Description
Technical field
The present invention relates to producing well technical field of measurement and test, specifically a kind of oil well spillage re-injection device.
Background technology
Oil field was when lower wireline test operation in the past, the spillage that lubricator top is flowed out is collected and focuses on together or outwell, along with the progress in epoch, environmental requirement strict, because the restriction of situ of drilling well working environment proposes a difficult problem to the process of oil well spillage, and the crude oil of spilling to be noted go back to again down-hole be best processing mode, this just needs set of device smoothly the crude oil that oil well overflows can be noted go back to down-hole.
Summary of the invention
The object of the invention is to provide a kind of oil well spillage re-injection device for the problems referred to above, by realizing the fluid injection of suction high pressure to structures such as hydraulic cylinder, fluid injection cylinder, solenoid operated directional valve, liquid sucting valve, tapping valves in device, and then solution oil well spillage notes back down-hole problem smoothly.
The technical solution adopted in the present invention is: a kind of oil well spillage re-injection device comprises hydraulic pump, overflow valve, unidirectional valve, solenoid operated directional valve, hydraulic jack, center-pole, travel switch, fluid injection cylinder, imbibition one way valve, discharge opeing one way valve, liquid injection pipe, catch box, piston a, piston b are formed; It is characterized in that power source drives first class reducer, reductor drives hydraulic pump, and pressure oil got by hydraulic pump, passes to hydraulic jack by solenoid operated directional valve, overflow valve; Hydraulic jack inner carrier a carrys out the reciprocating motion of control piston a by travel switch and solenoid operated directional valve; Hydraulic jack inner carrier a drives fluid injection cylinder inner carrier b to move back and forth circulation of finishing the work by center-pole; Fluid injection cylinder carrys out imbibition and the fluid injection of hydraulic control oil cylinder by imbibition one way valve and discharge opeing one way valve.
Described fluid injection cylinder adopts bimetallic manufacture to form, and inboard wall of cylinder block is alloy material, can reach wear-resisting, prevents advantages such as pulling, to improve the application life of steel.
Described piston a, piston b use acid and alkali-resistance, and abrasive rubber and polyamide skeleton are made, and sealing is reliable, wear-resistant, and tension is hindered.
Described imbibition one way valve, discharge opeing one way valve are controlled by two non-return valves, it is characterized in that the inner chamber body space of valve is large, are provided with spring reset.
The invention has the beneficial effects as follows: owing to taking such scheme, solve oil well spillage and note back down-hole problem smoothly, the environmental issue of situ of drilling well is solved.
