AI Technical Summary
Technical Problem
In existing heavy oil extraction methods, steam condensation causes clay minerals to expand and migrate, leading to blockage of reservoir pore throats, reduced permeability, low thermal energy utilization efficiency, and low crude oil recovery rate.
Method used
By using a combination of pH adjusting fluid, first solvent and first foaming agent, the crude oil viscosity is reduced by injecting it into the main wellbore and heating the reservoir, thus extending the branch wellbore and achieving waterless extraction.
Benefits of technology
It improves crude oil fluidity and recovery rate, avoids water-sensitive damage, and enhances thermal energy utilization efficiency and extraction efficiency.
