    摘要: Methods and apparatus to determine operating parameters of a pumping unit for use with wells are disclosed. An example apparatus includes a housing and a processor positioned in the housing. The processor is to determine a rate at which to operate a motor of a pumping unit to enable a load imparted on a polished rod of the pumping unit to be within a threshold of a reference load or to enable a speed of the polished rod to be within a threshold of a reference speed.

    摘要: Diagnosing a pump apparatus having a downhole pump disposed in a deviated wellbore characterizes axial and transverse displacement of a rod string with two coupled non-linear differential equations of fourth order, which include axial and transverse equations of motion. To solve the equations, derivatives are replaced with finite difference analogs. Initial axial displacement of the rod string is calculated by assuming there is no transverse displacement and solving the axial equation. Initial axial force is calculated using the initial axial displacement and assuming there is no transverse displacement. Initial transverse displacement is calculated using the initial axial force and the initial axial displacement. Axial force and friction force are calculated using the initial displacements, and the axial displacement at the downhole pump is calculated by solving the axial equation with the axial force and the friction force. Load at the downhole pump is calculated so a downhole card can be generated.

    摘要: Une pompe de puits comprend une étance à coches (2) supportant une poutre mobile (1) qui oscille pour agir sur un secteur de suspension (3) mettant en action une ou plusieurs tiges de commande de pistons d'aspiration dans un trou de puits. L'invention élimine le besoin de monter un volant, une boîte de vitesse ou autres moyens mécaniques connectés à la base pour provoquer ou commander le mouvement d'oscillation de la poutre mobile. Un chariot (5) supporte de manière mobile une masse d'équilibrage (4) sur la poutre mobile et est positionné par un cylindre hydraulique (6) ou autre moyen de positionnement pour changer la position relative de la masse d'équilibrage, provoquant ainsi l'oscillation de la poutre mobile. Un système de commande de la masse mobile (11-21) règle les moyens de positionnement et la fréquence de sa course de sorte qu'une grande plage de conditions variables de fonctionnement peut être utilisée. Un mode de réalisation comprend une poutre mobile (1') adaptée pour être reliée à ses extrémités à des tiges de commande de pistons d'aspiration (53a, 53b) dans différents trous de puits.

    摘要: Methods and apparatus to determine parameters of a pumping unit for use with wells are disclosed. An example apparatus includes a housing and a processor positioned in the housing. The processor is to determine a first load on a polished rod of a pumping unit, to estimate a first torque of a motor of the pumping unit, and determine a first torque factor for the pumping unit. The processor is to, based on the first load, the first torque, and the first torque factor, determine a phase angle of a counterbalance of the pumping unit or a moment of the counterbalance.

    摘要: An apparatus and method for pumping fluids with a winched rod pumping apparatus for imparting reciprocating substantially vertical motion to a rod of a sucker-rod pump. A winched rod pumping apparatus, includes a motor driven winch drum and cable mechanical actuator arrangement. The winch drum and cable mechanical actuator arrangement includes a substantially vertically moveable member attached to the rod of the sucker-rod pump. The vertical moveable member is coupled to one end of the cable and the other end of the cable is coupled to the winch drum. The winch drum is configured to rotate in one direction to index the rod in a vertical up direction and to index the rod in a vertical down direction, with the winch drum completing at least one full rotation and the rod completing one cycle. The rod cycle is in relation to a pumping cycle for the down hole pump.
