Title: Weining Ni: Innovator in Downhole Imaging Technologies

Introduction

Weining Ni is a prominent inventor based in Beijing, China, known for his contributions to downhole imaging technologies. With a total of 3 patents, he has made significant advancements in the field of resistivity measurement while drilling.

Latest Patents

One of his latest patents is the "Downhole multidimensional imaging feature extraction method and imaging apparatus." This innovative apparatus is designed to acquire formation resistivity signals, ultrasonic echo signals, and orientation signals regularly. It includes a sector calculation unit that determines the sector from which the currently acquired signal originates. The multi-dimensional imaging unit processes the acquired signals to calculate resistivity data, distance from the drilling tool to the borehole wall, and ultrasonic echo amplitude. This data is then distributed across all sectors for feature recognition and extraction, allowing for the identification of key features of the formation being drilled. These features are transmitted to the surface to guide the drilling process, thereby reducing the structural complexity and length of the downhole imaging measurement instrument.

Another notable patent is the "Resistivity measurement while drilling device and method." This device features a transmitting module that generates an induced current between the drill collar and the surrounding formation through inductive coupling. It includes a receiving electrode group with multiplexing electrodes that receive the measured current. A resistivity calculation module calculates the resistivity of the formation based on the measured current, while a data transmission module sends the calculated resistivity to a ground device.
