Abstract
Electrical heating-induced in-situ conversion process is the most conventional method to exploit the shale oil with mid-low maturity. But it is difficult to simulate the key production mechanism of this process, which is always thought to be the key to the reservoir engineering technology of shale oil development. Based on the kinetic reactions of HT pyrolysis of shale oil in Green River formation in USA, the numerical simulation method is established and the formation properties and the well pattern of the pilot test of SHELL is used to model the temperature, permeability, oil saturation, gas saturation, coke and kerogen content, which was used to characterize the key mechanisms of the in-situ upgrading process of shale oil. The technology achieved in this paper provided an important technical guidance for the reservoir engineering design of domestic shale oil development by electrical heating.
