hydraulic drive unit with at least one drive piston, the opposite sides of which are in conjunction with each side of the slab piston.
Fra AU patentskrift nr. 239 991 kendes et brøndpumpeanlæg af den i indledningen angivne art. I dette kendte anlæg er den hydrauliske drivenhed forbundet med den neddykkede borerørspumpe via to fra pumpens afgangs-15 ledning adskilte rørledninger, hvoraf den ene tjener til at løfte slavestemplet og den anden tjener til at føre slavestemplet tilbage til sin udgangsstilling eller bundstilling.From AU Patent Specification No. 239,991, a well pumping plant of the kind specified in the introduction is known. In this known system, the hydraulic drive unit is connected to the submerged drill pump via two tubes separate from the pump discharge line, one of which serves to lift the slave piston and the other serves to return the slave piston to its initial position or bottom position.
Brøndpumpeanlægget ifølge opfindelsen adskiller 20 sig fra det kendte anlæg ved, at der ved borerørspumpen umiddelbart nedstrøms for kontraventilen ved pumpestemplet er en åben passage mellem rummet i den første cylinder over pumpestemplet og rummet i den anden cylinder over slavestemplet, at der foroven i afgangsledningen er 25 en ventil, der er indrettet til at afspærre afgangsledningen og til at åbne for denne, når pumpestemplet løfter den pumpede væske op gennem ledningen, og at den hydrauliske drivenheds ene stempelside, der er ledningsforbundet med undersiden af slavestemplet tillige 30 er forbundet med ventilen i afgangsledningen til styring af ventilen, medens den anden stempelside er ledningsforbundet med afgangsledningen umiddelbart opstrøms for denne ventil.The well pump system according to the invention differs from the known system in that at the drill pipe pump immediately downstream of the check valve at the pump piston there is an open passage between the space in the first cylinder over the pump piston and the space in the second cylinder above the slave piston. a valve adapted to block and discharge the discharge line as the pump piston lifts the pumped fluid through the line, and the one piston side of the hydraulic drive connected to the underside of the slave piston is also connected to the valve in the discharge line for controlling the valve, while the second piston side is wired with the discharge line immediately upstream of this valve.
Herved opnås, at pumpens afgangsledning samtidig 35 fungerer som en forbindelsesledning mellem den hydrauliske drivenhed og den neddykkede pumpe. Dette har den 2This results in the pump discharge line 35 simultaneously acting as a connecting line between the hydraulic drive unit and the submerged pump. This has the 2nd

fordel, at det kun er nødvendigt at føre en enkelt hydraulisk rørledning mellem drivenheden og den neddykkede borerørspumpe, hvilket resulterer i en simplere installation og dermed i - lavere udgifter til etablering og 5 drift af anlægget. Pumpeanlægget virker ved, at driven-heden via den omtalte hydrauliske rørledning forøger trykket på den ene side af slavestemplet, hvorved pumpestemplet løftes, og dermed løfter den pumpede væske op gennem afgangsrøret til overfladen. Samtidig påvirker 10 trykket i trykledningen ventilen i pumpens afgangsrør til åbning. Efter at pumpeslaget er afsluttet, lukkes ventilen i toppen af afgangsrøret, og dette sættes under tryk fra drivenheden ved hjælp af et kort hjælpetrykrør.advantage that it is only necessary to conduct a single hydraulic pipeline between the drive unit and the submerged drill pipe pump, which results in a simpler installation and thus in - lower costs for installation and operation of the plant. The pumping system works by driving the drive via the said hydraulic pipeline to increase the pressure on one side of the slave piston, thereby lifting the pump piston and thus lifting the pumped liquid through the discharge pipe to the surface. At the same time, the pressure in the pressure line affects the valve in the pump discharge pipe for opening. After the pump stroke is completed, the valve is closed at the top of the discharge pipe and this is pressurized from the drive unit by means of a short auxiliary pressure pipe.
Trykket i afgangsrøret forplanter sig via den 15 ovenfor omtalte åbne passage til den anden side af slavestemplet og trykker dette tilbage til sin bundstilling, hvor det er klar til at indlede en ny pumpecyklus.The pressure in the discharge pipe propagates via the open passage mentioned above to the other side of the slave piston and pushes it back to its bottom position, where it is ready to start a new pump cycle.
Opfindelsen beskrives nærmere i det følgende under henvisning til tegningen, hvor 20 fig. 1 skematisk viser et tværsnit i et brøndpum- peanlæg ifølge opfindelsen, og med en hydraulisk drevet hydraulisk drivenhed for borerørspumpen, og fig. 2 et delsnit af et alternativt mekanisk arrangement for drift af den hydrauliske drivenhed.The invention will now be described in more detail with reference to the accompanying drawings, in which: FIG. 1 is a diagrammatic cross-sectional view of a well pump system according to the invention and with a hydraulically driven hydraulic drive unit for the drill pipe pump; and FIG. 2 is a partial section of an alternative mechanical arrangement for operating the hydraulic drive unit.
25 En hydraulisk drivenhed 1 ved toppen af borerø ret er indrettet til aktivering af en borerørspumpe 2 og omfatter to cylindre 3 og 4, der er understøttet i et trug 5, og som har stempler 6 og 7, der er forbundet med hinanden ved hjælp af en stang 8.A hydraulic drive unit 1 at the top of the drill pipe is adapted to actuate a drill pipe pump 2 and comprises two cylinders 3 and 4 supported in a trough 5 and having pistons 6 and 7 connected by means of each other. and rod 8.
30 I den i fig. 1 viste udførelsesform anvendes der en hydraulisk motor til at bevæge stangen 8 frem og tilbage, men som vist i fig. 2 kan der anvendes en krumtapmekanisme .In the embodiment of FIG. 1, a hydraulic motor is used to move the rod 8 back and forth, but as shown in FIG. 2, a crank mechanism can be used.
Som vist i fig. 1 er stangen 8 ved hjælp af en 35 mekanisk forbindelse 9 forbundet med en anden stang 10, der er parallel med den første stang 8, og denneAs shown in FIG. 1, the rod 8 is connected by a mechanical link 9 to a second rod 10 which is parallel to the first rod 8, and this

3 stang 10 forbinder et par stempler 11 og 12 i et hy-draulmotororgan 13, hvilke stempler er anbragt i cylindre 14 og 15, der er anbragt parallelt med det første par cylindre 3 og 4, 5 Stemplerne 11 og 12 drives ved hjælp af hy~ draulfluidum fra en passende beholdning 18 ved hjælp af en hydraulpumpe 19, der virker gennem en solenoide-ventil 20, der styres af et par mikroafbrydere 21 og 22, der er placeret således, at bevægelsesesretningen 10 vendes, når den mekaniske forbindelse 9 mellem de to stænger 8 og 10 når til den ene mikroafbryder, og at retningen igen vendes osv., når den mekaniske forbindelse når til den anden mikroafbryder, hvilket sikrer, at drivstemplerne 11 og 12 via stængerne 10 og 8 reci-15 procerer stemplerne 6 og 7.3 rod 10 connects a pair of pistons 11 and 12 in a hydraulic motor member 13, which pistons are arranged in cylinders 14 and 15 which are arranged parallel to the first pair of cylinders 3 and 4, 5. Draul fluid from a suitable holding 18 by means of a hydraulic pump 19 acting through a solenoid valve 20 controlled by a pair of microswitches 21 and 22 positioned so that the direction of movement 10 is reversed when the mechanical connection 9 between the two rods 8 and 10 reach one microswitch, and the direction is reversed, etc., when the mechanical connection reaches the other microswitch, which ensures that drive pistons 11 and 12 recycle pistons 6 and 7 via rods 10 and 8 .
Til undgåelse af hydraulslag er der indkoblet en mikroprocessor 23 til styring af ventilen 20.To avoid hydraulic stroke, a microprocessor 23 is provided for controlling the valve 20.
Den neddykkede pumpe 2 har en øvre cylinder 25 og en nedre cylinder 26, hvilke cylindre har samme volu-20 men som cylindrene 3 og 4.The submerged pump 2 has an upper cylinder 25 and a lower cylinder 26 which have the same volume 20 as the cylinders 3 and 4.
Cylinderen 25 har et slavestempel 27, medens den nedre cylinder 26 har et pumpestempel 28, hvilke stempler er indbyrdes forbundne ved hjælp af en hul stempelstang 30, der passerer gennem en central skille-25 væg 31 og har en pakning 32, og såvel det øvre slavestempel 27 som det nedre pumpestempel 28 har åbninger, og det nedre pumpestempel 28 har en kontraventil 33, der lukker åbningen i stemplet under dettes opadgående bevægelse.The cylinder 25 has a slave piston 27, while the lower cylinder 26 has a pump piston 28, which pistons are interconnected by means of a hollow piston rod 30 which passes through a central partition wall 31 and has a gasket 32, as well as the upper one. slave piston 27 as the lower pump piston 28 has openings, and the lower pump piston 28 has a check valve 33 which closes the opening in the piston during its upward movement.
30 En fodventil 34 muliggør væskestrøm gennem en åbning 35 ind i den nedre del af et rum 36 i cylinderen 26, medens porte 37 i den hule stempelstang 30 muliggør væskepassage gennem stangen 30 til et rum 38 over pumpestemplet 28 i cylinderen 26.A foot valve 34 enables fluid flow through an opening 35 into the lower portion of a compartment 36 of the cylinder 26, while ports 37 of the hollow piston rod 30 allow fluid passage through the rod 30 to a space 38 above the pump piston 28 of the cylinder 26.

4 bøsning 46 og cylinderen 25 i forbindelse med et rum 44 i cylinderen 25 under slavestemplet 27, medens borerørspumpen 2's afgangsledning 42 er forbundet med et kammer 48 .i cylinderen 25 over slavestemplet 5 27.4, the sleeve 46 and the cylinder 25 in connection with a space 44 in the cylinder 25 below the slave piston 27, while the discharge line 42 of the drill pipe pump 2 is connected to a chamber 48 in the cylinder 25 over the slave piston 5 27.
I afgangsledningen 42 er der en ventil 50, der er belastet til lukket stilling ved hjælp af en fjeder 51, men som løftes fra sit sæde 52 i et kammer 53 af trykket på et stempel 54 fra trykledningen 40, hvil-10 ket tryk virker gennem en grenledning 55.In the outlet conduit 42 there is a valve 50 which is loaded to the closed position by means of a spring 51, but which is lifted from its seat 52 in a chamber 53 by the pressure of a piston 54 from the pressure conduit 40, which pressure acts through a branch line 55.
Formålet med ventilen 50 er at åbne for udstrømning fra afgangsledningen 42 under den tid, hvor væske i trykledningen 40 løfter stemplerne 27 og 28, medens strømmen lukkes, når stemplerne 27 og 28 føres 15 tilbage efter et løfteslag.The purpose of the valve 50 is to allow for discharge from the outlet conduit 42 during the time when fluid in the pressure conduit 40 lifts pistons 27 and 28 while the flow is closed as pistons 27 and 28 are returned after a lift stroke.
Tilbageføringen af stemplerne 27 og 28 opnås ved udadgående bevægelse af stemplet 7 i cylinderen 4, hvorved afgangsledningen 42 sættes under tryk via en hjælpetrykledning 57, der forbinder cylinderen 4 20 med kammeret 53.The return of the pistons 27 and 28 is achieved by outward movement of the piston 7 in the cylinder 4, whereby the discharge line 42 is pressurized via an auxiliary pressure line 57 connecting the cylinder 4 20 to the chamber 53.
På tegningen viser de fuldt optrukne pile strømningsretningen under løfteslaget, i hvilket tilfælde ventilerne 50 og 34 er åbne, og ventilen 33 er lukket. De punkterede pile viser strømningsretningen ved 25 returslaget, når ventilerne 50 og 34 er lukkede, og ventilen 33 er åben.In the drawing, the fully drawn arrows show the direction of flow during the lift stroke, in which case the valves 50 and 34 are open and the valve 33 is closed. The dotted arrows show the direction of flow at the return stroke when valves 50 and 34 are closed and valve 33 is open.
Det bemærkes, at stemplet 27 også kunne være forsynet med en ventil, der kunne lukke, når der sættes returtryk på slaveenheden.It should be noted that the plunger 27 could also be provided with a valve that could close when return pressure was applied to the slave unit.
30 Den i fig. 2 viste drivenhed kan erstatte den hy drauliske motor 13 og omfatte en krumtap 60, der ved hjælp af an stang 61 er forbundet med et krydshoved 62, der kan glide på en styrestang 63, der er fastgjort til cylindrene 3a og 4a, hvilket krydshoved 62 er 35 fastgjort til stangen 8a, der forbinder stemplerne i cylindrene 3a og 4a.The embodiment of FIG. 2 can replace the hydraulic motor 13 and comprise a crank 60 connected by means of a rod 61 to a crosshead 62 which can slide on a guide rod 63 attached to the cylinders 3a and 4a, which crosshead 62 is attached to the rod 8a connecting the pistons in the cylinders 3a and 4a.
