Description
technical field
The utility model relates to a kind of oil well machinery, i.e. electric energy accumulator energy-accumulated electric switched workover rig.
Background technology
It is power that current oil-field workover rig all adopts vehicle-mounted Diesel engine, by gear, angle transmission mechanism and Cold Oil Electronic Cylinder, drive winch drum, there is following problem in the plant equipment that this vehicle-mounted Diesel engine is power: 1, diesel emission is seriously polluted: it is power that the wheeled workover rig of front XJ90Z adopts engineering diesel engine, installed power is 269kW, by europe I standard, designs.If every annual construction 150 days of equipment, diesel engine on average uses power 60% to calculate, approximately 2 tons of the carbon monoxide of every annual discharge, approximately 0.6 ton of hydrocarbon, approximately 4 tons of other materials.These emission of substance are all to environment, extremely harmful to the mankind's existence.2, the inefficiency of diesel engine self: the operating principle of diesel engine is that diesel oil is burnt in the cylinder thermal change that produces becomes the mechanical movement of piston, in this energy conversion process, only has the energy of 30% left and right to change into mechanical energy.3, use, the maintenance cost of vehicle-mounted Diesel engine formula workover rig are high, and an annual cost of a vehicle carried well repairing machine of conventional maintenance is greatly about 3～50,000 yuan, and a series of parts such as diesel engine, power takeoff, gearbox all need maintenance, repair.Be generally 7 years the application life of motor, gearbox.Every operation a bite well needs about 300 liters of diesel oil, approximately 1500 yuans of market values.4, transmission system inefficiency.The power of vehicle-mounted Diesel engine, realizes workover treatment by power takeoff, fluid torque-converter, mechanical gear box, angle transfer gear box and cable drum, assembly pulley.Mechanical transmission course is long, and mechanical resistance loss is large.The machinery driving efficiency of common vehicle-mounted diesel oil workover rig is 0.6 left and right.5, working method efficiency is low.Because power resources are in diesel engine, common working method is that work every day starts soon diesel engine starting, no matter actual operation is promote operation or transfer operation, all need to have the lay day of suspended object, really need normally 1:3 of ratio that workover rig promoted and transferred activity duration and artificial lay day, mean working method, diesel engine will have 75% above time in no-load running, and the diesel oil now expending accounts for fully loaded 30% left and right.
At present, electric workover rig is PetroChina Company Limited., China Petrochemical Industry's equipment development direction, existing because domestic well site power supply is mostly at 30-50kW, so the electric workover rig of producing needs external High-Voltage Network electricity mostly, and with car band transformer.From secure context, do not allow directly to access high-voltage fence, and working rig power is larger, front end power issue is the immediate cause that hinders electric workover rig exploitation, must seek a kind of feasible scheme and solve the little problem of electrical network networking transformer efficiency.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, the electric energy accumulator energy-accumulated electric switched workover rig of powering effective for above-mentioned deficiency.
Technical solution of the present utility model is: the drive motors of electric energy accumulator energy-accumulated electric switched workover rig adopts EI-355 (60T)-6G variable-frequency motor, by gear, angle transmission mechanism and Cold Oil Electronic Cylinder, drives winch drum; Accumulation of energy electric power system is connected with drive motors, and accumulation of energy electric power system is EI-PPS700-17C power-supply management system.
The utility model has the advantages that: 1, select EI-PPS700-17C power-supply management system and Storage Unit, possess static quick charge and dynamic quick discharge function, dependable performance, powers effective.2, on car, be furnished with generating set, can realize hybrid power and drive, convenient, flexible.3, workover rig adopts without guy wire structure, can meet the job requirements of wellsite operation limited space system.4, meet country to the higher requirement of energy-saving and emission-reduction proposition and along with the diesel-fuel price of international raw oil market is constantly soaring, workover rig to traditional engineering diesel powered undergoes technological transformation, and meets national policy, complies with international trend, is conducive to the performance of enterprises and social benefit.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model plan structure sketch.
The specific embodiment
Referring to Fig. 1, component title is as follows: accumulation of energy electric power system 1, drive motors 2, winch drum 3, inversion system 4, automobile chassis 5.
Referring to Fig. 1, the drive motors 2 of electric energy accumulator energy-accumulated electric switched workover rig adopts EI-355 (60T)-6G variable-frequency motor, by gear, angle transmission mechanism and Cold Oil Electronic Cylinder, drives winch drum 3; Accumulation of energy electric power system 1 is connected with drive motors 2, and accumulation of energy electric power system 1 is EI-PPS700-17C power-supply management system.All Plant arrangements are on vehicle-mounted chassis 5.
