Title: **Yujie Zhu: Innovator in Logging Technology**

Introduction

Yujie Zhu is a notable inventor based in Sichuan, China, who has made significant contributions to the field of logging technology. With a focus on addressing high water cut problems in horizontal wells, Zhu has developed a patent that enhances the efficiency and safety of well logging processes.

Latest Patents

Zhu holds a patent for a "Logging method for locating watered zone in horizontal well with high watercut problem by isotope labeling." This innovative method includes several key operations. Firstly, it involves solidifying an isotope into a water-soluble carrier. Next, the isotope releasing device is connected to tubing and set within the horizontal segment of the well. The carrier is then dissolved in water at the well's bottom, allowing the isotope to be released at a rate proportional to the water flow. Following this, a lift-up pump is started, initiating production logging. Finally, a continuous gamma-ray energy-spectrum analysis is performed on the produced water at the surface to locate the watered zone based on the detected isotopic content. This method significantly reduces operational risks and logging costs while also minimizing platform occupancy time.
