Description

Technical Field

[0001] The invention relates to a pumping unit well dynamometer diagram testing device, in particular to a wireless follow-up walking beam type pumping unit well dynamometer diagram testing device. Background Art

[0002] During the oil production operation of the pumping unit, it is necessary to monitor the dynamometer diagram of the pumping well in real time. The basic structure of an existing dynamometer diagram test device for a beam pumping well is as follows: a carrier body is provided with a "U"-shaped notch, a block is installed on the carrier body, the block closes the opening of the "U"-shaped notch to form a mounting hole, a shell is connected to the other side of the carrier body opposite to the "U"-shaped notch, a circuit board and a battery are arranged in the shell, the circuit board is connected to the battery, a communication module and an acceleration chip are connected to the circuit board, a strain column is installed on the carrier body, a strain gauge is attached to the strain column, and the strain gauge is connected to the circuit board. When in use, this dynamometer diagram test device is installed on the light rod of the pumping unit, collects load data and acceleration displacement data, transmits the data to the on-site control terminal or the data control center, and obtains the dynamometer diagram.

[0003] At present, in the operation of the pumping well, due to various reasons, the wear of the polished rod of the pumping unit will have eccentric wear, which will shorten the service life of the polished rod and shorten the maintenance-free period of the oil well. In order to reduce the degree of eccentric wear of the polished rod, an effective means currently adopted is to improve the pumping unit so that the polished rod can rotate continuously when it reciprocates up and down during operation, thereby achieving uniform wear of the polished rod. After this improvement, it is required that the dynamometer test device installed on the polished rod also rotates with the polished rod. The above-mentioned dynamometer test device is installed on the polished rod, and there are the following problems: with the mounting hole as the center, the outer dimensions of the circumference of the mounting hole are uneven, the space occupied by the shell on one side of the mounting hole is large, and the spacing of the two suspension ropes of the pumping unit suspension rope is smaller than the rotation radius of the shell. When the dynamometer test device rotates with the polished rod, the shell will be blocked by the suspension rope and is difficult to rotate. Summary of the invention

[0004] The object of the present invention is to provide a wireless follow-up walking beam pumping unit well dynamometer test device, the maximum rotation radius of the dynamometer test device is small.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following scheme: a wireless follow-up walking beam pumping well indicator diagram test device, the indicator diagram test device has a carrier, a "U"-shaped notch is opened on the carrier, a strain column is installed on the carrier, a strain gauge is attached to the strain column, a battery compartment is connected to one side of the open end of the "U"-shaped notch of the carrier, the battery compartment closes the "U"-shaped notch to form a mounting hole, a battery is installed in the battery compartment, a circuit board compartment is connected to the other side of the carrier away from the battery compartment, a circuit board is arranged in the circuit board compartment, a communication module and an acceleration chip are connected to the circuit board, the strain gauge on the strain column is connected to the corresponding signal interface on the circuit board, and the battery is connected to the power interface of the circuit board.

[0006] As can be seen from the above scheme, the present invention arranges the battery compartment and the circuit board compartment symmetrically with the mounting hole as the center, which reduces its own maximum rotation radius and solves the problem of being blocked by the suspension rope when rotating with the light rod in use. The present invention is installed on the light rod of the pumping unit. When it rotates with the light rod, it collects the load data and acceleration displacement data of the light rod, and then processes the load data and acceleration displacement data to form the indicator diagram data. The communication module transmits the indicator diagram data to the remote measurement and control terminal (RTU) or directly transmits it to the data measurement and control center to obtain the indicator diagram.

[0007] The invention has reasonable structure and reliable performance, can rotate safely with the light rod, is convenient and quick to install, debug and maintain, and has low overall cost. BRIEF DESCRIPTION OF THE DRAWINGS
