Definitions

  • the invention relates to a method for conveying multiphase mixtures, in particular hydrocarbons from a borehole, with a positive displacement pump, through which the multiphase mixture is pumped, and a separation device, in which a gas phase is separated from a liquid phase, and a pump system with a positive displacement pump for conveying Multi-phase mixtures with a suction line and a pressure chamber, the suction line opens in particular in a borehole.
  • Multi-phase pumps per se are known, for example from US Pat EP 0 699 276 A1 , to which reference is made in its entirety and the disclosure of which is incorporated into the application.
  • Typical for hydrocarbon production, such as crude oil and natural gas production are pressure reductions on the sun head to about 2 - 5 bar, lower head pressures are usually due to the volume expansion of the gas content and the resulting increase in construction costs less economical.
  • the US 4,718,486 A1 describes a pump system in which process water is passed via a plunger pump to a jet pump in a borehole.
  • a suction line of the pump is connected via separators, tanks, oil separators and water treatment plants to the well, a feed line connects the pressure chamber of the plunger pump to the high pressure side of the jet pump.
  • the present invention seeks to provide a method and a pump system, with the improves the removal of the multiphase mixture and at the same time the required construction cost for the pump system is limited.
  • this object is achieved in that on the pressure side a partial flow of liquid is diverted from the main flow and directed to the high pressure side of at least one jet pump, which is arranged as a delivery aid on the suction side of the positive displacement pump, or that a feed line to the pressure chamber of the positive displacement pump with the high pressure side at least one Jet pump connects and the jet pump is arranged on the inlet side in the conveying direction of the positive displacement pump.
  • the pressure fluid used to drive the jet pump circulates between the jet pump and the positive displacement pump, in particular designed as a multi-phase pump, without permanent contamination of the delivery mixture occurring.
  • the power supply of the jet pump is ensured without an external energy source, in particular a hydraulic energy source must be provided.
  • the jet pump By a suitable design of the jet pump can be achieved that the positive displacement pump with a moderate form, which is for example 2 bar, is fed, so that the discharge of the multi-phase mixture improves and the free gas volume is limited simultaneously. As a result, the construction cost of the positive displacement pump can be reduced, which reduces the overall cost.
  • a moderate form which is for example 2 bar
  • the jet pump is arranged in or at the borehole, as far as the multiphase mixture is conveyed from a hydrocarbon source to facilitate the suction of the hydrocarbons.
  • the jet pump is disposed within the suction line.
  • Multiphase mixtures are characterized by a high variability in their composition, which is a multi-substance mixture that can be present in several phases.
  • the composition can change from nearly 100% liquid phase to nearly 100% gas phase, with large amounts of solids also being present in a multiphase mixture.
  • a separation of gas phase and liquid phase is carried out in the positive displacement pump and the partial liquid flow is branched off to the jet pump from the separated liquid phase.
  • a liquid is used to operate the jet pump, which only has a small proportion of gas and corresponds to the liquid phase of the product promoted.
  • a change or contamination of the conveying product by the use of the branched partial liquid flow as an energy source for the jet pump thus does not take place, and the positive displacement pump is always supplied with a liquid content suction side, so that a sufficient lubrication, cooling and sealing of the positive displacement takes place.
  • a further development of the invention provides that a partial volume flow of the separated liquid phase is metered via a short circuit line to the suction side of the positive displacement pump, ie that the supply line does not take place exclusively via the jet pump but via a short circuit line preferably arranged inside the positive displacement pump housing, thereby increasing the risk reduce the dry running of the positive displacement pump.
  • a further development of the invention provides that, after the diversion of the partial liquid flow, it is passed through an additional separator for the separation of gas phase and liquid phase, if the separation within the positive displacement pump was not sufficient.
  • the additional separator ensures that a largely freed of the gas phase liquid phase of the jet pump is supplied as a hydraulic fluid and energy.
  • a pressure-increasing pump is provided between the positive-displacement pump and the jet pump, by means of which the delivery pressure is increased.
  • the pump system provides that a feed line connects the pressure chamber of the positive displacement pump with the high pressure side of at least one jet pump, wherein the jet pump is arranged on one side in the conveying direction of the positive displacement pump to feed the positive displacement pump with a moderate form.
  • a feed line connects the pressure chamber of the positive displacement pump with the high pressure side of at least one jet pump, wherein the jet pump is arranged on one side in the conveying direction of the positive displacement pump to feed the positive displacement pump with a moderate form.
  • From the pressure side of the positive displacement pump so a partial flow of liquid to the high pressure side of one or more jet pumps, which are used as conveying aids, passed, resulting in a particularly economical pressure increase suction side.
  • jet pumps are extremely simple and have no moving parts.
  • separating means for separating gas phase and liquid phase in the pressure space are formed within the displacement pump housing, whereby the gas phase of the multi-phase mixture is separated from the liquid phase and only the liquid phase is used to drive the jet pump.
  • an additional separator is provided in the feed line, from the additional separator a return line of the separated gas phase leads to the pressure line of the positive displacement pump, so that the gas phase can be removed together with the remaining product for further processing.
  • a booster pump is arranged so that the separated liquid phase has an increased energy content.
  • the positive displacement pump is designed as a screw pump, since screw pumps reliably promote multi-phase mixtures, in particular with a high proportion of abrasive substances and strongly changing gas fractions, and offer advantages in terms of availability.
  • the jet pump is arranged in or at the borehole at the end of the suction line, alternatively it is possible that the jet pump is arranged at a different location, for example in the suction line closer to the positive displacement pump or in a borehole from the suction line.
  • Core of the pump system is a positive displacement pump 1, which is provided as a multi-phase pump and advantageously designed as a screw pump.
  • a suction line 10 is arranged, which opens into a borehole 3.
  • a jet pump 2 is arranged, which is oriented so that the high pressure side of the jet pump 2 is directed in the direction of the suction side of the positive displacement pump 1 to pressurize the positive displacement pump 1 with a pre-pressure.
  • the jet pump 2 preferably designed as a jet pump, is fed via a partial liquid flow 13, which has been branched off from the positive displacement pump 1 on the pressure side. Via a feed line 7 of the partial liquid flow 13 of the high pressure side of the jet pump 2 is supplied.
  • the partial liquid stream 13 is branched off from a separated multiphase mixture, wherein a separation of the liquid phase and the gas phase takes place within the positive displacement pump.
  • a predetermined amount of liquid phase is diverted from the pressure side of the positive displacement pump 1, the remaining product is conveyed through a pressure line 11 for further processing.
  • an additional separator 4 is interposed, from which a return line 14 leads to the pressure line 11, wherein the unnecessary liquid phase or the additional separated gas phase of the pressure line 11 is supplied.
  • a booster pump 5 is provided in the feed line 7 to increase the energy level of the pressure fluid for the jet pump 2.
  • a short-circuit line 15 is provided, via which a partial flow from the separated liquid is supplied to the suction side of the positive displacement pump 1 in order to always ensure adequate cooling and lubrication.
  • the short-circuit line 15 may also be formed within the positive displacement pump housing.
  • a delivery aid By the circulation of a partial flow of liquid within the pump system, a delivery aid is provided, so that the positive displacement pump can better promote the multiphase mixture due to the existing form, the volume expansion of the gas content is limited and the resulting increase in construction costs is avoided.
  • the simple design of the jet pump without moving parts reduces the construction effort and avoids downtime due to repairs caused by the wear of mechanical components.
  • no external energy source is used as the pressure fluid, which is mixed with the product, which can be a hindrance in the subsequent processing of the product.
  • no separate pressure fluid available so that a constant applicability of the pump system is guaranteed.
  • a plurality of jet pumps 2 can be fed from a positive displacement pump 1.
