Definitions

  • the present invention relates to a method and a device for optimizing the transfer by pumping of effluents consisting of at least one gaseous phase and at least one liquid phase, in a transfer pipe between a source of effluents and a place of destination in adapting the flow rate of the pump used to the fluctuating conditions upstream and downstream of it.
  • fluids or effluents can come from various sources, in particular from wells drilled such as oil wells.
  • the essential function of the pump is to apply to the fluids or effluents admitted at its inlet with a certain intake pressure or suction pressure, a compression or increase in pressure sufficient to compensate for the pressure losses that they may suffer downstream. during their transfer.
  • upstream and downstream refer to the pump by considering the direction of flow of the effluents, and the term flow generally designates the volumetric flow.
  • the method according to the invention aims to optimize the transfer of effluents in a transfer pipe by means of a multiphase pump capable of pumping both liquid and gaseous phases by adapting its flow to fluctuating conditions upstream, such as the variation in the flow rate of the effluent source and the variation in the value of the volumetric ratio of the gas phase to the liquid phase, hereinafter abbreviated as GLR (Gaz Liquid Ratio) which is representative of the variation in the composition of the fluid during its transfer, and downstream such as the pressure drops appearing in the pipe.
  • GLR Gaz Liquid Ratio
  • the method can be applied to the transport of a multiphase fluid from a well to a place of destination such as a treatment terminal or an underwater or land treatment platform.

  • GLRa and Pa the variation in flow rate of the multiphase pump linked to the pressure losses downstream of the pump and to the variation in the volumetric ratio at the pump suction and at the suction pressure
  • the devices and methods currently employed for transporting multiphase type fluids by pipeline combine, in general, a pump adapted to discharge a multiphase fluid consisting of at least one liquid phase and one gaseous phase whose volumetric ratio varies within relatively narrow limits. .

  • the pumping devices known from the prior art are not designed to take into account the flow fluctuations of the wells as well as the pressure losses suffered during transfers. Also, the well flow is closely dependent on the flow rate of pumps used. The production capacities of wells can be significantly reduced.

  • the method is characterized in that the speed of rotation is regulated so as to adapt the flow rate of said multiphase pump to at least one of said variations and in that the speed of rotation of the pump is determined by a combination of values of four parameters which are the inlet pressure at the input of the multiphase pump, the volumetric ratio at the inlet of the pump (GLRa), the compression applied by the pump and the total flow rate of the effluents produced by said source.
  • the speed of rotation is regulated so as to adapt the flow rate of said multiphase pump to at least one of said variations and in that the speed of rotation of the pump is determined by a combination of values of four parameters which are the inlet pressure at the input of the multiphase pump, the volumetric ratio at the inlet of the pump (GLRa), the compression applied by the pump and the total flow rate of the effluents produced by said source.

  • Compression can be determined by an iterative process by adding to a previously determined value the successive variations of the discharge pressure.
  • the value of the effluent flow can be determined by an iterative process.
  • the method can be applied to the transfer of a multiphase petroleum effluent between a source of effluents, such as a well, and a place of reception of said effluent.
