Abstract

The invention discloses a simulating and forecasting method for fluid-heating oil-shale in-situ mining. The method includes the steps that a kerogen pyrolysis chemical reaction model is established; the unknown number in the kerogen pyrolysis chemical reaction model is determined; an oil-shale in-situ mining model for simulating unknown number changes is established; the oil-shale in-situ mining model is subjected to numerical solution, so that simulating and forecasting of the fluid-heating oil-shale in-situ mining are carried out. According to the simulating and forecasting method, changes of the oil and gas yield following time can be calculated, and the whole production process is conveniently understood on the scene in real time; a data support and analysis means can be provided for scene fluid-heating oil-shale in-situ mining, and the oil-shale mining efficiency is improved.

Description

technical field [0001] The invention relates to the field of geological development, in particular to a simulation prediction method for in-situ mining of fluid heating oil shale. Background technique [0002] After entering the 21st century, countries all over the world have increasing demand for energy, the world's oil and natural gas resources are gradually depleting, and the world's conventional energy supply situation is becoming increasingly severe. Therefore, the research on unconventional energy has been regarded as an important topic in the development of alternative energy in the new century in the world. [0003] Oil shale, also known as kerogen shale, is a kind of sedimentary rock containing combustible organic matter. As an unconventional energy source, oil shale resources are very rich in the world. According to incomplete statistics, its reserves are about 10 trillion tons. If it is Converted into shale oil, the world's oil shale reserves are about 550 billio...
