Description
Technical Field
The invention relates to a device for testing an indicator diagram of a pumping well, in particular to a wireless integrated device for testing the indicator diagram of the pumping well.
Background
In the oil extraction operation of the oil pumping unit, the indicator diagram of the oil pumping unit well needs to be monitored in real time. At present, one means for testing the indicator diagram of a beam-pumping well is as follows: a load sensor is arranged at the joint of the polished rod and the polished rod eye to measure the load of the polished rod, and an angular displacement sensor is arranged on the walking beam to measure the displacement of the polished rod; the load and displacement are measured to form a load displacement curve synchronous with stroke frequency of the pumping unit, namely an indicator diagram. The prior method can obtain a relatively accurate indicator diagram, but has the following problems: 1. the load sensor directly bears the load of the polished rod, and in each stroke cycle, when the polished rod stops being blocked when the polished rod descends in each stroke cycle under the working condition that the beam pumping unit is blocked (such as sand jam, viscosity and the like), the rope hanger continues to descend to cause the load sensor to be unloaded, and then when the polished rod ascends, the rope hanger is suddenly lifted to instantly load and impact the load sensor, so that the repeated impact easily causes damage to the load sensor and shortens the service life of the load sensor; 2. the load sensor and the angular displacement sensor are used for testing, the polished rod displacement testing precision is high, but the split structure is complex, and the hardware comprehensive cost is high.
Disclosure of Invention
The invention aims to provide a wireless integrated indicator diagram testing device for a beam-pumping unit well, which does not directly bear the load of a polished rod when in use and cannot be impacted by the load under the working condition that the pumping unit is in running blockage.
In order to achieve the purpose, the invention adopts the following scheme: the wireless integral beam-pumping well indicator diagram testing device is provided with a wireless angular displacement sensor and a strain sensor, wherein a high-energy battery, a circuit board, an inclination angle chip and a communication module are arranged in a shell of the wireless angular displacement sensor, the high-energy battery, the inclination angle chip and the communication module are respectively connected with corresponding interfaces on the circuit board, an antenna is fixed on the outer side of the shell and connected with the communication module, and a signal output end of the strain sensor is connected with a corresponding signal interface on the circuit board through a cable.
When the indicator diagram testing device is used, the wireless angular displacement sensor and the strain sensor are both arranged on a walking beam of the oil pumping unit, the circuit board supplies power to the strain sensor, the inclination angle chip acquires angular displacement data of the walking beam, the strain sensor tests the strain data of the walking beam, the circuit board converts the strain data into load data of a polished rod, and then the load data and the angular displacement data are processed to form indicator diagram data which are then transmitted to a local remote measurement and control terminal (RTU) or directly and remotely transmitted to a data measurement and control center by the communication module and the antenna, so that an indicator diagram can be obtained; because the wireless angular displacement sensor and the strain sensor do not directly bear the load of the polished rod, the pumping unit cannot be impacted by the load under the working condition that the pumping unit is in operation and is in blockage.
The invention has reasonable structure, reliable performance, convenient and quick installation, debugging and maintenance and lower comprehensive cost, is suitable for all beam-pumping wells, and particularly can not be damaged by impact under the working condition that the beam-pumping unit is in operation and meets with a resistance, thereby ensuring ideal service life.
