摘　　要：通过随钻测量工具获取井下工程参数是准确掌握井筒信息的有效手段,基于微机电系统(micro-electromechanical systems,MEMS)技术,研发一款集井下温度、压力、磁场和动力学信号测量为一体的微型测量器,以实现对井下多个物理场的协同测量,最终目的是通过多维数据的分析进行井下复杂工况的判断。通过室内管柱循环试验测试,对微型测量器的移动高效性和功能完整性进行验证。结果表明,获得的测量数据可以较好地反映井下漏失、溢流等复杂情况。Measurements of downhole engineering parameters while drilling are important for obtaining the wellbore information.In this work,a microchip measuring device integrating the measurements of downhole temperature,pressure,magnetic field and other dynamic signals was developed based on the micro-electromechanical systems(MEMS)technology,in order to realize a collaborative measurement of multi-physical fields downhole during well drilling process,whose ultimate purpose is to evaluate the complex working conditions downhole via the analysis of multi-dimensional measurement data.Based on indoor drilling fluid circulation loop testing,the efficiency and functional integrity of the microchip measuring device were verified,in which some complex downhole scenarios,such as downhole leakage and overflow,can be well reflected by the measured data.
