Abstract

The invention discloses a method for simulating and predicting in-situ mining of fluid heating oil shale. The method comprises: establishing a kerogen pyrolysis chemical reaction model; determining unknowns in the kerogen pyrolysis chemical reaction model; An in-situ mining model of oil shale for simulating the change of the unknown is established; numerical solution is performed on the in-situ mining model of oil shale to simulate and predict the in-situ mining of fluid heating oil shale. According to the method of the invention, the change of oil and gas production with time can be calculated, which is convenient for real-time understanding of the whole production process on site. The method according to the invention can provide data support and analysis means for in-situ mining of on-site fluid heating oil shale, and improves oil shale mining efficiency.

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...
