A method and system for correcting hydrocarbon content in shale oil and gas formations
ActiveCN120020542BImplement loss correctionachieve correctionWithdrawing sample devicesMaterial thermal analysis
This invention provides a method and system for correcting hydrocarbon content in shale oil and gas formations. The method involves dividing the formation into sub-segments based on different core sampling intervals and collecting cores using both pressure-controlled closed core sampling and conventional core sampling methods. Pyrolysis is performed on the collected samples to obtain hydrocarbon content at different temperatures. The relationship curve between hydrocarbon content and total oil content in a single temperature range for pressure-controlled closed core sampling is used as the baseline hydrocarbon content relationship. The relationship curve between hydrocarbon content and total oil content in a single temperature range for conventional core sampling is used as the target hydrocarbon content relationship. The slope of the target hydrocarbon content relationship curve and the baseline hydrocarbon content relationship curve is analyzed to determine the hydrocarbon content requiring correction, and a correction coefficient is determined based on the slope. Therefore, a hydrocarbon content correction calculation model for conventional core sampling in different core segments is determined based on the correction coefficient. This scheme effectively overcomes the problems of high time and manpower consumption and insufficient data accuracy in existing hydrocarbon recovery technologies, achieving reliable hydrocarbon loss correction through simple operation.
