Abstract

The invention discloses an acceleration-based indicator diagram data acquisition device of an oil pumping unit. The device comprises a singlechip, an acceleration sensor arranged on a polish rod of the oil pumping unit, a load sensor and a power module for supplying power, wherein the singlechip comprises a timer; the device is characterized in that: the indicator diagram data of the oil pumping unit is calculated by the following steps of: acquiring the acceleration and real-time load; calculating the average of multiple adjacent accelerations; calculating the zero value of the acceleration; integrating to obtain the speed; integrating to obtain an upper stroke and a lower stroke; equally dividing into multiple points according to distance; and adding the load corresponding to the point to obtain the indicator diagram data of the oil pumping unit. In the acceleration-based indicator diagram data acquisition device of the oil pumping unit disclosed by the invention, by improving the algorithm, the stroke and stroke frequency of the oil pumping unit are calculated simply by adopting the acceleration sensor to acquire the acceleration, and the accuracy and operability are greatly improved. Moreover, the device is convenient to install and use through a wireless transmission mode and a solar cell power supply mode.

Description

technical field [0001] The invention belongs to the field of oilfield acquisition, and in particular relates to an acceleration-based power diagram data acquisition device for a pumping unit. Background technique [0002] The power map data of the pumping unit refers to the stroke and load data of the polished rod of the pumping unit, which is the data that must be collected by equipment such as the wireless dynamometer of the oil well. At present, the method of collecting the power diagram data of the pumping unit is basically realized through the angular displacement sensor. For example: Tangshan Pingsheng Electronic Technology Development Co., Ltd. produces the power map and oil measurement transmission system, which can transmit the actual measured work map data of the oil well to the background network through GPRS. The angular displacement sensor measures the displacement data in real time, and the load sensor measures the load data in real time to form a map. curve. ...
