Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Optimierung der Förderleistung mehrerer, in einem Ölfeld eingesetzter Exzenterschneckenpumpen zur Gewinnung von Erdöl aus, mit unerwünschten Zusätzen, kontaminiertem Erdöl.The The invention relates to a device for optimizing the delivery rate several, in an oil field used eccentric screw pumps for the extraction of petroleum, with undesirable additives contaminated petroleum.
Auf Erdölfeldern kommen mitunter 40 und mehr Exzenterschneckenpumpen zum Einsatz. Zur effizienten Nutzung der Pumpen müssen deren Beschaffenheit bei nachlassender Fördermenge schnellstmöglich überprüft werden, da tagelanger Produktionsausfall hohe Verluste erzeugt.On oil fields sometimes 40 and more progressing cavity pumps are used. For the efficient use of the pumps must their nature at decreasing flow rate are checked as soon as possible, because days of lost production produces high losses.
Aufgabe der Erfindung ist es, den Funktionstest für die im Ölfeld plazierten Exzenterschneckenpumpen in möglichst kurzer Zeit durchzuführen.task The invention is the functional test for the eccentric screw pumps placed in the oil field in as possible to carry out a short time.
Die Lösung der Aufgabe erfolgt mit den Merkmalen des Anspruchs 1. Weitere erfindungsgemäße Ausführungen sind den Merkmalen der Unteransprüche zu entnehmen.The solution The object is achieved with the features of claim 1. Further embodiments of the invention are to be taken from the features of the subclaims.
Entsprechend der Erfindung wird die Prüfung der Exzenterschneckenpumpe direkt vor Ort im Ölfeld auf einem Prüfstand durchgeführt. Die hierbei gewonnenen Erkenntnisse führen entweder zum gesamten Austausch der Pumpe oder zur Reparatur, die aufgrund von Verschleiß beim Stator oder Rotor erforderlich wird. Möglicherweise muß die Rotor-/Statorkombination auch ausgetauscht werden, weil sie der geänderten Temperatur im Bohrloch nicht mehr standhält.Corresponding The invention is the test of Progressing cavity pump performed directly on site in the oil field on a test bench. The this knowledge leads either to the entire Replacing the pump or for repair due to wear on the stator or rotor is required. possibly must the Rotor / stator combination also be replaced because they are the amended Temperature in the borehole no longer withstands.
Erfindungsgemäß weist der vor Ort Prüfstand sämtliche Einrichtungen auf, die notwendig sind, damit die Exzenterschneckenpumpe unter unterschiedlichen Betriebsbedingungen getestet werden kann. Hinsichtlich des Pumpendrucks wird der Gegendruck durch Regelventile erzeugt.According to the invention the on-site test bench all Facilities that are necessary for the eccentric screw pump can be tested under different operating conditions. With regard to the pump pressure, the back pressure is controlled by control valves generated.
Vorzugsweise weist der Prüfstand eine Regeleinrichtung auf, bei der, der vom Rotor erzeugte Öldruck simuliert durch ein Regelventil, kontinuierlich gemessen wird.Preferably shows the test bench a control device in which simulates the oil pressure generated by the rotor through a control valve, is continuously measured.
In einer weiteren vorzugsweisen Ausgestaltung der Erfindung hat der Prüfstand einen Ölbehälter, der mit einer Heizung oder Kühlung versehen ist, durch die das Öl auf die Temperatur gebracht werden kann, die im Bohrloch vorherrscht.In another preferred embodiment of the invention has the test bench an oil container that with a heating or cooling is provided by which the oil can be brought to the temperature that prevails in the borehole.
Der Prüfstand weist in einer weiteren vorzugsweisen Ausgestaltung eine Einrichtung, bestehend aus einem Lauf- und Zugwagen auf, mit Hilfe derer der Rotor mit dem Stator zusammengefügt wird. Die Bewegungsabläufe der Lauf- und Zugwagen geschieht bevorzug über einen Getriebemotor der durch Antriebsriemen mit den Wagen in Verbindung steht.Of the test bench in a further preferred embodiment has a device, consisting of a run and train cars, with the help of which Rotor is joined with the stator. The movements the runway and towing vehicle happens Favor over a geared motor by drive belt with the car communicates.
Nach einer weiteren Ausgestaltung ist dem Ölbehälter ein Vorlaufbehälter vorgeschaltet. Das aus der Pumpe zurückfließende Öl wird hier durch ein Sieb geführt, vom Abrieb, der aus der Rotation des Rotors entsteht, befreit und in den Vorlaufbehälter rückgeführt.To In another embodiment, the oil container is preceded by a supply container. The oil flowing back from the pump is here passed through a sieve, From the abrasion, which arises from the rotation of the rotor, free and in the supply tank recycled.
Es ist außerdem bevorzugt den Antrieb für den Rotor sowohl im Rechts- als auch im Linkslauf zu betreiben, damit das Zusammenfügen bzw. das Trennen des Rotors mit dem Stator erleichtert werden kann.It is also prefers the drive for the To operate rotor both in the right and in the left rotation, so the joining together or the separation of the rotor can be facilitated with the stator.
Eine weitere Ausgestaltung der Erfindung liegt darin, daß die Grundfunktionen des Prüfstands nicht nur an einem stationären Bedienungstableau, sondern auch an einem mobilen Teil mit gegebenenfalls weniger Bedienungsfunktionen vorhanden sind. Damit kann die Prüfung der bis zu 30 m langen Pumpen besser gesteuert und überwacht werden.A Another embodiment of the invention is that the basic functions the test bench is not only at a stationary Control panel, but also on a mobile part with, if necessary fewer operating functions are available. This can be the test of be better controlled and monitored up to 30 m long pumps.
Vorzugsweise ist der Prüfstand mit zwei Speisepumpen versehen, die mit den Pumpenkammern in Verbindung stehen. Die Speisepumpe mit dem großen Fördervolumen wird zur schnellen Füllung des gesamten Volumens, das sich aus den einzelnen Pumpenkammern ergibt eingesetzt. Die Pumpe mit dem kleinen Fördervolumen pumpt die während und nach dem Prüfvorgang anfallende Leckage in den Ölbehälter zurück.Preferably is the test bench provided with two feed pumps, which communicate with the pump chambers stand. The feed pump with the large delivery volume becomes fast filling the total volume resulting from the individual pump chambers results used. The pump with the small pumping volume pumps during and after the test procedure accumulating leakage in the oil tank back.
Entsprechend einer weiteren vorzugsweisen Ausgestaltung besteht die Pumpe aus mehreren Rotor-/Statorstufen wobei mindestens am Ende einer Stufe ein Drucksensor sitzt. An jedem Drucksensor läßt sich messen, ob die einzelne Pumpenstufe den von ihr zu erbringenden Förderdruck erreicht. Sollte dies nicht der Fall sein, so läßt dies auf einen möglichen Verschleiß schließen, wodurch ein gezielter Austausch einer bestimmten Pumpenstufe möglich ist, ohne Austausch des gesamten Rotor-/Statorkomplexes. Um dies zu ermöglichen ist der Stator und/oder die elastische Statorauskleidung mehrteilig. Möglicherweise läßt sich der Statormantel in seinem Querschnitt erweitern und die Statorauskleidung in bestimmten Bereichen ersetzen.Corresponding a further preferred embodiment, the pump is made several rotor / stator stages at least at the end of a stage a pressure sensor sits. At each pressure sensor can be measured whether the individual Pump level reaches the delivery pressure to be provided by it. Should this not be the case, so lets to a possible Close wear, causing a targeted replacement of a specific pump stage is possible without replacement of the entire rotor / stator complex. In order to make this possible the stator and / or the elastic stator lining is multi-part. possibly let yourself expand the stator jacket in its cross section and the stator lining replace in certain areas.
Der Prüfstand wertet aufgrund seiner Ausstattung mit den entsprechenden Meßgeräten das Drehmoment an der Antriebswelle, den Volumenstrom am Pumpenausgang, die Temperatur des Öls, den Druck am Pumpenausgang und die Drehzahl der Antriebswelle und damit des Rotors aus. Alle vorgenannten Werte können anhand einer SPS (Selbstprogrammierte Steuerung) vor- oder eingegeben werden, um mögliche Grenzwerte festzulegen.Of the test bench evaluates the torque due to its equipment with the corresponding measuring devices at the drive shaft, the volume flow at the pump outlet, the temperature of the oil, the Pressure at the pump outlet and the speed of the drive shaft and thus of the rotor. All the above values can be calculated using a PLC (self-programmed Control) are entered or entered to set possible limits.
