Abstract
A thermal recovery construction method includes the steps of determining design parameters of a current thermal recovery construction according to geological data and reservoir characteristics of a current oil deposit area to be stimulated; preparing, according to the design parameters, coal water slurry required for the current thermal recovery construction; injecting the coal water slurry into a target reservoir through an injection well with an injection mode of the design parameters, along with combustion adjuvant with an amount selected based on a total injection amount of the coal water slurry; and inducing spontaneous combustion of the coal water slurry by thermal energy generated by a downhole heating device, and performing control and displacement on the reservoir with the thermal energy and gas generated after the combustion.
