Title: The Innovative Contributions of Dexin Qiao
Introduction
Dexin Qiao is a notable inventor based in Beijing, China. He has made significant contributions to the field of petroleum exploitation through his innovative methods. His work focuses on improving the accuracy of oil and gas saturation calculations in fractured reservoirs.
Latest Patents
Dexin Qiao holds a patent for a "Quantitative calculation method for oil (gas) saturation of fractured reservoir." This method involves obtaining fracture porosity and calculating the resistivity index at different depths of a fractured reservoir using known full diameter core data and imaging logging data. The process establishes a percolation network model of matrix and fracture combinations based on pore structure features. By calibrating numerical simulation results with core experiment data, the method enhances the relationship between resistivity index and water saturation. The calculated oil (gas) saturation using this method is 0.67, which is significantly more accurate than the common method that yields 0.49 in some fractured reservoirs. This improvement in accuracy is over 0.18 in the studied fractured reservoir.
