The invention relates to the technical field of producing well test and provides an oil well effluent liquid backfilling device which comprises a hydraulic pump, an overflow valve, a one-way valve, an electromagnetic directional valve, a hydraulic cylinder, a center rod, a travel switch, a liquid filling cylinder, a liquid suction one-way valve, a liquid discharge one-way valve, a liquid filling pipe, a liquid collection tank, a piston a and a piston b. The oil well effluent liquid backfilling device is characterized in that a primary speed reducer is driven by a power source, the hydraulic pump is driven by the speed reducer so as to pump out pressure oil, and the pressure oil is conveyed to the hydraulic cylinder by virtue of the electromagnetic directional valve and the overflow valve; <0}{0><}0{>the reciprocating motion of the piston a in the hydraulic cylinder is controlled by virtue of the travel switch and the electromagnetic directional valve; the piston a in the hydraulic cylinder drives the piston b in the liquid filling cylinder to perform reciprocating motion by virtue of the center rod so as to finish operating cycle; the liquid filling cylinder is capable of controlling the liquid suction and liquid filling operations of the hydraulic cylinder by virtue of the liquid suction one-way valve and the liquid discharge one-way valve. <0}{0><}0{>The oil well effluent liquid backfilling device has the beneficial effects of smoothly backfilling an oil well effluent liquid into an oil well and thus solving the environment protection problem of a drilling site.
Description
technical field [0001] The invention relates to the technical field of oil production well testing, in particular to an oil well overflow fluid reinjection device. Background technique [0002] In the past, when the oil field was running the cable test operation, the overflow liquid flowing from the top of the blowout pipe was collected together for centralized treatment or dumped. With the progress of the times, the environmental protection requirements are strict, and the treatment of the oil well overflow liquid is limited due to the limitation of the working environment of the drilling site. A difficult problem has been raised, and it is the best way to deal with the spilled crude oil back down the well, which requires a set of devices that can smoothly inject the crude oil spilled from the oil well back down the well. Contents of the invention [0003] The object of the present invention is to provide an oil well overflow liquid reinjection device for the above proble...
