Development of a cuttings migration simulation device based on electrical resistance tomography technology

Monitoring cuttings migration in boreholes is crucial for ensuring the safety and efficiency of oil drilling operations. This paper details the design of a borehole cuttings migration monitoring simulation system based on Electrical Resistance Tomography (ERT) technology. The system includes a cuttings circulation module that ensures the continuous migration of cuttings within the system, and a cuttings monitoring module that employs ERT technology. By arranging an array of electrodes around the borehole, the monitoring module obtains real-time resistivity data and its variations, processes this data, and generates images on the host computer. The aim is to quantitatively and qualitatively analyze the state of cuttings migration in the borehole through measurement technology. Experimental results demonstrate that the system can accurately and effectively capture the trajectory of cuttings migration, providing reliable data support and a theoretical basis for drilling safety management and cuttings migration research.
