基于地磁感应的柱塞到达传感器设计
Design of Plunger Arrival Sensor Based on Geomagnetic Induction
摘要
Abstract
Plunger arrival detection is an important component of the plunger gas-lift drainage and gas production process.In order to solve the problem that the traditional plunger arrival sensor is easily affected by the oil pipe vibration,which leads to the low production efficiency of gas-lift wells,a design method of plunger arrival sensor based on geomagnetic induction is proposed.The plunger arrival sensor is based on STM32 microprocessor.The data transmitted by the geomagnetic sensor RM3100 is collected,and the adaptive threshold algorithm is adopted to judge the motion state of the plunger after moving average filtering.Finally,the plunger arrival signal is output.The laboratory test and field application show that the plunger arrival sensor has high detection accuracy and stable operation,and has certain practical value in the plunger gas-lift drainage and gas production technology.关键词
