Background technology
Rig is to drive rig using alternating-current variable frequency motor and diesel engine as a kind of NEW TYPE OF COMPOSITE of combined power, for the exploration and development of oilfield well, can be used for the drillng operation of 7000m well depth.The rotating disk of rig drives and adopts independent alternating current generator to drive, and winch, borehole pump adopt Mechanical Driven, have therefore formed combination flooding dynamic formula rig.Rig basic parameter meets SY/T 5609 standards, and main matching component meets API standard, and rig can meet the requirement of new drilling.
Domestic petroleum rig name drilling depth is take 5000m and 7000 meters as main, and its drive form is divided into again mechanical combined type and drives and electric drilling machine.Wherein electric drilling machine has again dividing of direct current electric drilling machine and AC electrical rig, and usually, combined type drives rig need to adopt diesel engine and motor to combine and drives.At a drill site, can, according to electrical network condition and drilling condition, adopt the drilling mode that comprises multiple drilling well drive motors.Wherein, diesel driven is larger to the pollution of environment, and drilling cost is larger.Therefore can change electricity by rig is carried out to oil.In addition, various rigs carry out oil and change when transformation electricity, need to distinguish transformation, if there are various model rigs in oil field, just have various modification schemes.Each rig is transformed respectively, and cost can increase.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide a kind of drilling cost of saving, and reduces environment pollution, and can call disparate modules according to actual conditions, can on electric drilling machine and machinery/combination drill, support the use flexibly; Save oil and changed electric improvement cost.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: provide a kind of drilling machine oil to change electric system, it comprises voltage electricity transforming devices for use, low pressure transformation device, motor unit and Motor Control module; Voltage electricity transforming devices for use comprises high-tension switch cabinet, high-tension transformer, low-tension switch cabinet, reactive-load compensator and harmonic shutter; High-tension switch cabinet access power supply is inputted successively low-tension switch cabinet and reactive-load compensator after high-tension transformer transformation, and harmonic shutter is serially connected on the loop of reactive-load compensator; Low pressure transformation device comprises low-tension switch cabinet, low-tension transformer and the frequency converter of electrical connection successively, the low-tension switch cabinet of its mesolow transformation device and the electrical connection of the low-tension switch cabinet of voltage electricity transforming devices for use; Described motor unit and fluid-flywheel clutch and frequency converter assembling; Configure of frequency AC Drive has refrigeration unit.
In sum, the utlity model has following advantage:
Native system has comprised voltage electricity transforming devices for use and low pressure transformation device, can be according to the condition of on-the-spot electrical network, and select different oil to change electric mode, be applicable to that alternating current generator creeps into, direct current generator creeps into and mechanical compound driving drilling well.
Drilling machine oil changes electricity after transformation, can save drilling cost, reduces environment pollution, beautifies working environment.But oil field is not each well location can configure power network line, now, or need original diesel powered to drive.Therefore oil changes electric rig does not need every bench drill machine all to transform, and only needs the oil of configuration fair amount to change electric installation module, just calls this module when needs are netted electric module, module can be called to other oil again and change on electrical drilling machine unwanted time.And each module can be called flexibly on electric drilling machine and machinery/combination drill, there is no limitation.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of drilling machine oil to change electric system, comprises voltage electricity transforming devices for use, low pressure transformation device, motor unit and Motor Control module.Voltage electricity transforming devices for use comprises high-tension switch cabinet, high-tension transformer, low-tension switch cabinet, reactive-load compensator and harmonic shutter.High-tension switch cabinet access power supply is inputted successively low-tension switch cabinet and reactive-load compensator after high-tension transformer transformation, and harmonic shutter is serially connected on the loop of reactive-load compensator.Low pressure transformation device comprises low-tension switch cabinet, low-tension transformer and the frequency converter of electrical connection successively, the low-tension switch cabinet of its mesolow transformation device and the electrical connection of the low-tension switch cabinet of voltage electricity transforming devices for use; Described motor unit and fluid-flywheel clutch and frequency converter assembling; It is its cooling that configure of frequency AC Drive has refrigeration unit.
In high voltage variable pressure device, arrange high-tension switch cabinet, high-tension transformer, low-tension switch cabinet and oil field reactive-load compensation and harmonic shutter.Each line voltage is more fixing, is generally 10KV grade, and the active force voltage of motor unit and electric drilling machine is generally 600V electric pressure.Therefore high-tension transformer is configured to 10/0.6KV electric pressure.In order to adapt to the different demands of domestic rig, transformer capacity is configured to 1600KVA.High-tension switch cabinet, as the total input-wire unit of 10KV high pressure, has the effect of cut-offfing, isolate, protect rear end electrical equipment.Low-tension switch cabinet is as the outgoing line unit of 600V voltage, low-tension switch cabinet of every transformer configuration, two low-tension switch cabinets altogether.In order to meet the requirement of electrical network to harmonic wave and reactive power, at 600V side configuration reactive-load compensator and harmonic shutter, compensation capacity is set to 3000KVAR, can meet the demand of the most harsh direct current electric drilling machine.
