Title:
EVALUATION METHOD FOR HYDROGEN CONTAINING INGREDIENT, POROSITY AND APERTURE OF SHALE RICH IN ORGANIC MATTERS
Document Type and Number:
WIPO Patent Application WO/2019/184429
Kind Code:
A1
Abstract:
The invention belongs to the technical field of oil and gas development, and discloses an evaluation method for hydrogen containing ingredient, porosity and aperture of shale rich in organic matters. The method comprises: establishing a division scheme of each hydrogen containing ingredient of the shale rich in organic matters, and a quantitative expression method of fluid ingredients, according to the magnetic resonance imaging T1-T2 spectrum differences among kerogen, kerogen containing adsorption oil, different minerals containing aqueous clay, shale, shale dry samples, saturated oil rock samples and saturated water rock samples; taking the T2 spectrum of the saturated shale rich in organic matters as a target, and taking the T2 spectrum of the shale dry sample as a substrate, carrying out substrate inversion to obtain the T2 spectrum of oil in a hole; and on the basis of the T2 spectrum, evaluating the porosity and the pore diameter distribution of the shale rich in organic matters. Compared with the conventional method, the evaluation method disclosed by the invention is characterized in that high innovation and credibility can be shown, and is favorable for improving the analysis of the magnetic resonance imaging on an aspect of shale rock physical measurement.
