METHOD AND APPARATUS FOR PREDICTING YIELDS OF PETROLEUM AND GAS IN INTRA-RESERVOIR DEVELOPMENT OF OIL SHALE

摘要

FIELD: petroleum industry.;SUBSTANCE: invention relates to the field of petroleum survey. Disclosed is a method for predicting yields of petroleum and gas in intra-reservoir development of oil shale, including: obtaining the initial total organic carbon (TOC) value, the vitrinite reflection indicator (Ro) value, and the initial value of the hydrogen index (HI) of the shale subject to measuring; obtaining the petroleum yield for the shale subject to measuring based on the initial TOC value, the Ro value, the initial HI value of the shale subject to measuring, and a pre-installed model for predicting the petroleum yield in intra-reservoir development of oil shale, wherein the model for predicting the petroleum yield in intra-reservoir development of oil shale is established preliminarily based on the data on the petroleum yield, obtained by conducting a simulation temperature modeling experiment on multiple different shale samples, and the initial TOC value, the Ro value and the initial HI value of the shale samples; and obtaining the gas yield for the shale subject to measuring based on the initial TOC value, the Ro value, the initial HI value of the shale subject to measuring, and the preliminarily established model for predicting the gas yield in intra-reservoir development of oil shale, wherein the model for predicting the gas yield in intra-reservoir development of oil is established preliminarily based on the data on the gas yield, obtained by conducting a simulation temperature modeling experiment on multiple different shale samples, and the initial TOC value, the Ro value and the initial HI value of the shale samples.;EFFECT: provided increase in the accuracy of predicting yields of petroleum and gas in intra-reservoir development of oil shale.;15 cl, 11 dwg, 1 tbl
