AI Technical Summary
Existing technologies cannot quickly and quantitatively identify the fluid type of condensate gas reservoirs during drilling, resulting in high exploration and development costs and low efficiency.
By collecting gas logging data, parameters reflecting the differences in hydrocarbon composition between oil, gas and water reservoirs are constructed. A stepwise discrimination method based on statistics is adopted to establish an oil-gas-water discrimination model and a quantitative 'cross' identification chart, thereby achieving efficient quantitative identification of fluid properties in condensate gas reservoirs.
It enables efficient, rapid, and intuitive quantitative identification of fluid properties in condensate gas reservoirs, reducing exploration and development costs and improving identification accuracy.
