The wireless low-power-consumption oil well indicator based on the Zigbee network comprises an acceleration and load synchronous sampling unit, a Zigbee wireless transmission unit, an indicator diagram data storage unit, a solar charging unit, a CPU (central processing unit) acquisition control unit, a system parameter configuration unit and a power supply management unit, wherein the acceleration and load synchronous sampling unit consists of a load sensor, an acceleration sensor and an AD (analog to digital) acquisition and conversion chip. The indicator provided by the invention has the advantages that the field measurement repeatability is good, the reliability is high, the working efficiency is improved, the condition of an oil well can be known in real time, and the remote automatic testing and the remote automatic control of a well site are realized.

Description

technical field [0001] The invention relates to a wireless low power consumption oil well dynamometer in an oil well remote monitoring system. Background technique [0002] The dynamometer diagram is used to monitor the working state of the oil production well in the oil field, and it is a closed curve diagram composed of the relationship between the suspension point load of the oil production machine and the displacement. The dynamometer diagram showing the relationship between suspension point load and displacement is called ground dynamometer diagram or polished rod dynamometer diagram. Oil well dynamometer diagram is an important representation of the working state of the oil well, which can comprehensively reflect the operation status of the downhole oil pump and the exploitation of crude oil. Through analysis, it can be understood whether the oil well dynamics and the selection of various parameters of the oil pumping device are reasonable. [0003] Most of the displa...

Problems solved by technology

The pull-wire measurement stroke has the disadvantages of bulky instrument, high end-break rate, and severe local wear, which causes a lot of inconvenience to the on-site operation; while the installation and disassembly of the angular displacement sensor must be stopped, which is not only cumbersome and inefficient in the operation process, but also shuts down. It will cause changes in well conditions and pump conditions, and the reflected working conditions are somewhat different from normal working conditions, and the operation is unsafe, and accidents often occur. Moreover, the dynamometer diagrams measured by the above schemes are basically single-machine boards, which cannot realize well Field remote automated testing, automated control
