Abstract

The invention discloses an oil layer ignition method and device, a storage medium and a processor. The method comprises the steps that oil layer parameters of a to-be-ignited oil layer are acquired, wherein the oil layer parameters at least comprise the oil saturation of an oil layer, the ignition heat required for stable combustion of the to-be-ignited oil layer, the fuel deposition ratio corresponding to the ignition heat and a first corresponding relation used for representing the oil saturation of the oil layer and the fuel deposition ratio; a second corresponding relation used for representing the fuel deposition ratio and the heating rate of the oil layer is acquired; according to the first corresponding relation and the second corresponding relation, a third corresponding relation used for representing the oil saturation of the oil layer and the heating rate of the oil layer is determined; according to the third corresponding relation, it is determined that the heating rate of the oil layer corresponding to the oil saturation of the oil layer is ignition heating rate. The oil layer ignition method and device, the storage medium and the processor solve the technical problem that the ignition of the oil layer with the low oil saturation does not succeed easily.

Description

technical field [0001] The invention relates to the field of oil recovery in heavy oil oil fields, in particular to an oil layer ignition method, a device, a storage medium and a processor. Background technique [0002] In recent years, the technology of burning oil layer has gradually moved from laboratory research to field test and industrial application. Among them, the vertical well fire flooding technology can be applied to the old heavy oil area that has reached a high degree of recovery in the later stage of steam injection development. [0003] Table 1 shows the economic limit air-oil ratio and the lower limit of the average remaining oil saturation under different oil prices. As shown in Table 1, the economic limit air-oil ratio and the lower limit of the average remaining oil saturation are developed through different well patterns under different oil prices under different oil prices. The demonstration shows that when the oil price changes from US$30 / barrel to US$...
