AI Technical Summary
Existing technologies for evaluating hydrocarbon expulsion efficiency in shale oil and gas resources suffer from computational complexity, difficulty in accurately estimating parameters, and difficulty in distinguishing between unconverted and converted hydrocarbon fractions, resulting in inaccurate evaluations and an inability to incorporate localized characteristics of the well area.
Using a volumetric method, experimental data from underground core samples and crude oil and natural gas samples were obtained. Combined with hydrocarbon generation thermal simulation experiments, the hydrocarbon content per unit volume and mass of rock was calculated, and a formula for calculating hydrocarbon expulsion efficiency was established, including evaluation of oil and gas content, physical property parameters, and calculation of oil and gas generation.
It enables accurate evaluation of shale oil and gas resources, provides a scientific basis for reservoir selection, and makes up for the lack of systematicness and comprehensiveness of existing technologies.
