Title: Chang Guo: Innovator in Gas Extraction Technologies
Introduction
Chang Guo is a prominent inventor based in Jiangsu, China, known for his significant contributions to gas extraction technologies. With a total of 4 patents, he has developed innovative methods that enhance the efficiency of coalbed gas extraction.
Latest Patents
One of his latest patents is a method for gas extraction using alternating oscillating pulse high energy gas extraction with thermal injection. This method employs high energy gas fracturing technology to create a fracture network in a thermal injection borehole. High-pressure, cyclically temperature-changing steam is injected into the borehole through a spinning oscillating-pulse jet nozzle, generating oscillating superheated steam. This steam alternately impacts and heats the coal body, facilitating gas desorption and extraction efficiency.
Another notable patent is the method for integrated drilling, flushing, slotting, and thermal injection for coalbed gas extraction. This innovative approach combines drilling, flushing, and slotting with thermal injection to improve gas extraction from microporous, low-permeability, high-adsorption coalbed areas. By monitoring concentration variations in the gas extraction borehole and injecting high-temperature steam, this method significantly enhances gas permeability and promotes efficient gas flow.
