Abstract
The invention discloses an online calibration method of indicator diagram test equipment and a connection structure thereof. In the invention, one standard indicator diagram test equipment is installed on an oil pumping unit tested by online indicator diagram test equipment which needs to be calibrated so that the standard indicator diagram test equipment and the online indicator diagram test equipment can simultaneously collect a load and displacement data of the oil pumping unit during normal working under a same test working condition. Therefore, a standard indicator diagram can be obtained through testing by using the standard indicator diagram test equipment and an online indicator diagram can be obtained through testing by using the online indicator diagram test equipment. A difference of two data can be obtained after comparing the data of the standard indicator diagram with the data of the online indicator diagram. According to the difference, the online indicator diagram test equipment can be calibrated. In the invention, investment is small, a working efficiency high, operation is convenient and calibration precision is high. An influence on the oil pumping unit is small. A labor intensity of operation personnel can be substantially reduced. The method and the connection structure have many other advantages.

Technical field
the present invention relates to a kind of on-line calibration method and syndeton of merit figure testing apparatus, belong to merit figure testing apparatus collimation technique field.
Background technology
merit figure testing apparatus normally is used for the test of rod-pumped well individual well surface dynamometer card.In the digital Construction of oil field, the load-position diagram that utilizes extended immobilization to be installed in the merit figure testing apparatus timing acquiring on the oil pumper calculates the individual well daily fluid production rate, analyzes and the diagnosis oil well condition.Owing to drift can occur behind the long-time stand under load of load elastic body of merit figure testing apparatus, thereby influence the calculating of oil well daily fluid production rate and the analysis of hole condition, so must often calibrate to the online merit figure testing apparatus in scene.The calibration steps of merit figure testing apparatus commonly used is the online merit figure testing apparatus of pulling down from the scene to be demarcated or the error calibrating indoor through special indicator caliberating device at present, according to the error of calibrating it is calibrated simultaneously.This method be at present the most directly, authority's method; But with regard to the calibration of field erected thousands of merit figure testing apparatus; The method exists shortcomings such as investment is big, inconvenient operation, consumed time is long, workload is big, and also exists shortcomings such as being unfavorable for maintenance management, inefficiency.
Summary of the invention
the objective of the invention is to, and a kind of on-line calibration method and syndeton of investing little, high efficiency, the easy to operate and merit figure testing apparatus that calibration accuracy is higher are provided, to overcome the deficiency of prior art.
technical scheme of the present invention is achieved in that the on-line calibration method of a kind of merit figure testing apparatus of the present invention is; Directly the accurate merit figure testing apparatus of a station symbol is installed on the oil pumper that the online merit figure testing apparatus that need be calibrated tested; Make load and the displacement data of two equipment of standard merit figure testing apparatus and online merit figure testing apparatus in the time gathering oil pumper simultaneously under the identical test job condition in operate as normal; Thereby obtain standard merit figure and obtain online merit figure through online merit figure testing apparatus test through the test of standard merit figure testing apparatus; Can obtain the difference of two kinds of data after the data of the data of standard merit figure and online merit figure are compared; This difference is the error of online merit figure testing apparatus, can calibrate online merit figure testing apparatus according to this error.
are according to the on-line calibration syndeton of a kind of merit figure testing apparatus of said method structure; Comprise standard merit figure testing apparatus and the online merit figure testing apparatus that is installed on the oil pumper of operate as normal; Be installed on the oil pumper poliched rod eye of the online merit figure testing apparatus of being equipped with of oil pumper to the stack of its standard merit figure testing apparatus, and the load elastic body of test usefulness of standard merit figure testing apparatus and being installed on the oil pumper by coaxial at the linear load elastic body of online merit figure testing apparatus.
above-mentioned to be installed between standard merit figure testing apparatus and the online merit figure testing apparatus on the oil pumper poliched rod eye and to be connected with communication cable; And an end of communication cable is plugged on the control signal transmission grafting port of standard merit figure testing apparatus, and the other end of communication cable is plugged on the control signal transmission grafting port of online merit figure testing apparatus.
The nominal measuring accuracy of
above-mentioned standard merit figure testing apparatus is higher than the nominal measuring accuracy of online merit figure testing apparatus.
The error of the nominal measuring accuracy of
above-mentioned standard merit figure testing apparatus is less than or equal to 0.2%FS.
are owing to adopted technique scheme; The present invention is through on the oil pumper that the accurate merit figure testing apparatus of a station symbol is installed in the online merit figure testing apparatus that need be calibrated and is tested; And through the load elastic body of the test usefulness of standard merit figure testing apparatus is pressed coaxial installation with the load elastic body of online merit figure testing apparatus; Simultaneously standard merit figure testing apparatus is connected with online merit figure testing apparatus through communication cable; Standard merit figure testing apparatus and online merit figure testing apparatus are operated under the identical test job condition; And the load-position diagram that obtains tested also be the load-position diagram at one time; Like this operating personnel can make things convenient for, the difference on clearly finding out at one time from two resulting load-position diagram of equipment, this difference is the error of online merit figure testing apparatus, operating personnel can calibrate online merit figure testing apparatus according to this error easily.The present invention need not disassemble online merit figure testing apparatus when test and calibrate from oil pumper, reduced the stop time of oil pumper widely, has improved the work efficiency of oil pumper effectively.And the price of the merit figure testing apparatus that the present invention adopted is significantly less than the price of special indicator caliberating device used in the prior art.So, the present invention compared with prior art, the present invention not only has little, the high efficiency of investment, easy to operate, calibration accuracy advantage of higher, but also have less to the work influence of oil pumper, can alleviate advantage such as labor intensity of operating personnel greatly.
