High Gas Cut Well Downhole Pump

Date:2024-05-06 Popularity:737

RockySea Petro High Gas Cut Well Downhole Pump

  • RockySea Petro Petro, have specially designed sucker rod pumps for high gas cut wells to avoid these problems: Gas locking prevention oil well pump, long plunger anti-gas & anti-sand downhole pump, forcing valved open type insert pump, double-plunger valve type sucker rod pump, etc.
  • What is more serious? Operation with conventional sucker rod pump in high gas cut wells will result in liquid impact, which would accelerate the damage of tubing, sucker rod strings, pump valves, valve cages, and other downhole equipment.
  • In oil wells with high gas cut, the oil liquid has poor fullness. So if we adopt conventional sucker rod pumps for oil recovery, normally we will get a very low pump efficiency. Meanwhile, gas locking may happen frequently, which will bring a lot of trouble to oil recovery and make us lose countless time and money for repairing the downhole pumps.

  • Wear Resistance
    The plunger can rotate freely to prevent sand stuck and partial wear.
  • Anti Sand
    The patent anti sand and anti burying standing valve can prevent valve seat from being punctured.
  • Avoid Liquid Impact
    The unique design of the high gas cut well downhole pump can effectively prevent liquid impact.
  • Avoid Gas Locking
    The traveling valve is a spherical valve for forced opening and closing.

Liquid impact: 
During the upstroke, if the pump is not completely filled with well liquid, a low-pressure air cap will be formed on the top of the pump chamber between the floating valve cage and the fixed valve cage. During the subsequent downstroke, the gloating valve cage will keep closed until being hit by the well liquid surface. This phenomenon is called “liquid impact” and it will cause severe impact load on the entire artificial lifting system.

Gas locking: 
After frequent compression and expansion of the gas in the sucker rod pump, the suction valve often cannot be opened normally. So that the crude oil cannot be pumped out. This phenomenon is called “gas locking”.
