Title: Innovator Spotlight: Songbao Zhang and His Contribution to Horizontal Well Logging

Introduction: Songbao Zhang, based in Sichuan, China, is a notable inventor recognized for his innovative methods in the field of petroleum engineering. With a focus on addressing the challenges associated with high watercut problems in horizontal wells, Zhang's work contributes significantly to the efficiency and safety of oil extraction processes.

Latest Patents: Zhang holds one patent titled "Logging Method for Locating Watered Zone in Horizontal Well with High Watercut Problem by Isotope Labeling." This patent presents a sophisticated logging device and method that involve several innovative steps. First, an isotope is solidified into a water-soluble carrier within an isotope-releasing device. Next, this device is connected to tubing and set in the horizontal segment of the well. When the water-soluble carrier dissolves, the isotope is released at a rate proportional to the flow rate of the water. A lift-up pump is then activated to begin production logging while continuous gamma-ray energy-spectrum analysis is performed on the produced water. This method enables precise localization of the watered zone in the horizontal well, significantly reducing operational risk and saving time and costs associated with logging.
