Pump for viscous oil production

The rotary displacement pump RDCP5-10-1500 by Novomet-Perm has been already performing for 100 days in the Messoyakhaneftegas well.

It should be reminded that the first assembly of the submersible displacement pump was installed by Romanian company OMV Petrom in the well in June 2015 and since that moment it has been performing for two years and five months. On the 20 of February 2017 also in Romania there was put into service the second assembly of RDCP. Both assemblings are performing well.

In Romania there was used RDCP and it allowed to avoid the breakage of rods, but in conditions of Messoyakhskoe field, which is characterized by increased content of solid particles in the produced fluid, it is necessary to do periodic flushing for progressive cavity pumps that are performing there now, and it leads to loss of time and implication of an additional equipment. By comparison the assembly of a rotary displacement pump works non-stop and it doesn’t require any additional operations.

The innovative development of the company is based on the pump of absolutely new type – vane-type. Comparing to plunger-type and progressive cavity pumps, it doesn’t contain elastomeric materials, doesn’t have string of rods that means it shouldn’t take into account any characteristics of produced fluid, it doesn’t have limits about the produced pressure head, and it can be installed even in horizontal sections of the wells.

To date the assembly of RDCP5A-50 is ready for trial operations, which is the next step in developing of the production of rotary displacement pumps, that are intended to operate in the wells with viscous oil.

In conclusion it should be noted that there aren’t any foreign analogs of this equipment for today.
