Latest Patents
One of Guo's latest patents is for an electropositive production well treating fluid and method of preparing the same. This invention features a water-based production well treating fluid system that exhibits electropositivity by utilizing a cationic viscosifier. It is designed to address the technical requirements of treating fluid stability and bore hole stability. The fluid demonstrates a strong ability to inhibit clay dispersion, protect oil-gas reservoirs, and maintain fast drilling speeds while ensuring regular bore hole shapes and good salt resistance.
Another significant patent by Guo is an automatic control system and method for bottom hole pressure in underbalanced drilling. This invention leverages computer automatic control technology to manage bottom hole pressure (BHP) effectively. The system calculates BHP based on various hydraulic mechanisms and compares it with a set pressure value. If the BHP deviates from the set range, the system automatically regulates the throttle valve opening to maintain optimal pressure levels.
