Title: Innovations of Inventor Hui Wu

Introduction

Hui Wu is a prominent inventor based in Beijing, China. He has made significant contributions to the field of drilling technology, holding a total of seven patents. His work focuses on improving the efficiency and effectiveness of downhole transmission devices used in measurement-while-drilling (MWD) applications.

Latest Patents

One of Hui Wu's latest patents is a method of encoding and decoding downlink instructions based on mud flow rate. This innovative method includes both an encoding and a decoding process that allows for the transmission and reception of instructions by controlling the mud flow rate during drilling. Notably, this method does not rely on a fixed voltage threshold for determining '0' and '1' symbols. Instead, it uses the voltage change rate as a standard for judging level transitions, which helps avoid decoding failures that can occur when voltage sampling values do not reach the fixed threshold at greater well depths.

Another significant patent is the service table for polling data of downhole transmission devices in MWD. This service table includes various parameters such as frame numbers, data item counts, and device addresses. It has been successfully implemented in actual drilling devices, completing field operations for multiple wells. Compared to previous simplified service tables, this architecture supports multiple downhole transmission devices working simultaneously, thereby enhancing drilling efficiency and reducing costs.
