Abstract

In situ heating oil shale for oil recovery is currently one of the most promising oil recovery methods. Among the in-situ heating mining technologies, electric heating technology is relatively mature and widely applied in industrial applications. However, electric heating technology faces energy consumption issues. This study proposes the off-grid photovoltaic power supply system. The results indicate that seasonal changes and photoelectric conversion efficiency will constrain the in-situ modification effect of oil shale electric heating. And the in-situ modification of oil shale was relatively slow in the first winter. But when the reservoir temperature reaches the stage of pyrolysis hydrocarbons and pyrolysis maturity, the winter constraint effect is not obvious. After 1000 days of heating the wells using photoelectric power supply, the production of methane and other gases continues to increase throughout the heating process, reaching 4 × 10⁶ kg and 1.5 × 10⁷ kg, respectively. And off-grid photovoltaic power supply can effectively reduce fossil fuel consumption and greenhouse gas emissions. This demonstrates its potential application in the in-situ modification technology of oil shale by electric heating.
