    • An apparatus and method for pumping fluids, such as water and/or hydrocarbons, from a subterranean formation or reservoir, include a linear rod pump having a mechanical rack and pinion drive arrangement, adapted for attachment to a pumping mechanism, such as the polished rod at the top of a rod string in a hydrocarbon well. The rack gear, of the rack and pinion drive arrangement, is adapted for connection to, and movement with, the polished rod. The pinion gear does not translate with the rack gear, and is driven by a reversible motor for affecting up and down reciprocating motion of the rack gear and pumping mechanism. Some forms of the invention include a compressible gas counter-balance arrangement. Some forms of the invention include an electronic drive configured for dealing with electric power generated by the motor during a portion of the pumping cycle.
    • 用于从地层或储层泵送诸如水和/或烃的流体的装置和方法包括具有机械齿条和小齿轮驱动装置的线性杆泵,其适于附接到泵送机构,例如抛光杆 在烃井中的杆串的顶部。 齿条和小齿轮驱动装置的齿条适于与抛光棒连接并与其一起移动。 小齿轮不与齿条平移,并且由用于影响齿条和泵送机构的往复运动的可逆马达驱动。 本发明的一些形式包括可压缩气体反平衡装置。 本发明的一些形式包括电子驱动器,其构造成用于在泵送循环的一部分期间处理由电动机产生的电力。
