Abstract
The utility model discloses a take out surplus oil mass estimation device of well between oil field, including converter, touch -sensitive screen, LED lamp, IM motor and belt formula beam -pumping unit, the touch -sensitive screen pass through the RS485 bus with the converter is connected, a digital output terminal of converter is connected the negative pole of LED lamp, the positive pole of LED lamp, the 2nd digital output terminal ground connection are connected to the power, the three -phase output of converter is connected the IM motor, the output shaft of IM motor belt formula beam -pumping unit. Use the system, the surplus oil mass of taking out the well between the oil field that can change at any time to the oil mass is made and being appraised, lasts when low when the oil mass, in time reports to the police or automatic shutdown oil pumping process, can effectively avoid the beam -pumping unit to take place the sky and take out the phenomenon that wear and tear polished rod and pump pole were managed, has reduced energy loss in addition.
Description
Technical field
The utility model relates to the mining equipment of oilfield, is specifically related to a kind of device estimating the Fuel Oil Remaining taking out well between oil field.
Background technology
In existing oil well, take out well and occupy certain ratio, taking out well can not one day 24 hours output oil, stop well and wait for that oil well PetroChina Company Limited. continues oil pumping after oozing out again after needing each fuel-displaced a period of time.In the prior art, how long fuel-displaced oil well is, entirely relies on experience by the old skilled worker in oil field, and the special equipment according to costliness judges in conjunction with oil well oil pump capacity, and just can need reach a conclusion through repeatedly observing.Simultaneously because oil well state is easy to change, easily cause the phenomenon of the waste of larger error and oil and power resource, and efficiency comparison is low.
Utility model content
For the deficiencies in the prior art, the utility model discloses the Fuel Oil Remaining estimating device taking out well between a kind of oil field.
The technical solution of the utility model is as follows:
Take out a Fuel Oil Remaining estimating device for well between oil field, comprise frequency converter, touch-screen, LED, IM motor and belt type pumping unit; Described touch-screen is connected with described frequency converter by RS485 bus; Described frequency converter comprises digital output terminal and three-phase output end; The digital output terminal of frequency converter comprises the first digital output terminal and the second digital output terminal, the negative pole of LED described in described first digital output end sub-connection, and power supply connects the positive pole of LED, described second digital output terminal ground connection; The three-phase output end of frequency converter connects described IM motor; The output shaft of described IM motor connects described belt type pumping unit.
Advantageous Effects of the present utility model is:
Use device described in the utility model, the Fuel Oil Remaining taking out well between the oil field that can change at any time to oil mass makes estimation, when oil mass continues too low, and alarm or automatically stop oil pumping process, effectively can avoid oil pumper that empty phenomenon of taking out wearing and tearing polished rod and pump rod pipe occurs, and reduce energy loss.The utility model is for the judgement of Fuel Oil Remaining than repeatedly judged by artificial experience in prior art will more accurately and convenient, and the utility model has, and data show in real time, the advantage such as simple to operate, easy to implement, energy-conservation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is LED warning circuit wiring diagram.
Detailed description of the invention
Fig. 1 is schematic diagram of the present utility model, and the utility model comprises touch-screen, LED, frequency converter, IM motor and belt type pumping unit; Touch-screen is connected with frequency converter by RS485 bus, and the output of frequency converter comprises digital output terminal and three-phase output end, and digital output terminal is connected with LED, and three-phase output end connects IM motor, and the output shaft of IM motor connects belt type pumping unit.
In Fig. 1, the effect of each ingredient is as described below:
Touch-screen: for setting parameter and the monitoring of frequency converter;
LED: remind for the low oil mass state of oil well;
Frequency converter: for driving IM motor, gathers and the parameter such as running time, power output, power factor, DC bus-bar voltage of tape deck.Due to device running time, power output, power factor, DC bus-bar voltage etc. parameter and the Fuel Oil Remaining of oil well have correlation, so frequency converter can perform internal algorithm based on these operational factors, make comparisons with the oil mass standard preset, estimation oil well Fuel Oil Remaining; Described algorithm is prior art.
IM motor: drive belt type pumping unit acting;
Belt type pumping unit: the direct acting device of oil well oil-pumping.
Fig. 2 is the circuit interconnect pattern of LED, and the part shown in Fig. 2 can regard as warning circuit, and the digital output terminal R2A of frequency converter connects the negative pole of described LED, and+24V power supply connects the positive pole of LED; Digital output terminal R2C ground connection.
This device is by the operational factor of frequency converter harvester, and the Fuel Oil Remaining in real-time estimation oil well, when Fuel Oil Remaining meets the low oil mass standard of setting in advance, sends warning by LED, can select automatically to stop oil pumping simultaneously.
Above-described is only preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection domain of the present utility model.
