Title: Liguo Zhou: Innovator in Slow Rate Pumping Technology
Introduction
Liguo Zhou is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of pumping technology, particularly in the development of slow rate pumping systems. With a total of 3 patents to his name, Zhou's work has the potential to enhance efficiency in various industrial applications.
Latest Patents
Zhou's latest patents focus on a method and system of slow rate pumping. This innovative system includes a discharge line that receives a discharge flow of displacement fluid from a high rate pumper. It also features a return line off the discharge line to receive a return flow of displacement fluid. Additionally, a slow rate diversion pumping line is incorporated to supply a diversion flow of displacement fluid downhole. The system is equipped with a return valve to control the return flow and a diversion valve to manage the downhole flow. The method involves receiving a main pumping flow through a return line at a pumping pressure, producing a differential pressure between the pumping pressure and a downhole pressure that matches a differential setpoint. It also includes diverting a slow rate flow of fluid from the main flow using a diversion line off the return line prior to the return valve, while maintaining the differential pressure.
