AI Technical Summary

Technical Problem

Existing offshore platform sampling devices are prone to clogging of sampling channels due to factors such as solid particle deposition and wax precipitation, which affects sample collection, causes safety hazards, increases operation and maintenance costs, and cannot obtain true multiphase flow composition data.

Method used

The system employs a mechanical structure design, including a dynamic anti-clogging device and an intelligent sampling system. It utilizes springs and tension springs to drive the sealing column to slide and clean the inner wall of the top pipe, and a motor drives the sealing column to reciprocate and clean the horizontal pipe. Combined with pressure regulation and intelligent valve control, it achieves automated and precise sampling of multiphase flow.

Benefits of technology

It enables automated and precise sampling of multiphase flow components, prevents clogging, ensures sample representativeness, reduces operation and maintenance costs, and improves production safety and efficiency.
