发明名称 SICKLINE POWER CONTROL INTERFACE
摘要 Embodiments of the present invention generally provide an apparatus, method, and system for operating an electric downhole tool on a non-conductive suppo rt line (slickline) by converting a battery voltage to an output voltage suitab le for operating the tool. In response to receiving a trigger signal, the outpu t voltage signal is applied to the tool. The tool is controlled by varying the output voltage signal according to a power control sequence. Accordingly, electric tools typically requiring surface intervention by an operator via a n electric cable (wireline) may be operated on slickline.
