  • Patent number: 9915256
    Abstract: A well pump has a standing valve seat with a standing valve mounted in a lower end of a barrel. A plunger is carried within the barrel for axial stoking movement. A travelling seat with a travelling valve are mounted in a lower end of the plunger. The travelling valve has a head that lands on the travelling valve seat while the travelling valve is in a closed position. The travelling valve has a stem extending downward from the head through a hole in the travelling seat. The stem is a permanent magnet. Another permanent magnet is carried by the barrel below the travelling magnet. The polarities of the magnets are configured to interact and cause the travelling valve to lift relative to the travelling seat to an open position as the plunger nears a bottom of a stroke.

  • Patent number: 9880569
    Abstract: A predicted outflow rate (Qo) at which gas is discharged from a process chamber 2 via a vacuum pump 3 is computed, and an input flow rate (Qi) is calculated in order to reach a preset target pressure (Psp). The input flow rate (Qi) is calculated, on the basis of the expression Qi=Qo+(?P/?t)V, from a known volume (V) of the process chamber 2 and a pressure change rate (?P/?t) obtained from the current pressure (P1) within the process chamber 2 to reach the target pressure (Psp). A current predicted outflow rate (Qo) is estimated on the basis of the expression Qo(n)=P2*f1(P2), from the current pressure (P2) within the vacuum pump 3 and a known characteristic pumping rate (Sp=f1(P2)) of the vacuum pump 3 under preset pressure.

    Abstract: The present application includes and assembly having a dual dart assembly operable between an upper cage and a lower cage. The dual dart assembly is configured to connect an upper dart and a lower dart via a connecting rod. Therefore movement of one dart causes equal movement in the other dart. Movement of the dart is dampened upon impact at the top and bottom of the well by restriction of the working fluid as the dart assembly seats and unseats. A series of expandable seals are independently operated around the outer body and configured to expand and contact the outer wall in response to pressure increases within the outer body.

  • Patent number: 9850744
    Abstract: A method for extracting coalbed gas. A wellhead device delivers power fluid into a downhole power fluid pipe in a well shaft, and conveys the fluid to a pump in a pump cylinder connected with the downhole power fluid pipe. The pump sucks in formation fluid via a suction inlet, mixes the fluid with the power fluid to produce a mixed fluid, and conveys the mixed fluid to ground surface. The mixed fluid containing coal dust travels at a flow rate greater than a sedimentation rate of the coal dust, passes though the wellhead device, and flows to the ground surface, thereby preventing a sedimentation of the coal dust. The suction inlet of the pump reaches a lower boundary of a coalbed so as to prevent coal dust from burying the coalbed, and the coalbed gas automatically shoots through an annular space of a well shaft casing.

The drive unit has a piston (2) that is able to slide inside the vertical hydraulic cylinder (4) upon adding a drive fluid, where the piston rod (2) is the polished rod of the sucker rod string (1).

    Abstract: A well pump assembly includes rotary pump and a submersible motor. A shroud surrounds the pump intake and the motor. The shroud has an open upper end in fluid communication with the pump intake. A tubular member of smaller diameter is secured to and extends downward from a lower end of the shroud. The tubular member may have an open lower end for drawing well fluid along a lower flow path up the tubular member to the pump intake. An upper flow path at the upper end of the shroud may have a minimum flow area that is smaller than a minimum flow area of the lower flow path. The tubular member has a smaller outer diameter than an outer diameter of the shroud. The tubular member may have a closed lower end to define a debris collection chamber with a drain valve.

  • Patent number: 8955582
    Abstract: A beamless mechanic-reversing long stroke pumping unit is provided for petroleum production in diverse types of oil fields. Its mechanic-reversing system consists of differentials, brakes, etc. With two differentials assembled together, taper gears inside them perform revolution and rotation, enabling the pumping unit to achieve direction change and speed change mechanically. The stroke length of the pumping unit can reach 8 meters or longer, and the adjustment process is more convenient than most, by merely tuning the position of the proximity switches. Abrasion of the chains typically caused due to resetting of a motor frequently during operation, is eliminated in this pumping unit. The pumping unit has more reliable operation performance, more convenient maintenance, lower costs, better energy saving effects, and can be applied in land oil fields, offshore oil fields, oil wells with low permeability, etc.
