The invention relates to a method and a system for determining the hydrocarbon generation amount of a hydrocarbon source rock in an in-situ electric heating process. The method comprises the steps of:acquiring the temperature field of a hydrocarbon source rock in a single-well electric heating process; determining the temperature field of the hydrocarbon source rock in a multi-well electric heating process according to the temperature field of the hydrocarbon source rock in the single-well electric heating process; determining an electric heating hydrocarbon generation conversion rate according to the temperature field of the hydrocarbon source rock in the single-well electric heating process and the temperature field of the hydrocarbon source rock in the multi-well electric heating process; determining different electric heating areas; and determining total hydrocarbon generation according to the electric heating hydrocarbon generation conversion rate and the different electric heating areas. According to the invention, the hydrocarbon generation amount of the hydrocarbon source rock in the in-situ electric heating process can be rapidly and accurately determined.
Description
technical field [0001] The invention relates to the field of calculating the hydrocarbon generation amount of source rocks, in particular to a method and system for determining the hydrocarbon generation amount of source rocks during in-situ electric heating. Background technique [0002] Although my country is rich in shale oil resources, the effective exploration and development of shale oil still faces severe challenges. The main difficulty in exploration and development lies in its development technology. For medium-to-high maturity oil shale, the predecessors have found through exploratory tests that the horizontal well-volume fracturing technology can be used to achieve effective exploration and development. It is currently in the exploration stage, and there is still a large space for technical research before industrialized exploration and recovery. Factors such as geology and engineering play a decisive role in whether the in-situ mining technology can be industrial...
