  • a pipeline 11 is provided at surface for further transporting produced hydrocarbon fluid that flows through the production tubing 8 to surface.
  • a production packer 12 is arranged between the casing 4 and the production tubing 8 to isolate an annular space 14 between the casing 4 and the production tubing 8 from the lower wellbore section 7, the annular space being filled with brine. Fluid pressure in the annular space is controlled via a control line 18 at surface.
  • a valve device in the form of standing valve 20 is provided at the lower end of the production tubing 8. The standing valve 20 is a one-way valve allowing inflow of hydrocarbon fluid into the production tubing 8 and preventing outflow of hydrocarbon fluid from the production tubing 8.
  • a pumping assembly in the form of sucker rod pump 22 is provided for pumping hydrocarbon fluid from the lower wellbore section 7 via the production tubing 8 into the pipeline 11.
  • the sucker rod pump includes a beam 24 rotatably connected to a post 26 whereby one end of the beam 24 is connected to a drive system 28 via arm 30. The other end of the beam is provided with a horsehead 32.
  • a plunger 34 is suspended in the production tubing 8 on a rod 36 having a polished upper portion 38 passing through a stuffing box at the wellhead 10 and being connected to the horsehead 32.
  • the plunger 34 includes a one-way valve system 39 allowing fluid to pass in upward direction through the plunger 34 and preventing fluid to pass in downward direction through the plunger.
  • the drive system 28 is arranged to induce reciprocating angular rotations to the beam 24 so as to induce a reciprocating vertical movement to the rod 36 and plunger 34.
  • the standing valve 20 received in a landing nipple 40 connected to the lower end of the production tubing 8 by connector 41.
  • the standing valve 20 comprises a cylindrical housing 42 having a central bore 43 that forms a flow passage for produced hydrocarbon fluid flowing into the production tubing 8.
  • the housing 42 is sealed to the inner surface of the production tubing 8 by one or more annular seals (not shown).
  • a seat ring 44 is arranged in the central bore 43 of housing 42.
  • the seat ring 44 is axially movable a short distance in the central bore, and diaphragm springs 46 are arranged below the seat ring 44 to bias the seat ring 44 upwardly against an annular shoulder of the housing 42.
  • a ball 48 is positioned in the central bore 43 above the seat ring 44.
  • the ball is axially movable between an open position whereby the ball 48 is axially displaced from the seat ring 44 and a closed position whereby the ball 48 seats on the seat ring 44 so as to close the flow passage 43.
  • Side openings 50 are provided in the housing 42 for flow of produced hydrocarbon fluid from the central bore 43 into the production tubing 8.
  • a cylindrical guide post 52 having a central bore 54 is connected to the housing 42 at the upper end thereof.
  • a rod element is arranged in the central bore 54, having telescoping upper and lower rod sections 56a, 56b whereby the lower rod section 56b is arranged to slide in axial direction through the central bore 54.
  • Reference sign 57 indicates the upper surface of lower rod section 56b.
  • a compression 59 spring extends around the lower rod section 56b acting to bias the lower rod section 56b in downward direction against the ball 48 thereby biasing the ball 48 onto the seat ring 44.
  • the upper rod section 56a is connected to a lifting member 60 having keys 61 adapted to be received in a J-slot 61a provided at the lower end of the plunger 34 ( Fig. 3 ).
  • a tubular support member 62 extends around the guide post 52 in a manner allowing the support member 62 to slide in axial direction along the guide post.
  • the interior of the support member 62 is provided with a ring 64 extending around rod section 56a and positioned against an annular shoulder 66 at the upper end of the support member.
  • the annular shoulder 66 is adapted to support the plunger 34 when the latter falls on the support member 62.
  • the ring 64 has an internal diameter allowing the ring 64 to axially slide along rod section 56a whereby downward sliding of the ring 64 is limited by the upper surface 57 of rod section 56b.
  • a compression spring 68 extends between the housing 42 and the ring 64, acting to bias support member 62 in upward direction against the lifting member 60.
  • the drive system 28 of sucker rod pump 22 is operated to induce a reciprocating angular rotation to the beam 24 and horsehead 32 resulting in a vertical reciprocating movement of the rod 36 and plunger 34.
  • the plunger thereby pumps hydrocarbon fluid that has entered the lower wellbore section 7, through the production tubing 8 to surface and further through pipeline 11 to a production facility (not shown).
  • the ball 48 is pushed onto the seat ring 44 by the action of spring 59 that pushes rod section 56b in downward direction against the ball 48, and by the action of the hydrostatic fluid column above the ball 48.
  • the ball 48 closes the flow passage 43 during each downward stroke thereby preventing backflow of hydrocarbon fluid from the production tubing 8 into the lower wellbore section 7.
  • hydrocarbon fluid is drawn into the production tubing via the flow passage 43 whereby the ball moves a short distance upwardly away from the seat ring 44.
  • the plunger 34 is lowered onto the standing valve so that the keys 61 of lifting member 60 latch into the J-slot of the plunger, where after the standing valve 20 is pulled out of the landing nipple 40 and retrieved to surface ( Fig. 2 ).
  • the plunger 34 In the event that, due to an inadvertent situation, the plunger 34 together with the rod 36 or a portion thereof falls onto the standing valve 20, the plunger 34 lands on the annular shoulder 66 of the support member 62. Due to the weight of the fallen component(s), the support member 62 and the ring 64 move in downward direction whereby the ring 64 slides along the rod section 56a. Upon the ring 64 arriving at upper surface 57 of rod section 56b, the latter is pushed in downward direction by the ring 64 and the support member 62. Rod section 56b thereby pushes the ball 48 onto the seat ring 44 so that the flow passage 43 becomes closed. The diaphragm spring 46 act to mitigate the impact forces between the ball 48 and the seat ring 44 when the plunger 34 lands on the support member 62.
