AI Technical Summary

Technical Problem

Existing cementing plugging agent performance testing equipment cannot visually observe the cementation of fractured rocks under dynamic conditions, and cannot effectively evaluate the performance of cementing plugging agents, leading to frequent well leakage accidents.

Method used

A performance evaluation device for cemented plugging agent was designed, comprising a central tube, a pore tube, and a wellbore tube. By simulating downhole plugging conditions and the filtration loss of the cemented plugging agent, the device structure was designed using 3D modeling software, and flow simulation was performed to optimize the device for observing the filtration loss and plugging capacity of the cemented plugging agent in the pores.

Benefits of technology

It enables performance evaluation of cemented plugging agents under dynamic conditions, allowing observation of pore loss and plugging capacity, guiding the selection of optimal formulations, and reducing drilling accidents.
