METHOD FOR POWER-BALANCED DIGITIZED AUTOMATICALLY CONTROLLED OIL PUMPING AND OIL-PUMPING ROBOT

摘要

A method for power-balanced, digitized, automatically-controlled oil pumping, and an oil-pumping robot comprising a main engine (15), a decelerator (8), a crank (9), a connecting rod (6), a walking beam (3), a balance arm (7), a derrick (5), a counterweight (2), a base (12), brake equipment (13), a wireline (1), a load sensor (17), a stroke measurer, a safety stop device, and a digital control box (14). Also disclosed is an oil-pumping robot. The present method is safe and reliable and allows for pump self-optimized adjustment of balance and stroke, thus optimizing oil well production, enhancing pump system efficiency, allowing seamless integration with oilfield computer networks, remote data delivery and remote control, simplified operation, convenience, economies of manpower and energy, and greater economic efficiency.
